My pal Hans has a strange problem on his newish Win 7 PC, with Explorer crashing. It's only been happening for the past couple of weeks. It may be associated with a software update: there's no way of knowing that for sure since he didn't realise for a while what was happening.
The symptom is fairly simple: if he opens explorer and right-clicks on any drive letter (the way you might check what percentage of the drive is full), explorer will close, an error message appear saying so, and the desktop will clear. After a few seconds, the desktop returns and the machine is back to normal until he tries explorer again.
We tried sfc /scannow which found a batch of several weeks' worth of updates that hadn't completed. It fixed those and reported "all resolved". The explorer crashed the second time we tried a right-click after that. Another sfc /scannow reported no errors found.
Explorer started from the icon on the desktop crashed every time we did the right-click. I tried starting from the start menu: and it worked OK once, then crashed every time thereafter.
I tried to boot into Safe Mode to see what that would reveal. The machine went instead into "Repair Mode" and chuntered for a very long time before restarting normally. Explorer crashed the first time we tried a right-click.
I created a new desktop icon with Explorer set to "Run with Admin privileges", and it seems to work OK every time at the moment. I fear it may be a matter of time...
We spent a fair old while with Google, looking at similar experiences with the same error number and message, back into the distant past. Only one matched our symptoms closely, and that thread ended inconclusively some years ago.
I'm hoping the kludge of running Explorer in Admin mode will work, but would prefer to fix it. Has anyone come across this, or has anyone any ideas?
This is the message from the error log:
