My Win7 x64 crashed yesterday and today (twice altogether). In both cases minidump analysis reported: "Probably caused by : ntoskrnl.exe ( nt+71f00 )" In my opinion the problem should be attributed to one of the updates I have installed, however, I have no idea which one. I'm posting some screen shots which show my list of updates. In these screenshots you can see that finally all my updates succeeded, some of them only at the second or third attempt. The update we should look for is before the 18th since I installed the last six updates after the first crash. Could you please help me find out which update is to blame for this? Thank you.
