What's new in this version:

jv16 PowerTools 5.0.0.939
Improvements:
- Major accuracy improvements to the Initial Setup, System Cleaner, Software Uninstaller and Software Updater scans
- The Use Custom Main Menu option will now be disabled by default on systems with multiple monitors. This feature doesn't work properly on systems with multiple monitors, this is a quick workaround until we have a proper fix
- The program will now detect if major changes have been made to the system since the Initial Setup was originally run and it will be run again to ensure the most accurate analysis of the system
- Pressing Ctrl + A while a tool's result filter is active now selects the filter text, instead of selecting all of the result list items
- The Languages menu and the Tools menu are now hidden from the main menu while the tool is scanning. Previously, one could change the language of the program during scanning, which made the scanning stop as the program needs to restart for the language change


jv16 PowerTools 5.0.0.845
Fixed:
- Running the System Cleaner can damage Mozilla Firefox or Mozilla Thunderbird products. This only occurs in some systems, but we wanted to release a fix for the issue as fast as possible nevertheless. A simple reinstall of the mentioned products solves the problem, or restoring the System Restore Point jv16 PowerTools automatically created before the cleaning.
- The Initial Setup can fail with an error message of Access Violation. This is a very rare bug, but now also fixed

Improvements:
- Speed improvements to the Initial Setup, Software Uninstaller and Software Updater scans


jv16 PowerTools 5.0.0.832
Fixes:
- Maximizing or unmaximizing the main window by double clicking the top window bar does not work properly
- If you maximize the main window, then minimize it, clicking the jv16 PowerTools in Windows task bar does not restore its window and the program can remain invisible
- The Please restart jv16 PowerTools message box can be shown with the wrong message box icon
- Software Uninstaller and Software Updater can show wrong version number for some software, for example Speccy
- Uninstalling many software at the same time can cause the progress screen to display incorrect paths. For example, if you are uninstalling Winzip and Winrar, during the uninstallation of Winrar, the progress screen could say it is processing C:Program FilesWinzip. This is a purely cosmetic problem relating to the user interface. No incorrect data is removed, or data of other software
- Uninstalling certain software can cause the system to reboot incorrectly. This is caused by Software Uninstaller not detecting a certain type of reboot now or later selector in the app's uninstaller
- The scan progress screen of Find All and Finder tool can display incorrectly large number of results found. This is purely a cosmetic issue, the user interface simply counted the data wrong and that is why the number of items found shown on screen does not always match the final number of found items

Improvements:
- Major speed improvements to Software Uninstaller and Software Updater scans
- Minor improvements to the accuracy of Software Uninstaller
- Minor performance improvements to Find All and the Finder tool


jv16 PowerTools 5.0.0.798
New features:
Finder:
- This tool allows you to search for files and registry data with more advanced set of features compared to the Find All feature. Find All is your quick way to find what you want. The Finder is for you when you want to be more detailed what to find and from where.

Duplicate Finder:
- This tool allows you to find duplicate files. The duplicate detection can work either by file content, listing you files which have 100% bit-by-bit identical content, or by filename allowing you to list files with identical names. Or, both: duplicate files with identical content and name. This feature is designed for finding duplicates from your file collections, such as collections of documents, pictures or movies.


jv16 PowerTools 5.0.0.786
Fixed:
- Aborting a scan and then starting it again does not always work, instead, starting the scan again will only show the aborting scan screen again
- The program can display an error message about floating point divizion by zero in some rare cases
- The Internet Optimizer can fail to run without showing any error message, it would simply return to the home screen
- Find All's Ignore List is not always properly initialized. For example, jv16 PowerTools's own debug folder should by default be ignored, but this does not always happen
- Scan progress screen's font sizes can change during a scan without any good reason
- The program can fail to detect all the installed browsers from the system, which leads them not being listed in jv16 PowerTools Settings window
- Sometimes clicking the top bar of the main program window is incorrectly interpreted as a double click, causing the window to get maximized
- Internet Optimizer can get stuck when applying the new Internet settings
- The Registry Backups Disabled popup can be shown annoyingly immediately after the Initial Setup has completed and the main window shown. Now, there is a small delay before it can be shown
- Initial Setup can fail and show an error message in some systems
- Software Uninstaller can fail to uninstall software with an error message "Error No uninstallation data found. Nothing to do.
- Running System Cleaner can leave orphaned threads running in the background. While they don't normally cause any problems, they can make the program seem slow and use more RAM than expected
- The tools can get stuck to the Adding Data To Screen phase, especially if the tool was ran after using System Cleaner. This was a rare bug, only occurring in some systems, and only sometimes
- After you first start the program, the tool tips on the main program window are correct. However, after you start the program again, the tool tip texts are cropped, with only the first sentence visible
- System Cleaner does not always detect all of the broken shortcuts from Windows Desktop or Start Menu. This is a false negative type of bug, meaning not all broken shortcuts were detected
- Sometimes the tool icons on the main screen can have jagged edges
- In some systems, maximizing the main program window can make it cover the Windows task bar
- Buttons may be drawn using a slightly incorrect color. This cosmetic issue can happen, for example, if you click the Close button of a tool, and then re-open it and repeat this a few times

