Should I leave Windows 11 Pro 26H2 Desktop on with internet until tomorrow 13 November? Should I leave EDGE open and SYNC ON?
Managing profiles and sync in Microsoft Edge on Windows 10
You don't need to leave your computer turned on overnight or keep Microsoft Edge open just to maintain sync. Edge Sync works in the background as long as you're signed in and sync is enabled.
I recommend checking that Edge Sync is turned on under Settings > Profiles > Sync. You can then safely shut down your computer and resume using it tomorrow.
Just to clarify, are you waiting for a specific Microsoft service or synchronization issue to be resolved by November 13? If so, leaving your PC on will not necessarily speed up the restoration.
