TLB freezes under Windows 8

I've double checked the TLB code for apps executing - it is clear. Maybe something wrong in system?

Please can you check the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ShellExecuteHooks

Usually this key is empty. If you see any values in this registry key, this can be the point of the problems.

Also what type of items cause the bug? Is this shortcuts or documents in the Virtual Folders?