Improved:
- New tool: Task Closer. This tool allows you to maximize the performance of your computer and your mental focus by closing background processes and notification windows during gaming or working
- New tool: Software Updater. This tool allows you to see which of your installed programs and games are outdated and allows you to start the download of the latest versions with one click
- New tool: Command Prompt mode allows you to execute simple commands by typing them to the main screen. This feature is especially handy for people who have used to using computers more using the keyboard and not mouse
- Greatly improved the error resistance of the Internet Optimizer. Before, the entire process could fail if few DNS server benchmark tests failed, for example due to some limitations to the internet connection. Now, it will simply automatically try tests again and proceed even if minor failures occur
- Improved the error message for local DNS server settings
- Improved Software Uninstaller's ability to detect the version information of software
- Greatly improved Software Uninstaller's ability to detect the installation date of software
- Greatly improved System Cleaner's ability to detect leftovers from software which have been uninstalled after jv16 PowerTools has been installed
- The program will now start with less flickering of the main window user interface
- Find All's default ignore list now also includes the system temporary data directories
- Improved the scaling for 4K displays. The program still doesn't look perfect at 4K resolution, but it's now a lot better. We will improve the 4K support with the next versions
- The superfluous Close button bar at the bottom of certain tools, such as the Support page, will now be hidden if the window size is too small to accommodate it. This will free more space to the actual content on screen
- User can now choose which tools are available in the home screen, and whether the System Cleaner should have a larger icon
- The License Agreement has been updated to include detailed information what kind of data jv16 PowerTools sends to us. In short, it sends statistical information to help with our quality control and product development. The only personal information is sent if you use the My Account tool to activate your copy of the program, this will naturally send the name and email address you input to the tool
- The program will automatically prune old debug logs from its debug folder
- Internet Optimizer now uses less than 40% of the resources it used before
- Massive speed improvements to the Initial Setup. In some systems, Initial Setup is now up to 400% faster. The speed improvement is based on improved analysis of very specific type of data. If your system doesn't happen to have this data, the speed improvement might be very minor for you
- The font of the tool name is now better adjusted based on screen size, causing less window real estate to be used for the tool name text and freeing up more space for the actual tool user interface
- Improved the detection of windows to close in Task Closer
- Greatly improved the program's ability to detect installed software before Software Uninstaller has been run. This improves the accuracy of the System Cleaner and the list of available software in Game Booster
- Added a one time confirmation to Task Closer
- The default listing of Software Updater only consists of the software that should be updated
- Software Updater now considers version such as 1.53.0.1088 and 1.53.1087 to be equal, even though they technically are not, but certain software publishers use these interchangeably and that caused some incorrect update analysis results in Software Updater before
- Optimized the program's memory usage, and this version will again use less RAM than before
- Improved the usability of the program using only a keyboard - now pressing Ctrl + Enter will press the default button of the currently open tool
- Improved support for systems with multiple monitors
- Resizing the main program window now works faster and smoother


jv16 PowerTools 5.0.0.730
Fixed:
- Bug fix: If certain files are deleted in jv16 PowerTools installation folder, the program can enter a state where it runs the Initial Setup every time the program is started
- Bug fix: The program shipped without the list of available DNS servers used by the Internet Optimizer, causing the Internet Optimizer to not being able to run
- Bug fix: Software Uninstaller can incorrectly add a trailing slash to filenames, for example path c:windowsnotepad.exe can become c:windowsnotepad.exe. While this is mostly a cosmetic issue, it can also affect the uninstallation software as if the program attempts to uninstall software and delete such path, it may fail because of the incorrectly placed trailing slash character
- Bug fix: Using Find All with a search term that produces zero results causes the small under window progress bar remain visible in the main window after the search has ended
- Bug fix: Find All's vertical position on the home screen can change for no reason
- Bug fix: Opening the Settings can take a very long time in some systems
- Fixed many cases of bad English from the program's user interface. Mostly grammar mistakes

