Looks like MS are up to their old tricks... Need GWXI Control Panel !
On my new (well under 6 month old) W10 laptop, just received the first notification "Upgrade to Windows 11 is ready for your PC".
Need to find out if there is a Group policy setting that prevents the display and actioning the update.
Expect in the coming months to see the "Upgrade to WIndows 11" messages to become more intrusive.
