hello! i have used a tool to overcome win7 expiration, which as far as i can remember, it didnt change any system files, and it had an option to uninstall itself however i cant remember which was exactly can you help me please thanks!
Look at your C: drive for folders that look like a loader or some such. Of course this requires familiarity with your system but hopefully you have that. Go to the uninstall panel and see if any loaders are available to be uninstalled. Check your Download folder and see if you left a downloaded loader there. Basically you'll have to just look around to see what you can see.