Improvements:
- Major speed improvements in the entire program. In our testing systems, the Initial Setup is now on average 18% faster, System Cleaner 20% faster and Software Uninstaller up to 50% faster
- Major improvements to Software Uninstaller's ability to find left-over traces of software
- Major improvements to the System Cleaner. In our testing systems, it now finds on average 20% more errors
- Software Uninstaller can now better detect the installation date of software
- Improved the way the Find All will catch keystrokes even if its not in focus when user starts to type in the home screen


jv16 PowerTools 5.0.0.697
Fixes:
- Bug fix: Uninstalling software can cause the Windows user interface (explorer.exe) to be terminated. This is by design. However, after the uninstallation, it should be restarted again. Bug mainly affects Windows 8
- Bug fix: If you use the Results Search feature within Find All, the blue category bars with the number of found items are not updated to reflect what is currently on screen. Instead, the number of items in each category remains the same as if no Results Search is not used at all. This only affects the number of results reported, the actual searching of results is working correctly
- Bug fix: You cannot use Ctrl + A to select all the text in the Software Uninstaller > Uninstall Software screen
- Bug fix: In some systems, the automatic detection of Whitelisted Domains to be listed in Settings > System Cleaner does not work, and no domains are listed
- Bug fix: Software Uninstaller can incorrectly list some software twice, with and without a version number in the program's name
- Bug fix: Find All's group captions are not correctly capitalized. For example, file paths can be incorrectly starting with a non capital drive letter
- Bug fix: The default sort of Software Uninstaller is incorrect
- Bug fix: System Cleaner can incorrectly say some Windows application shortcuts, such as the Snipping Tool, are broken and not working, even if they are working. This bug is rare, we were not able to even reproduce it but nevertheless, it is now fixed
- Bug fix: Restoring a backup with the Backup tool can cause Windows RegEdit.exe error message to show up
- Bug fix: The bottom status bar texts in the main window are not always correctly positioned (not centered)
- Bug fix: Some parts of the user interface cannot be translated because the texts are missing from the translation file (English.lng
- Bug fix: Applying filters in System Cleaner, Software Uninstaller or Find All result screens does not hide the filter panel while the screen updates
- Bug fix: System Cleaner's progress screen can display a number of errors founds to be larger than actually listed in the result screen. This is a cosmetic bug, caused by the scan progress screen counting all found items, and the final result listing containing only items without any duplicate data and without results matching the user defined ignore lists
- Bug fix: Find All's result list processing will become very slow with a lot of data (10000+ rows) and the counts, such as the number of items on screen, can be inaccurate
- Bug fix: If you use the Settings window to hide Find All from the home screen, and then re-enable it again, the Find All box is incorrectly positioned in the home screen
- Bug fix: Uninstalling software with the Software Uninstaller can get stuck to long periods of time (30 minutes+) when uninstalling certain software. This only happens in some cases, and with some software
- Bug fix: System Cleaner's result screen always contains a long English text, even if you are using the program in another language
- Bug fix: The scan progress screen can display a cosmetic mistake by showing hkey_local_machinesomekey - (full key). The trailing character is incorrect here
- Bug fix: Even if you list the installation directory of software in the Settings > Ignore List, under some rare cases, the Software Uninstaller can still list the software. This does not occur if you also list the software's name in the Ignore List

Improvements:
- The program now starts a lot faster. On average, the previous build took 11 seconds to fully start, this version takes on average only 4 seconds
- Greatly improved the speed of uninstalling software with the Software Uninstaller
- Greatly improved the performance of Results Search and the result list filtering features when dealing with lists with a lot of data
- Improved the accuracy of the Software Uninstaller. It again finds more data to remove when you use it to uninstall software
- Improved Software Uninstaller's ability to delete locked and otherwise write protected data
- Improved the progress reporting of uninstalling software
- Improved System Cleaner's ability to find more leftovers from old software
- Improved System Cleaner's detection of which registry data is relating to which installed software or left-over software. This will make the analysis of the results list a lot easier when you can see what is relating to which software
- Improved the speed of System Cleaner scan
- It's not meaningful to display the number of issues found during the System Cleaner scan because the number is not final before the final post processing phase, which takes two seconds just before the scan completes. The previous versions showed the number of possibly found issues, but this is not accurate and could lead to confusion with users. Therefore, this is no longer shown
- Improved the user interface after you click the Uninstall button in the Software Uninstaller. Before, you saw a progress animation. Now you see an actual progress bar
- Starting to type in the home screen now automatically moves to focus to Find All, allowing you to start a Find All search without first having to click its search box to become active
- Ctrl + A in the home screen will now select everything in the Find All's search box
- The main program window now starts with less visual flickering and elements moving around immediately after the window becomes visible
- The program will now display a message on its main window if a new version is available for download. Before, user would have to use the Help > Check For Updates to see this information
- Improved the accuracy of the progress reporting, especially when cleaning the system with System Cleaner and uninstalling software with Software Uninstaller
- The installation file of the program is now better in detecting and closing any instance of jv16 PowerTools, to ensure a smoother update process


