Uninstalr is an easy to use and very accurate software uninstaller for Windows. It can uninstall multiple apps at the same time and I think it’s very good at it, too.


Key Features

Uninstalr is freeware, lightweight and easy to use. There are no bells and whistles and no nonsense. Most importantly, Uninstalr allows you to decide how you want to do things. If you don’t want to batch uninstall anything, you can choose to do the uninstallations one by one. If you don’t want a deep level analysis, you can disable that. Uninstalr puts you back in charge of your computer.

Comes with these translations builtin: Chinese Simplified, Chinese Traditional, Czech, Danish, Dutch, English, Filipino, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese, Romanian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian and Vietnamese. There’s no Russian translation, because glory to Ukraine.

 

Screenshots

The main screen shows all the installed software in your system, as well as how much space they occupy.

Uninstalr creates this list by analyzing the entire computer, not merely reading the same list Windows Installed Apps uses.

Before the uninstallation, you will see every single file, folder, registry key and registry entry the specific app has created to your system.

All this data is automatically detected by Uninstalr, and removed if you choose to proceed with the uninstallation.


Uninstalr uses a custom uninstallation engine, that is how it is able to also detect leftovers of previously uninstalled apps.

For example, in this screenshot, leftovers from an old installation of Winzip are detected.

If you want, you can also use Uninstalr to monitor when you install any new app, and it will detect its data while you install it.


Uninstalr’s custom engine analyzes which files and folders were created by the installed apps.

This is how it can also use this data to fix the Windows Installed Apps listing where the space occupied by software information is often incorrect.

For example, in this system Adobe Acrobat is reporting that it is using 666 MB of space, but it is actually using 2 GB of space.

You can make Uninstalr to look and feel the way you want to.

Also notice how it comes with translations builtin. You can change the language of the program’s UI by simply choosing the translation from the list.

And all this is free and under 6 MB!

 

Feature Comparison

I said that I think Uninstalr is the best uninstaller for Windows. So, how does it actually compare against other Windows uninstallers, you might be wondering right now.

Well, aren’t you lucky since I compiled you this handy feature comparison table so you can see for yourself:

Feature Uninstalr Ashampoo UnInstaller FREE Bulk Crap Uninstaller Geek Uninstaller HiBit Uninstaller IObit Uninstaller Free Revo Uninstaller Pro Total Uninstall Uninstall Tool WinToys Windows Installed Apps

* = Geek Uninstaller and Uninstall Tool say they support batch uninstallation, but this feature is disabled from the free trial version.
** = Total Uninstall and Uninstall Tool have a portable version, but the portable version package is available for download only after purchasing a license.

It must be noted that IObit Uninstaller wants to install something called iTop VPN Free and iTop Screen recorder as pre-checked bundled software and it also suggests installing iTopEasy Desktop as an optional bundled software. It is deeply ironic that a software uninstaller wants to install more nonsense to your computer and I cannot express how much I didn’t need these to be installed.


Uninstall Performance Benchmark

I could be talking about features all day long. But at the end of the day, only one thing should define what is the best uninstaller for Windows: How well it can actually uninstall apps.

To test how well these uninstallers really perform, I conducted a simple test to measure just that.

I got myself a VirtualBox virtual machine, I installed a fresh Windows 10, then I installed all the available updates and activated it. Then I installed 28 popular Windows apps. Namely, these: 7-Zip, AIMP, AllDup, Audacity, Blender, Core Temp, Evernote, FastStone Image Viewer, FileZilla, Foxit PDF Reader, Internet Download Manager, IrfanView, iTunes, KMPlayer, KeePass 2, Mailbird, Mozilla Firefox, Mozilla Maintenance Service, Netflix, Paint.net, Spotify, TikTok, Winamp, Winrar and Winzip. Also, when installing iTunes, also Apple Mobile Device Support, Apple Software Updates and Bonjour were automatically installed.

After these software were installed, a snapshot was created of the virtual machine, so the exact same system could be used with each of the uninstallers. Then, one by one and restoring the virtual machine state from the snapshot before each test, I installed and ran each of the uninstallers and used WinFindr to search how many files, folders, registry keys and registry entries remained in the system matching the names of the uninstalled apps. These were counted as leftovers.

Here are the results of this benchmark: How many leftovers of uninstalled apps remain after uninstalling them with the specific uninstaller.

Uninstall method Version Leftovers remaining
Uninstalr 2.0 26
Ashampoo UnInstaller FREE 9.00.00 627
Bulk Crap Uninstaller 5.7.0.0 411
Geek Uninstaller 1.5.2.165 393
HiBit Uninstaller 3.1.81 241
IObit Uninstaller Free 13.3.0.2 553
Revo Uninstaller Pro 5.1.7 440
Total Uninstall 7.6.0 142
Uninstall Tool 3.7.3.5720 448
WinToys 1.2.35.0 445
Windows Installed Apps Windows 10 Pro 22H2 458

Bulk Crap Uninstaller claims to be able to batch uninstall software, but in this test it failed to automate the uninstallation of AIMP, Firefox, KMPlayer, Internet Download Manager, IrfanView, Mailbird, Bonjour and Winrar and it required user’s help in uninstalling these apps.

