I have problems with sandbox when i ran it it freezes my pc so i must to reboot my pc.I even try to reset sandbox and actually reinstall cis but it didn’t help so it would be nice if you will help me or fix it.Maybe this will give you some information the 9 sandboxed file that must run is dllhost.exe so it just kill and return back to 8 and freeze my pc.

Are you SURE you wree frozen? A decent sign that you’re frozen is when pressing CAPS LOCK doesn’t change the LED on the keyboard; then you’re frozen.

Ctl-Alt-Esc sorted by CPU is a good way to see what’s going on.
