Wireshark hanging on Windows 8.1 at startup

After upgrading Windows 8 to Windows 8.1 my wireshark freezed on every startup without showing up the main window.
The only workaround was to deinstall wireshark including wincap and installing it again. But after the nex reboot, it freezed again.

After searching around i found the following fix, with cured this problem:

inside the registry you have to change the DWORD start in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\npf

from 0 or 1 to 2. After that wireshark will start properly even after reboots....

Another possible solution are to issue these commands as administrator:
sc start npf
sc config npf start= delayed-auto
