Whenever I uninstall programs from Windows 7 Home Edition 64-bit, there is garbage in Windows Registry as well as leftover folders and files. I have CCleaner but it doesn't remove everything. I can't do clean reinstallation of Windows 7 Home Edition 64-bit right now. I have a weird problem with a driving simulator. I tried uninstalling and reinstalling the driving simulator but I still have problems. The driving simulator doesn't respond to a few key presses and button presses. Any suggestions?
