How to change the number of days to revert to previous Windows Installation

Recently I got the question how to change the number of days for reverting Windows 10 to the previous Windows 10 version. Just in case e.g. your hardware or software is running into trouble. Default value is 10 days but this might be too less for strange issues comming up later.

In the web there are several ways to do it (like renaming the .old Folder etc.)

But the offical supported way is this one (problably set during a task sequence)

It is actually a DISM command.

Run this command against an online image to set the number of days after an upgrade that an uninstall can be initiated.
DISM /Online /Set-OSUninstallWindow /Value:<days>

Default is set to 10 days. Can be set between 2 – 60 days.