jv16 PowerTools 5.0.0.675
We originally released build 668 yesterday. It had passed all our quality control tests and all seemed good. However, there were three annoying bugs:
- Many parts of the user interface show in English, even if user is using a translation. This happens only on certain tools or pages inside the program, such as in My Account
- Using the new Results Search features in System Cleaner can cause it to go into an eternal loop where the screen blinks or flickers with text "adding data to screen"
- Using the System Cleaner's Right Click Menu option to ignore result rows can cause the program to show an error message about Access Violation and close
- This build fixes these unfortunate bugs that were in the build 668. I would like to apologize for this problem - we spent hours upon hours in testing, yet we failed to notice these bugs. It's embarrassing and I apologize

- Bug fix: System Cleaner, Software Uninstaller and the Find All results can forget the set column widths and always start with the first column resized very small
- Bug fix: Saving a results list from File > Save List as produces a file without any file extension if you only write a filename without file extension
- Bug fix: Uninstalling certain software, such as CDBurnerXP, can cause the Software Uninstaller to get stuck and never complete. This only occurs with some systems, and with some software being uninstalled
- Bug fix: Pressing Ctrl + A to select all the items of System Cleaner, Software Uninstaller or Find All results may trigger the result list filter update to run again. This is a cosmetic issue but nevertheless, annoying and now fixed

Improvements:
- New Feature: Software Uninstaller now shows the size of each installed software, their installation date and as an unique feature, the impact each installed software has on your system's performance

-The previous version fixed the problem about Firefox bookmarks being modified or removed during System Cleaner. The original bug was rare, only occurring in some systems. The last version fixed it for many users but not perfectly. This build now fixes it for good
-The program may fail to start on some systems. If this happens, you will only see the initial splash screen and nothing else ever shows up
-The Initial Setup can take a very long time to run on some systems
-Tools menu > Maintenance > Flush Cache does not trigger the Initial Setup to run again, even if it says it would
-If you don’t have a browser installed, for example Firefox, the System Cleaner will still search for its cookies and history data. This makes the scan a few seconds slower than what it should be
-System Cleaner can incorrectly say no items found even if some were found
-On small screens the splash screen’s bottom texts can overlap the version number text
-System Cleaner can ask for permission to close web browsers even if you have selected not to run any browser related cleaning modules
-System Cleaner can search for temporary files even if the temporary file scan module has been disabled from Settings
-The Ignore List may not work in cases of you want to ignore certain types of registry data, and the System Cleaner will therefore continue to list this data
-Starting the System Cleaner can show confirmation text in English, even if you are using the program in another language
-The program can display Stringlist Out Of Bounds error when starting. This is a very rare issue, happening only in some systems
-Ignoring software with the Software Uninstaller via the Right Click menu does not remove it from the list, it is only not shown the next time even though System Cleaner removes the item from list immediately after item is ignored
-Internet Optimizer can get stuck in the Starting … screen

Feature Improvements:
- Improved the detection and the listing of browser cache data
- System Cleaner’s information message boxes are now shown only if System Cleaner is open and active
- Made the user interface for the System Cleaner settings clearer
- Installing a new version of PowerTools over the old one causes in some cases of important (but not critical) cache files never to be created, as the Initial Setup has already ran when the old version was installed. Now, the program will detect if such cache files are missing and perform an Initial Setup again if needed
- Increased the waiting thresholds of information messages in the application to avoid too many tips or other non essential message boxes to be displayed in too rapid progression
- All the three main tool text captions are now visible. Before, only the default tool or the currently selected tool caption text was visible, which some users found difficult to use
- The program will now attempt to detect a running setup of jv16 PowerTools and automatically close itself. This way you are not prompted with an error message of a file in use if you try to update while the program is still running
- My Account’s Apply button is now only visible if needed
- Aborting a scan can cause the user interface to get not responsive. Therefore, the Aborting scans feature is currently not available until we improve and fix it


