7 best uninstallers [Cheat sheet]

We’ve already covered what is uninstaller software, why and how to use it, as well as summarized information about 20+ best uninstallers, so you don’t have to look it up. These third party tools with the sole functionality – to effectively remove programs from computer – could be of great help. Our initial selection was based on user popularity, reputation and Google Trends. Then we conducted testing of each software and determined the 7 best uninstallers.

7 best uninstallers

Methodology. We’ve performed tests on a Windows 7 Ultimate x64 laptop. Tests included CPU loads, speed and efficiency, system “before” and “after” snapshots. Narrowing down one by one, we’ve ended up with seven products for Windows: IObit Uninstaller, CCleaner, Revo Uninstaller, Advanced Uninstaller Pro, BCUninstaller, Slim Computer, ZSoft Uninstaller. Let’s revisit each of them briefly.  

Uninstaller by IObit stands out by the fact that it is integrated into Windows Explorer and appears in the right-click context menu. This saves time and effort. If we open the program, we can view all installed  apps, search or filter by size/date/frequency of use. Delete apps one by one or select all. There is an option to create a restore point before uninstalling a program. In Pro version there’s the “Remove stubborn programs” feature – good for apps that reappear after computer restart, or continue with annoying promotions.

BC in the title stands for “bulk crap”, which is self-explanatory. BCUninstaller is for power users mostly, as developers claim. First time launch leads to a user guide, which is uncommon for uninstaller software. Also, many settings and features does not appear to be user-friendly. Setup includes user program selection (y/n), show apps marked as “system components” (y/n), apps marked as protected. In terms of performance, it is capable of removing programs with corrupt or missing uninstallers. It cleans leftover files, analyses and cleans local drives, exports a list of apps. Bottom line: good, but complicated for casual users.

This one is not just an uninstaller but a system optimization tool. Yes, it has no tools such as browser management, registry fix, duplicates detection, local drive optimization; however it is a robust hard-working uninstaller, capable of removing programs and malware that other tools cannot.

Tests and conclusion

We have summarized our testing results in a table below for easy comparison. Note that we measured average loads on CPU and RAM while running each program in the background (during uninstallation process the load could go up to 40-50%). In terms of toughest uninstall issues, Revo Uninstaller in its “hunter mode” proved to be the most effective.

It is also worth mentioning that none of uninstallers will remove 100% of traces and junk files, though much less will be left. As for the “free vs pro” issue – for home use a free uninstaller will be quite enough, while paid versions provide advanced scanning algorithms and will suite users dealing with software installation on a regular basis. Also, often cleaner software, optimization software and uninstaller software are thrown together as the same or similar tools, say CCleaner. Although uninstallers mainly follow these stages: scanning, restore point, deinstallation, registry and file system scanning, removal of traces.
