Note: open Command Prompt by right click on that and click on "Run as administration".

To turn Hypervisor off, run this from Command Prompt (Admin) (Windows+X):

bcdedit /set hypervisorlaunchtype off

and reboot your computer. To turn it back on again, run:

bcdedit /set hypervisorlaunchtype on

If you receive "The integer data is not valid as specified", try:

bcdedit /set hypervisorlaunchtype auto

Important note: after turning off the Hypervisor and restarting the system it is mandatory to turn on the Hypervisor because with out Hypervisor you can not use the git repository on your windows.
