New Update Uninstalr 3.0 released - and compared against the most popular uninstallers (Revo Uninstaller/Geek Uninstaller/BCUninstaller etc)

[jv16]

After about one year in development, Uninstalr 3.0 is finally ready. It’s a freeware, lightweight software uninstaller for Windows that supports unattended, batch uninstallation of many apps at the same time, as well as removing those tricky apps whose own uninstaller doesn’t work for some reason.

It comes as a single executable file portable version or as a normal setup version. You can download them from Uninstalr

The key improvements compared to version 2.8 are:

• The installed apps list now shows the country of origin for all known installed apps.
• The main user interface and the before uninstallation paths view both now display checkboxes, allowing easier selection of data to be removed.
• The main window bar now includes Settings and About buttons.

The full changelog is available at: Uninstalr Features

This is how it looks like in dark mode:

Notice how the version 3.0 can now show the Country of Origin data of your installed apps. This is one of the many unique features that Uninstalr offers that other uninstallers don’t.

And speaking of the other uninstallers, since the number one question that I always get about the software is “how does it compare against Revo/BCU/Geek/etc”, I wanted to properly answer that with a new comparison.

The comparison is available here: Windows Uninstaller Performance Comparison 2026 - Uninstalr Blog

In it, I perform these three tests: 1) How well different uninstallers can detect portable apps and leftovers from already uninstalled apps, 2) How many leftovers remain after uninstalling some popular apps with each of these uninstallers, and 3) How well can these uninstallers remove an app whose builtin uninstaller fails to work.

The results are, well, not great to say the least.

I’m the developer of this app, so feel free to let me know if you have any questions or feedback. If you find any bugs, please let me know and I will do my best to fix them. Thanks!

Thanks for the update.

Uninstalr 3.0 looks like a meaningful release, especially the improvements around batch removal, unattended uninstall support, and handling broken uninstallers.

A few points that stand out from a Windows maintenance and cleanup perspective:

• A portable single-file option is useful for troubleshooting systems without committing to a full install.
• Batch uninstallation can save a lot of time, but it also increases the risk of removing shared components or user data if selections are made too aggressively.
• The added checkboxes for paths and removable data should make the workflow clearer than older “scan and confirm” approaches.
• Showing country-of-origin information is unusual among uninstallers. It may be useful for inventory and transparency, although it should not be treated by itself as a security or trust indicator.

On comparisons with Revo, BCU, Geek, and similar tools

It is good that you published a methodology page, but in general, vendor-run comparisons should be read with some caution because test design can strongly affect the outcome.

The most useful points for members will probably be:

• Whether leftovers were measured consistently across all products
• Whether default settings or maximum-aggressiveness settings were used
• How registry leftovers were weighted versus actual disk/file leftovers
• Whether failed uninstall scenarios were reproducible on a clean test system

For most users, the practical difference between uninstallers is usually not just “who removes the most,” but also:

• How reliably they avoid false detections
• How clearly they show what will be removed
• How easy it is to restore from mistakes
• How well they behave on modern Windows 10/11 systems

A general caution for users

Advanced uninstallers can be helpful, but they are not risk-free. Any tool that removes leftovers beyond the vendor’s own uninstaller can potentially remove something the user later wanted to keep, especially logs, settings, caches, shared folders, or registry entries.

A sensible approach is:

• Create a restore point or system image before major cleanup
• Review all detected leftovers before confirming deletion
• Be extra careful with batch removals
• Avoid treating “more aggressive” as automatically “better”

Overall, this looks like a substantial update, and the UI changes sound practical rather than cosmetic. The most important thing for users will be consistent real-world reliability and conservative cleanup choices when needed.

Thank you for redoing this test yet again. I'd be delighted to perform another round of testing with all the uninstallers, just as soon as I'm back to Windows, which should be sometime around 2032 or whenever Microsoft decides to grace us with Windows 12.

Until then, I'm happily surviving on Linux, where these issues are rare enough to feel like urban legends.

I just watched the comparison video and noticed that you interrupt the uninstallation process for almost every uninstaller program, then count the remaining files. Is this a speed test or what? From my point of view, it is not a fair test.

Been using, and no complaints, I have Jv16 power tools subscription, but believe this is freeware, worth a try, shows a lot more stuff

I didn’t watch the full video, but at 18:57 you can clearly see the dev hit “skip” in HiBit while uninstalling Discord just to rush the process. That alone adds bias and hurts the test’s credibility

I would love to see an independent test of uninstaller software. It could uninstall programs like Microsoft Office, Adobe products, and even security software. I’d be especially interested in seeing how each uninstaller handles security software, since improper removal could pose risks to system stability.
