Slow Git operations in Visual Studio 2017

I have encountered a situation when every Git operation in the Visual Studio 2017 version 15.9.x in Windows 7 machine is slow.
For example: Checking out to a different branch, clicking on 'Changes', 'Sync', Fetch, Pull take time.
But, if you do these operations via command line,
all works fast.
In my case, clearing the AppData Visual Studio folder helped. Run %appdata%, delete or rename the 'Visual Studio' folder.
