Post subject:	ClassicShell randomly hangs Explorer on Win10
I'm finding that Explorer hangs on Win10, perhaps once a day. When this happens, I can't click on the task bar or desktop or start menu. The workaround is to use the task manager to kill explorer.exe and then restart it. I ran a procdump on explorer after it hung, then used WinDbg to look at the threads, and found this thread to be the most interesting. Any ideas on the next step? . 3 Id: 6fac.4fc8 Suspend: 0 Teb: 00000000`0035e000 Unfrozen Start:
