I have a Windows 7 64-bit machine (Thinkpad). I updated Windows yesterday and after a restart, explorer crashes instantly. I've tried many of the hints given on forums like file system check etc. but it hasn't helped. Also tried removing the updates but unfortunately, it didn't help.
I've tried both sfc /scannow (system file check) & clean start up but it didn't help. What worked for me was this :
What specifically did you update? You ran Microsoft updates?
Boot into safe mode and see if it still happens. While there run
at a command prompt to make sure all your Windows files are not corrupt. You can also run msconfig>services>Hide all Microsoft services and disable all non-Microsoft services, then go to msconfig>startup and disable everything there. Boot back into normal mode with all those disabled. If it runs, reenable them all until the culprit exposes itself, and then repair or update that program.
If all this fails, and it did start happening after doing a Microsoft update, call Microsoft for free hot-fix support: (800) 936-4900.
