Help Uninstalling Sims 1 on Windows 10!!

@blingerlove  Yeah, the forums can be a bit of a maze to navigate the first few times you show up.  That's why we can move posts—quite a lot of them end up in a different section than the one that corresponds to their game.

Anyway, sorry no one has responded to you yet.  Sims 1 is so old I'm not actually sure of the best way to uninstall it.  But a good place to start would be Revo Uninstaller (the free version is fine), which usually does a good job of cleaning up both the program files and whatever leftover remnants remain elsewhere on the computer.  You don't even have to install Revo if you'd rather not; just pick the portable version.

Let me know if you need instructions on how to use it.

If Revo doesn't work, or if you want to make sure it was thorough, you can also try Piriform's CCleaner (again, the free version works fine).  That's the preferred tool for removing registry entries when you don't want to clean it yourself, always a dicey proposition.