jv16 PowerTools 5.0.0.513
Bug Fixes:
- Choosing to clean the cookie or history data of only some browsers in the Settings window can cause the System Cleaner not to clean any browser cookie or history data
- The “Congratulations! No errors or unneeded data found from your computer” message may get stuck in a loop and displayed over and over again after the System Cleaner
- The top one pixel of the message box window’s buttons many not be visible if the system is using higher than 100% font size setting in Windows
- Fixed a misspelled word “erros” from the English user interface (should be “errors”)
- The check for multiple program instances is not always working, allowing user to run multiple instances of the program at the same time
- Internet Optimizer can edit the DNS settings set by installed VPN or internet security software suite. This has now been addressed by detecting these settings and informing user that the Internet Optimizer cannot be run in this case
- Running the Software Uninstaller can display an error message relating to converting date. This is a very rare issue, happening in under one system in one hundred
- The scan progress screen can display lines starting with an empty space character. This is a cosmetic issue but fixed now nevertheless
- The program can display gray color panels behind texts if user is using Windows with the classic theme or high contrast theme enabled
- Uninstallation of software with the Software Uninstaller can display the warning message of uninstalled software being similar to another software multiple times
- The System Cleaner can list firewall policy registry entries which are recreated by Windows
- Adding a drive letter to the Ignore List will not prevent software from that hard drive being listed in the Software Uninstaller
- Closing the program too soon after running the Initial Setup can cause the Initial Setup to be run again on the next time the program is started
- System Cleaner’s check boxes are incorrectly aligned if user’s system is using large fonts in Windows settings
- The program can fail to detect installed browsers in some systems and this causes the browser cleaning options of these browsers not to be visible in the Settings > System Cleaner and also not run during System Cleaner
- Some texts from the user interface cannot be translated, i.e. they do not exist in the English.txt file
- The color of the background panels in System Cleaner’s report screen can be incorrect
- The program does not correctly Windows language if it was changed by the user. For example, if you installed English Windows but then downloaded a Windows language pack to change its language to Polish, jv16 PowerTools will not automatically detect and load the Polish translation.
- The program does not close itself if it is still running when user starts the uninstallation of jv16 PowerTools
- Clicking to Abort a scan may cause it to get stuck to a screen with text “Starting …”
- Cleaning browser history data could cause browser bookmarks also be removed or altered in some rare cases

Feature Improvements:
- System Cleaner now lists all the browser history and cookie data per domain, allowing you to choose what data to exactly clear
- The trial reminder or license information text at the bottom right corner of the main window is no longer clickable during the scan progress screen to avoid accidental clicks
- Improved the smoothness of scrolling the System Cleaner and Software Uninstaller result lists
- Improved the scan progress screen’s user interface smoothness. It should now show and update with far less element sizes being changed for no reason
- The Settings window’s Domain Whitelist and Global Ignore List features now automatically remove unneeded rows of data. For example, if you would enter “jv16 PowerTools” and “jv16” to the Global Ignore List, the row “jv16 PowerTools” would be automatically removed as it is already included in the row “jv16”
- Some users have been confused by the Invalid Metadata errors found by the System Cleaner, thinking that such error means that the file mentioned would be deleted by the System Cleaner. This is not the case. For example, if the System Cleaner reports that Explorer.exe has invalid metadata, it does not mean the file would be deleted. Instead, the System Cleaner would only fix its invalid metadata from the file system record
- Improved VPN and firewall and internet security software detection
- Internet Optimizer now refuses to start if the system is using local network based DNS to prevent any compatibility issues, for example with locally run network solution, VPNs, internet security software or locally run servers
- If you enter full URLs to the Domain Whitelist in the Settings window, the program will now know how to process them and only add the domain names
- Added an option to delete unused translations and clear jv16 PowerTools cache files (Tools > Maintenance menu)
- Added an information text to My Account’s user interface to inform the user that an internet connection is required. This is not shown if a connection has already been detected
- Attempting to activate a license in My Account without newsletter subscription setting will now automatically scroll the setting into view
- System Cleaner will now show more information messages relating to the found items. These were designed to address some of the common misconceptions of the results
