How to tell if peer.exe (Grid service) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files. Be sure to check the Registry as well for remnants of Grid service. To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for Grid service or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.

What to do if a program does not uninstall

The easiest way to remove any kind of software cleanly and accurately is to use an uninstaller tool. Because the uninstaller automatically creates a backup, there is no risk of anything going wrong.
