Microsoft provides an official tool specifically designed to completely uninstall apps on windows 11 for those stubborn MSI installers. The tool works primarily by removing Windows Installer registry entries that interfere with the standard uninstallation process, thereby helping you completely remove problematic software from your system.

Search for “Windows Installer CleanUp Utility” in the Microsoft Download Center and download it. After opening the software, select the target program from the list and click “Remove.” Afterward, please manually delete the program's folder. It provides a fast and reliable solution for completely uninstall apps on windows 11, effectively removing stuck MSI-based programs from your system.

It is particularly useful for removing stubborn MSI-installed programs that won’t uninstall normally, fixing failed uninstallation issues, or cleaning up corrupted Windows Installer entries on Windows 11.

Cons

  • Outdated, traditional tool; no official updates for modern Windows 11
  • Only removes the installer's registry entries; program folders must be deleted manually
  • Works only with programs installed via MSI; not compatible with applications installed via EXE or from the Windows Store
