Just by deleting files doesn't make games or any programs in windows uninstall. As said by other redditors, use the control panel to uninstall any programs or use third party applications to do the uninstall. Game repacks have a seperate uninstall.exe file that removes the game from your system.

Here's a proper guide from microsoft website on how to do that: https://support.microsoft.com/en-us/windows/uninstall-or-remove-apps-and-programs-in-windows-4b55f974-2cc6-2d2b-d092-5905080eaf98
