Start Menu Corruption
I recently had a problem with Windows 10 x64 where the start menu would no longer respond. I checked the net and found that this was not an uncommon problem and then attempted many of the suggested fixes for it. Nothing worked. I finally had to just reinstall the whole OS.
One of the things that I noticed was that shortly before this occurred the desktop icons on my dual monitor set up had shifted from one monitor to the other. I ended up manually moving them back to the desired monitor and the problem appeared to be fixed. It's probably just a coincidence, but I wanted to check here to see if anyone else had experienced the same problem.
Thanks for your help,
Al
