Uninstalr is a relatively new free and powerful uninstaller with a portable version available.
We are already spoilt for choice with uninstallers but I thought I’d take a look at this new offering anyway and was suitably impressed.
Uninstalr Download & Usage
Uninstalr is available in both installable and portable versions. The portable version consists of a single executable weighing in at a mere 4.00MB and it’s the portable version I’ll be looking at.
- Batch uninstall many apps at the same time
- Supports unattended uninstallation of apps
- Supports monitoring of new software installations
- Also detects portable apps and previously uninstalled software leftovers
- Shows all the data added to your system by installed software on a file-by-file basis
- Shows all the data it will remove before starting the uninstallation
- Filter and search the list of installed software
- Supports detection and uninstallation of Microsoft Store, Steam, Big Fish Game System, Chocolatey, NuGet, and Ninite installed software
Uninstalr is a no-nonsense but feature-rich uninstaller that does just one job but does that one job extremely well. Where Uninstalr excels is in identifying and deleting leftover remnants. It achieves this in part by deleting all remnants following a system restart.
This behavior makes perfect sense to me as some files might be locked and can only be deleted following a restart. Think stubborn-file removers such as Unlocker and ThisIsMyFile, these types of tools almost always delete those stubborn files following a system restart. As far as I am aware, Uninstalr is the only free uninstaller that includes a system restart to properly complete the process.
An image on the Uninstalr website displays the results of in-house testing with comparisons between popular uninstallers of how effectively they each deal with leftover remnants:
Those numbers might seem a bit extreme but there is a video included on the Uninstalr Home Page which explains the testing procedure. I also tested Uninstalr in a Windows 10 VM and it did indeed delete more remnants than any of the main free alternatives (Revo Free, Geek Free, and HiBit).
I must point out that my testing was far from exhaustive, involving only a single uninstall. Quite frankly, the job of manually searching for leftover remnants in both the registry and file system after each of the four uninstallers has completed the process is a laborious time-consuming job. Still, even the result of that single test was positive.

Uninstalr ticks a lot of boxes. It’s free with a portable version available. Supports batch uninstall and installation monitoring. It’s lightweight and, according to my limited testing, extremely effective. If you’re looking for a no-nonsense, feature-rich, lightweight, and effective uninstaller, you should definitely check out Uninstalr.
