Speed up Windows 10 installations
 

Two steps to speed up Windows 10 installation:

1- Disable Microsoft Malware Protection;

* Settings --> Update & Security --> Windows Defender --> Turn Off "Real-time protection"

Or run:
%ProgramFiles%\Windows Defender\MSASCui.ex
and from the settings disable the Defender.

Or:

* Run "gpedit.msc" Group Policy Editor,
* Navigate to Computer Configuration --> Administrative Templates --> Windows Components --> Windows Defender
* Double click on "Turn off Windows Defender" and Select "Enabled" --> Apply --> OK
* Close Group Policy Editor

When finished, enable Windows Defender by resetting it back to "Not Configured" and restart the computer..

2- Raise Priority to High;

* Start Task Manager and Right click on the Setup process, Click on "Go to details", right click on the executable and click on "Set priority", choose High (or any setting higher than Normal).

This should bring down the installation time from hours to minutes..
