I recently had to roll back a windows update that was severe enough that upon login, all I got was a black screen. The only means of doing _anything_ was to reboot into safe mode and rollback the latest windows update. Upon checking my "action center", I have the following problem report for the explorer process, which mentions something that looks like a window blinds exception being thrown:

I don't tend to run windows very often on this machine, and when I do, I tend to install a tonne of updates at once... so I'm not sure which one triggered this. The rollback claimed it was a "directx" update, but I know I installed many more than just that one.
