Hello All, yesterday I updated my W8.1 laptop to W10 so knew how to to handle certain problems having bought a new Desktop with W10 installed 2 months ago. This morning I noticed a new item on the This PC page, this being SYSTEM_DRV( G:) and consisting of a FAT32 256 MB capacity with 27.9 MB used and Acces Denied. I was able to scan the content with Avast free and although the files flashed by they were prefixed with "Microsoft Boot". Going back to yesterday the Action Center on booting up and restarting kept telling me that three components were not compatible and therefore uninstalled. Today it no longer declares this so I am wondering if the SYSTEM_DRV unit has rectified it.
