The Best Tools for Windows included in jv16 PowerTools:

  • Clean and Fix my Computer. Finds and takes care of registry errors, unneeded registry junk, unneeded files, left-over temporary files, unneeded log files and much more. Everything in one go!
  • Fully Uninstall Software and Leftovers. Lists and helps you to remove any software installed to the system, including left-over traces of old software you cannot uninstall by normal means.
  • Control which Programs Start Automatically. See exactly which programs and DLL files start automatically with Windows and disable the ones you don’t really need. Makes it very easy to speed up the startup time of your computer.
  • Speed up Computer’s Startup. Allows you to easily apply tweaks to Windows in order to improve its performance.
  • Immunize My Computer. Easily block access from your computer to known malicious websites in order to improve your safety and privacy. Allows you to block adware and spyware by automatically modifying the Windows hosts file.
  • Decrap my Computer. Allows you to easily mass uninstall software from your computer. This is especially handy for un-bloating new computers by removing the pre-installed software bloat that come with almost every new computer.

Other Awesome System Utilities for Windows included in jv16 PowerTools:

  • Find and replace data inside files
  • Find and replace data from Windows Registry
  • Merge files
  • Split files
  • Remove files on reboot
  • Wipe file
  • and many others

Changes in jv16 PowerTools Beta:


  • Major improvements to the responsiveness and overall smoothness of the UI.
  • Major user interface improvements in both how the overall user interface looks like, but especially how easy it is to use.
  • Major reduction to the average time it takes to run the Initial Setup.
  • Entirely rewritten hard drive information area in the Dashboard now shows more detailed data.
  • Highly improved Settings window user interface.
  • Reduced the CPU usage of the Widget.
  • The legend popup panel will now automatically close in Widget after it has been visible for a few seconds.
  • It’s now possible to change the order of the dashboard content. And there is more freedom to choose what is displayed there.
  • The result list columns are now sized based on their content. And, if you don’t like this, you can also choose them to be equally sized. This option was added to Settings.


  • In some rare cases, running the System Cleaner can remove a non working AutoDesk licensing service module. This happens because the module is not working correctly. However, if it is removed, AutoDesk software will stop working and need to be reinstalled. While this is technically not a bug in jv16 PowerTools – it removes a non working service module from the system as designed – the issue is now fixed by ignoring such AutoDesk related services.
  • Running the System Cleaner with the “Do not list temporary files which could be dangerous to delete” safety setting disabled (it is enabled by default), can damage Windows 10 Start Menu’s pinned tiles feature (which is also not enabled by default).
  • System Cleaner can get stuck to the final “Please wait” phase. This bug is relating to many factors and does not happen often, but the more results are found, the more likely this was to happen.
  • In rare cases, the “The scan took x seconds and found a total of z registry errrors” etc text in the System Cleaner results screen can contain wrong numbers. This could happen if the ignore list feature is used, and some found items were ignored but they were still counted as found errors – which is technically correct, but would be confusing for the user.
  • Running the System Cleaner can get stuck to five or more minutes in some systems. This bug is relating to incorrect (read: slow) processing of certain type of data, only found on some systems. It should now be fixed, and the System Cleaner is also now faster overall.
  • After returning to the Dashboard, there can be a delay of few seconds during which time the UI is not responding.
  • The Dashboard and the Widget could sometimes show an incorrect icon for a running app. This was purely a cosmetic issue, but it’s now fixed nevertheless.
  • Scrolling the Dashboard area up and down can cause the running apps list to flicker. This is also entirely a cosmetic issue.
  • Dashboard and Widget app listing could show apps with “< 1%” and “0%” CPU usage which is both superfluous and potentially confusing.
  • If you hide hard drives from the Dashboard view, it is required to restart the app to be able to see the hard drives again.
  • Dashboard or the default view of tools can display a horizontal scroll bar, which is not visually very pleasing to see if not absolutely needed.
  • Task Closer’s software column contains empty items, which is not visually pleasing. All cases of no software name are now filled with ‘(n/a)’ text instead.
  • If you click the button to start a tool while it is already scanning, this will abort the scan which makes no sense. For example, if you click System Cleaner button from the menu, while System Cleaner is already scanning.
  • The Dashboard and the Widget app can fail to display an icon of a running app, and instead an empty space is displayed.
  • The result list search feature could become visible before the results, making the user interface to look confusing.
  • Running the Finder after Duplicate Finder can cause the Finder results list to incorrectly include the Duplicate ID column. This is simply a left-over from running the Duplicate Finder and entirely a cosmetic issue.
  • It’s possible that more than one instance of the app can be started at the same time, and if that happens, the app may simply close without an error message.
  • The program could show an error message about Access Violation when closed.

Changes in jv16 PowerTools

Feature Improvements:

  • Scanning and cleaning speed of System Cleaner is now a lot faster.
  • The program is now compatible with the upcoming Windows 11.
  • Improved the Software Uninstaller’s ability to find and delete left-over data.
  • The setup executable now also has the executable file information fields set, such as file comments.
  • Reduced the size of log files created during System Cleaner usage.
  • Added “Check For Updates” also to the Tools menu of the main window. Previously, it was only under the Help menu.
  • Comes with updated Dutch, Polish, Russian and Swedish translations.

Bug Fixes

  • Performing a full system cleanup with the System Cleaner can take a very long time, with the progress indicator seemingly stuck at 90% or at 99% in some systems.
  • System Cleaner does not always find all the possible temporary files for removal.
  • If you do a full system cleaning with System Cleaner, and then run the scan again, it can still show more items to clean. This can repeat for many times, if not forever.
  • System Cleaner can fail to detect some broken shortcuts.
  • Some parts of the Settings window UI are not rendered correctly in all screen resolutions and application window sizes making some texts of check boxes invisible.
  • The Check For Updates screen can display a blank screen on some systems.
  • If you abort a system cleaning session, the checkbox about restarting computer remains visible on screen for a few seconds while the progress screen should only contain information that the operation was aborted. This is a cosmetic issue, but fixed now nevertheless.
  • In some systems, starting the app or running the Initial Setup could cause Windows to display error message saying “This operation has been cancelled due to restrictions in effect on this computer”.
  • When a message box is shown, it will by default display the blinking text caret (cursor). It can look a bit confusing as to why there is one. It’s now fixed. You can still place the caret there by clicking the message box text with your mouse cursor and select text for Ctrl + C.
  • Running jv16 PowerTools on a screen with a very small resolution (e.g. 800×600 px), the navigation panel can be drawn without any content (no icons) and no texts.

    Been using it for a while. Tried the “disk cleaner” and “compress registry” doesnt seem to work on my windows 7 64bit. Although i must admit, i love this program, really nice and feels safe

    This app is not so friendly to Windows 7, IMO.
    The body is getting bloated and the text is
    getting smaller which unable to be enlarged.
