If you google you can see it is a known bug that Chrome _can_ make your computer crash if you mess with the pagefile.
It is completely possible that the Windows store rolled back your update or fix to solve the chrome issue - bringing back the initially fault with your computer crashing with the DJM900. All in all it seems like the pagefil fix is, as mentioned earlier, a way "peeing in your pants to keep warm at winther"
I have played out 2 nights, using CDJ's as soundcard but with the 900 connected. No issues what so ever. I will try this friday again but with the 900 as soundcard even though i must say i am a bit worried about it still.
