Clearing Guide Data and Tuner Setup from WMC

There may come a time when you need to completely erase the history of your downloaded guide data and tuner setup. Something may have gone wrong with your setup, tuners may have changed or maybe you’re just looking to clean house a little. Don’t worry, this isn’t going to require a complete reinstall of Windows 7, the process is in fact quite easy. Windows 7 Media Center stores all the information we need to clear inside database files stored inside the ProgramData folder. However, we’ll need to close a few background services before we’re able to clear the files from the drive.