HiBit Uninstaller claims to be able to batch uninstall software, but in this test it failed to automate the uninstallation of Core Temp, Internet Download Manager, KMPlayer, Mailbird and it required user’s help in uninstalling these apps.

IObit Uninstaller claims to be able to batch uninstall software, but in this test it failed to automate the uninstallation of AIMP, Core Temp, FileZilla, Internet Download Manager, iTunes, KMPlayer, Mailbird, Firefox and it required user’s help in uninstalling these apps.

Revo Uninstaller Pro claims to be able to batch uninstall software, but in this test it failed to automate the uninstallation of Blender, iTunes, Mailbird, KMPlayer, Apple Mobile Device Support, AIMP, Internet Download Manager and Apple Software Update and it required user’s help in uninstalling these apps.

Total Uninstall claims to be able to batch uninstall software, but in this test it failed to automate the uninstallation of Mailbird, Winrar, KMPlayer, Internet Download Manager, IrfanView, Core Temp, AIMP and Firefox and it required user’s help in uninstalling these apps.


You shouldn’t believe everything you see online - even if they use cool charts like the one above. If you want to verify that the above benchmark results are correct, and that the benchmark was performed as described, you can do that with the following video. The video is uncut, unedited entire testing session. Here it is: https://youtu.be/eXg4mcoEJf0


Even with the video showing the benchmark results are real, I suggest everyone do their own research. And by this, I don’t mean to enter the weird side of the Internet, but to repeat the above type of testing yourself. Install some app to a system, uninstall it with different uninstallers and use WinFindr to see how many leftovers remain.

 

Download

The latest version of Uninstalr is version 2.1, released 22nd of February, 2024.

Uninstalr comes in two tasty flavors: Portable and Setup.


The portable version means that you have one Windows executable file that you can simply copy to any system you want and run it there. When you are done, you can just delete the executable file and there is no other uninstallation or anything else required.

👉 Click here to download the Portable version


The setup version comes with a setup file that you can run and it will install Uninstalr to your computer, it also creates a link in the Start Menu and Desktop to start the app and you can uninstall it from the Control Panel as you normally do with Windows apps.
👉 Click here to download the Setup version


Uninstalr works in Windows 11, Windows 10, Windows 8 and Windows 7. The size of the portable version is just 5.5 MB.


If you are unsure which version to download, you should download the Setup version.



When you buy a hammer, it probably comes with a warning label saying that you should not hit your finger with it. Anyway, this is the same kind of warning:

Before uninstalling anything, always follow the on-screen instructions within the software and carefully review all the data that Uninstalr says it will remove if you proceed with the uninstallation. Always create a backup before uninstalling anything. Only uninstall software you know you want to fully remove.



PS. I understand the included translations are not the best. They are mostly automatically generated. I can’t afford to hire professional translators to create and maintain dozens of translations for a free software. I can barely afford to keep the lights on in my office (read: my basement). If you want to help with the translations, please download this Zip file , open the translation file of your language with any text editor such as Notepad++, locate the [custom_strings_uninstaller] section and edit any poorly translated texts from there. After you are done, send me the updated translation file and I will include it to the next released version of the program. Thanks!



 

Change Log

Improvement: The program can now better detect portable apps stored in the system.
Improvement: Greatly improved the analysis and detection of Steam games. For example, sometimes a Steam game installation would show only a few KB installation size, when the actual size was much higher.
Improvement: The program can now better handle files stored in the user’s Documents folders. Sometimes this folder contains only documents, as the name suggests, but sometimes installed apps also add their files in there.
Improvement: Comes with updated Swedish translation. If you want to improve the translation of the program in your language, please download this file: https://jv16powertools.com/downloads/TranslationHelper.zip, open the translation file of your language with any text editor such as Notepad++, locate the [custom_strings_uninstaller] section and edit any poorly translated texts from there. After you are done, you can send the updated file to me via https://uninstalr.com/TranslationsSupport and it will be included to the next released version of the program.

Fix: The program fails to detect the installation of certain Steam games, for example, Goose Goose Duck.
Fix: The program can list some Steam games twice, such as Quake Champions.
Fix: Ctr-clicking Show App Types > Platform: Steam would also check the Chocolatey App type, and vice versa.
Fix: The program can sometimes list specific type of installed software more than one time, for example, Backup4All. Note: Not all duplicate listings of installed apps are incorrect. For example, if you install Skype from Microsoft Store and then from their website as a standalone app installer, you will end up with two instances of Skype installed, and listing them twice is correct and expected with Uninstalr.

