Just a reminder as the5th gets closer. When I upgraded from win10 to Win 11 it allowed me 10 days to roll back to my old OS if 11 didn't work. The number of days can be changed with DISM (unless MS has changed it) It could be changed to around 30 rather than 10 but you cannot set it for too many days.
To change the number of rollback days, use cmd prompt as administrator and type:

DISM /Online /Get-OSUninstallWindow

to Increase number of days to 30 Type:

DISM /Online /Set-OSUninstallWindow /Value:30

then type DISM /Online /Get-OSUninstallWindow to check that the new value has been accepted.

Obviously a lot of you will know this but it may help some people just upgrading from 10 to 11.

I hope this still works
