I have not tried this myself, but it is said to disable Windows Updates (you would have to manually do security updates)
From this link:

Go to HKEY_LOCAL_MACHINE SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\AUOptions .... If you set AUOptions to “1”, Windows 10 will never check for updates.
Note: Belarc Advisor will find all your installed programs and license codes. You will of course, need the software for the versions you are installing to be on hand. You might want to make an Image of the existing Win 10 install in case you need to restore back to it.
You can also try this:
Restore and repair system files. Select the Start button, then in the search box on the taskbar, type
command prompt. Choose
Command Prompt from the list of results. In the window that pops up, type
DISM.exe /Online /Cleanup-image /Restorehealth and press the Enter key.
