FYI.
KB 3022345 turned up on my Win7 Netbook, this morning. You get a bit fed up with MS Updates.
InfoWorld Woody Leonhard indicates, it's "to enable the Diagnostics Tracking Service" Win7.
When my Netbook reaches the end of it's technical shelf life; it's going to be retired. It won't be upgraded to the then, current O/S.
Just buy a brand new PC !
Be safe out there !
