exactly! I can confirm it. This is a screenshot from SysInternals' Process
You can see that it hanged for about 30 seconds trying to open the file
"\\HEAD\PIPE\wkssvc" which obviously failed with the BAD NETWORK PATH error.
On my system, it always hangs for the same amount time, it's most likely a
It just suddenly started to happen (I have a Git status in my prompt so I
