Sorry if this is the wrong place to ask this. My PC bought in March 2022 is showing in Windows 10 Update as 'eligible for Windows 11'. So far I have resisted the temptation, as I have a lot of stuff that I fear may be broken if I switch.
I know I can revert in within 10 days. If, before upgrading to Windows 11, I make a backup image of the disk, say with Macrium Reflect, and restore it later than 10 days after, am I likely to find the old Windows 10 install is now unlicensed?
