No kidding!
Thanks for the updated bad KB's - My quash list is up to a dozen now. Just to keep FS running smoothly.
But.... It seems that MS wants to get their paws on your system anyway they can. The other night I was flying along nicely until stutters started, looked at the blinky light and it was flashing away.. Something was seriously accessing the drives. I paused the flight and started resource monitor to see what was doing all the accessing.
MsMpSvc (MS anti-maleware service / MS security essentials) had started MRT.exe (Malicious Software Removal Tool) . Here's the kicker. In MS security essentials I turn off "real time" monitoring during FS sessions and I have it set to manual scanning (no schedules). In Windows update I have it set to "Check but let me choose...." . I checked the timestamp of MRT which showed it was the newest - I didn't download it yet! - And it is still in the update queue! It seems that these 2 system tools don't follow the settings that I provide! I'm now stopping the update service during FS sessions, cannot stop MsMSvc though, they start that one with such high credentials it is impossible to stop.
Looking into scheduled tasks ( or try to stop service during FS sessions ) now to see if there's something in there. My little Low-Mid powered PC cannot handle such nonsense while FSX is up.

Edit - MRT is a fall back if MsMpSvc fails - Windows logs show no such failure although the time it happened was right around the time of a scheduled scan.... If it was enabled... MMMM ???
