Randomly, (Every 20 minutes) while navigating through Windows Explorer I will get a message that says Windows Explorer is not responding and I get an option to either wait or close now. When I choose to close now, I can not open windows explorer again for about 10 minutes. Each attempt results in a Remote Procedure Call Failed and Did Not Execute.
I began to encounter this error after installing a few programs coming from a clean install of Windows 7.
EDIT: I already went into services and confirmed my RPC settings. Would a repair installation wipe all of the programs I installed? Would this be a legitimate solution to this very frustrating issue?
