Just today on starting my Win 7 64 Pro that a small screen flashed quickly on and off and kept appearing, the warning was "Autoplay System Reserved (G: )everything was fine at shutdown the night before. G: drive is a flash drive and only connected when needed.
I checked error logs and could only find two errors around the startup time, TfFsMon and TfFvsMon whether these are relevant or not I have no idea!
I rebooted with the same problem. I then unticked 'Use Autoplay for all media devices' in Control Panel~Autoplay. Rebooted and all seems fine again.
I then tried a System Restore of a few days ago and this failed possibly due to my AV running, I turned the AV off until a 'Restart' and again tried a System Restore, same failure with unspecified error (0x80070005).
If I turn on Autoplay the problem re-appears, my PC slows and generally is not happy, turn off Autoplay and its fine.
Any suggestions as to what the problem is and how to fix it?
