Installed on Windows 8.1 x64 with problems

Hey,

I downloaded Winant last night and tried executing with your app. It froze the computer and started acting strange, everything was unresponsive. So I had to hard boot. I've deleted the file. However now the computer feels very sluggish and slow. 

What did the app do, what processes did it add as I need to manually undo this mess!