Known issues: The default installed software scan is slow in cases of a lot of installed software. For example, if you have over 200 installed software, the default installed software scan is probably going to take a few minutes. In such case, you can change the scan setting from the Settings view for the program to start faster.
Known issues: The program doesn’t fully support screen readers.

New feature: Added improved searching, filtering and sorting options to the installed software list.
New feature: You can now choose the leftover scanning mode. For example, to use Uninstalr to only batch uninstall software by automating the running of each app’s own uninstaller, but without any additional leftover data cleaning.
New feature: You can now choose the installed software analysis depth.
New feature: You can now skip the main analysis to quickly see the main program window, for example, if you just want to use the new software installation monitor.
New feature: Uninstalr can now detect and uninstall PortableApps.com apps.
New feature: Uninstalr will now attempt to create a System Restore Point before the uninstallation begins.
New feature: Uninstalr can now detect and fix incorrect information from the Windows installed apps list, such as incorrect installed app sizes.

Improvement: Greatly improved the accuracy of installed software, portable apps and leftover detection.
Improvement: The installed software scan is now faster on most systems. In systems with a lot of software, the scan can still be fairly slow.
Improvement: The program is now much better in detecting cases when user attempts to uninstall something that might be dangerous. In such case, an additional confirmation message is shown to the user.
Improvement: Starting to type anywhere within the main results view will now add these key presses to the search input box. Previously, the search input box had to be in focus for this to work.
Improvement: You can now start uninstallation by selecting an app from the list and hitting the DEL key from your keyboard.
Improvement: Pressing ESC can now be used to close elements within the program, for example, ESC will now clear any active search filter. If you want to close the program itself, a Shift+ESC press is required. This is to avoid accidentally closing the program while working with it without using mouse.
Improvement: The rows of the selected apps are now highlighted to make it more clear what is selected.
Improvement: The Show All Data view now also includes a search feature, allowing you to quickly see whether the list contains any paths matching your search term.
Improvement: Hitting the Home key from the keyboard now takes you back to the list of installed software.
Improvement: Starting the uninstallation will now better communicate to the user that the system will be restarted during the process, if that option is checked.

Fix: In some rare cases, the software could get confused with paths of software with similar names and also list such paths to be removed as well.
Fix: When uninstalling software, Uninstalr can fail to automatically close browser popup if you are using Edge browser.
Fix: The default sort order of the result list was quite random. Now the default sort is based on the software name, and it's also easy for the user to view the current sorting method and change it.
Fix: The Don’t Show Builtin Windows apps filter could sometimes hide third party apps if their names sounded similar to builtin Windows apps. For example, if you have an app called Notepadify installed, it could have been incorrectly classified as a Builtin Windows app, because it sounds like Notepad.
Fix: Right Click menu’s Settings option was visible also when the Settings view is already open.
Fix: Maximizing the program window could cause it to go over the Windows task bar.
Fix: The installation date can be different than what is shown in Windows Settings > Installed Apps.

Known issues: The default installed software scan is slow in cases of a lot of installed software. For example, if you have over 200 installed software, the default installed software scan is probably going to take a few minutes. In such case, you can change the scan setting from the Settings view for the program to start faster.
Known issues: The program doesn’t fully support screen readers.

Improvement: Added Uninstall to the Right Click menu, and you can now uninstall a single app by simply performing Right Click > Uninstall with it.

Improvement: Microsoft Store apps are now detected better. Previously their name or publisher data could be partially incorrect or missing.

Improvement: Added an option to the Settings page for user to choose the level of leftover data scanning. With this setting, it’s now possible to use Uninstalr to only run and automate the uninstallers of the apps that are being removed and without any additional leftover data removal.

Improvement: Portable app and leftover app detection is now more accurate.

Improvement: The distinction between Show All Data and Uninstall views is now better. The Show All Data view no longer displays the Uninstall button, either.

Improvement: The program now uses less RAM to operate. In some systems, the program might fail to start because of Out Of Memory error. This issue is not yet fully fixed, but it should now occur be even more rare.

Improvement: The Uninstallation data view now shows a tip explaining that the view might contain non-existing paths. This is done, because sometimes running an app’s uninstaller actually creates new data to the system. By listing non-existing paths, these paths will also be removed during the uninstallation.

Improvement: The installed software analysis should now work faster on most systems.

Fix: Changing the user interface language and then clicking Save Settings doesn’t always work. That is, the newly changed language setting is not saved.

Fix: In some cases, uninstalling any app could cause Windows to display Blue Screen of Death error message and reboot. This was entirely a cosmetic issue, there was no data loss or damage to the system.

Fix: The program assumes that Windows PowerShell is installed in the system and available. If it’s not, an error message was shown in such systems. This is now fixed and the program no longer assume that PowerShell is available.
