OT: Brief help with this computer problem?

[onomastikon]

Thank you.

I can find the folder (under /ubisoft) without a problem, there is no setup or uninstall icon there, only a game.exe.

I can click on the folder and hit "delete" -- but I thought that uninstallation is a much different process, involving registry data and all of that? If I simply hit "delete", wont I be leaving the program on my computer, wont it still be in my "software" properties without hope of me ever getting rid of it?

Thank you very much, oh computer-smart people
