Uninstalr is a free Windows software uninstaller. You may download a portable version or installer from the developer website. It runs on Windows 7 and newer versions of Windows.
The application supports several features that are often only found in commercial uninstallers: monitor software installations, deep cleaning, batch removals of apps and support for a variety of software stores and distribution platforms.
Uninstalr: the basics

The Windows software uninstaller scans the system on start. This may take a moment, depending on the number of installed programs and the system’s performance.
The list includes installed programs but also leftovers from apps that were previously installed on the device.
Tip: open the program preferences first and uncheck the automatic system restart option after software uninstallations.
Each program is listed with its name, developer, size on disk and type. Filters at the top give you options to create custom lists. You may display only leftovers or only programs from Steam, among other options. Microsoft apps are hidden by default, but you may enable these as well.
Removing programs is easy. Select one or multiple of the listed apps with a left-click and activate the uninstall button afterwards. You may also select “show data” first. Show data lists all found locations, files, folders, and Registry, of the selected apps.
The program lists the information when you active the uninstall option. The removal deletes the programs entirely from the system. It is recommended to restart the Windows PC afterwards.
Core features of the Windows software uninstaller
Uninstalr’s core feature is the removal of one or multiple programs from Windows PCs. Additionally, it supports monitoring software installations for easier cleaning in the future.
Using the program is simple. Run it, wait for the scan to complete, and select apps to remove. This process worked well during tests.
I still recommended that you create a system backup of the main partition for safety reasons.
Besides cleaning leftovers from the Windows PC, you can also use it to find and uninstall large programs. Note that the sort options appear bugged at the time. The sort by size option did not work correctly during tests. It allows you to sort apps by size.
Select “New Software Monitoring” in the interface to monitor a software installation. The Windows software uninstaller monitors installs automatically at this point.
It lists the program when you run its installer. Note that this does not work for portable apps. Some installations were not detected by the application either while running. Still, you do benefit from the leftover scan option in any event.
Should you use Uninstalr immediately?
Should you use Uninstalr immediately to remove Windows programs, or the default Windows uninstaller first?
This depends. If you used uninstaller to monitor software installs, then you may use the program immediately for the removal. if you did not, use the Windows tool first and then Uninstalr to take care of leftovers.
You should not run into any issues removing apps with Uninstalr directly either.
Comparison to WinGetUI
WinGetUI is a user interface for winget. It allows you to install and uninstall Windows software. A core difference between the two apps is that WinGetUI does not scan for leftovers.
It is still useful, for instance for installing programs on Windows or removing bulk programs. After using it to remove apps, you may want to run Uninstalr to benefit from its leftover removal functionality.
Closing Words
Uninstalr is a powerful software uninstaller for Windows. The program is ideal for removing leftover files and Registry entries from already removed software installations or portable app installations.
