If you have finished using Jarfix and want to remove it from your Windows computer, the good news is that uninstalling Jarfix is one of the simplest removal processes you will ever encounter with any Windows program. Unlike most software, Jarfix does not install anything on your computer when you run it. It is a completely portable standalone executable file that does not create any program folders, does not add any entries to your Windows Programs list, and does not leave any leftover files or folders on your system after use.
This guide explains exactly what Jarfix does and does not install on your Windows computer, how to completely remove it, and what happens to your .jar file association after you remove Jarfix from your system.
Does Jarfix Install Anything on Your Computer?
No, Jarfix does not install anything on your Windows computer when you run it. It is a portable standalone executable that performs one specific task when you run it: restoring the correct .jar file association in your Windows Registry. Beyond this Registry change, Jarfix does not create any program files, does not add any folders to your Windows directory, does not add any startup entries, and does not run any background processes on your computer.
Because Jarfix does not install anything, it also does not appear in the Windows Programs and Features list or in the Windows 11 Apps and Features settings. You will not find an uninstaller for Jarfix anywhere on your computer because no uninstaller was ever created for it. The only thing you need to do to completely remove Jarfix from your Windows computer is delete the jarfix.exe file itself.
Note: The only change Jarfix makes to your Windows system is restoring the .jar file association in the Windows Registry. This change is intentional and beneficial as it allows your .jar files to open correctly through Java. Removing jarfix.exe does not undo this Registry change.
How to Uninstall Jarfix from Windows
Uninstalling Jarfix from your Windows computer is as simple as deleting the jarfix.exe file. There is no uninstaller to run, no programs list to navigate through, and no leftover files to clean up. Follow these simple steps to completely remove Jarfix from your Windows computer.
- Find the jarfix.exe file on your Windows computer. It is most commonly saved on your Desktop or in your Downloads folder.
- Right-click on jarfix.exe to open the context menu.
- Select Delete from the context menu to move jarfix.exe to the Windows Recycle Bin.
- Right-click on the Windows Recycle Bin on your Desktop and select Empty Recycle Bin to permanently delete jarfix.exe from your computer.
- Click Yes on the confirmation dialog to permanently delete the file.
Done: Jarfix has been completely removed from your Windows computer. No leftover files, folders, Registry entries beyond the .jar association fix, or background processes remain on your system after deleting jarfix.exe.
What Happens to Your .jar Files After Removing Jarfix
After you delete jarfix.exe from your Windows computer, your .jar file association remains in place exactly as Jarfix set it up. Removing the jarfix.exe file does not undo the .jar association fix that Jarfix applied to your Windows Registry. Your .jar files will continue to open correctly through Java after you remove Jarfix from your computer.
However it is worth keeping in mind that if an archive program like WinRAR or 7-Zip steals your .jar association again in the future, you will need to download Jarfix again from the official developer website and run it again to restore the correct association. This is why many users choose to keep jarfix.exe saved on their Desktop or in a convenient folder even after using it, so they can run it again quickly whenever the problem recurs without needing to download it again.
Pro Tip: Instead of completely removing Jarfix, consider keeping the jarfix.exe file saved in a dedicated tools folder on your computer. It is only 73 KB in size so it takes up virtually no storage space, and having it readily available means you can fix your .jar association again instantly whenever it gets stolen by an archive program in the future.
How to Uninstall Jarfix v3.0 on Windows 10
Uninstalling Jarfix version 3.0.0 on Windows 10 follows the exact same process described above. Simply locate jarfix.exe on your Windows 10 Desktop or Downloads folder, right-click on it, select Delete, and then empty your Windows Recycle Bin to permanently remove it. There is no separate uninstaller for Jarfix v3.0 on Windows 10 and no entries to remove from the Windows 10 Programs and Features list.
If you previously ran Jarfix on your Windows 10 computer and want to confirm there are no leftover files anywhere on your system, use the Windows 10 search feature to search for jarfix across your entire computer. The only result that should appear is the jarfix.exe file itself in whichever folder you saved it to. If you have already deleted jarfix.exe and emptied the Recycle Bin, the search will return no results confirming that Jarfix has been completely removed from your Windows 10 computer.
How to Uninstall Jarfix on Windows 11
Uninstalling Jarfix on Windows 11 is identical to the process on Windows 10. Locate jarfix.exe on your Windows 11 Desktop or Downloads folder, right-click on it, and select Delete to move it to the Recycle Bin. Then right-click the Recycle Bin and select Empty Recycle Bin to permanently remove jarfix.exe from your Windows 11 computer.
On Windows 11 you can also use the Windows 11 Search feature to confirm Jarfix has been completely removed. Press the Windows key, type jarfix in the search box, and if the search returns no results then Jarfix has been completely removed from your Windows 11 computer with no leftover files remaining anywhere on your system.
Does Removing Jarfix Affect Your Java Installation
No, removing Jarfix from your Windows computer has absolutely no effect on your Java installation. Jarfix and Java are two completely separate programs. Jarfix only modifies the Windows Registry entry that connects .jar files with your existing Java installation. Deleting jarfix.exe does not modify, damage, or remove your Java installation in any way.
Similarly, uninstalling or updating your Java Runtime Environment after running Jarfix will not remove or undo the .jar association fix that Jarfix applied. Your .jar files will continue to work correctly through Java after any Java update unless an archive program steals the association in the meantime.
