I have the same problem within minutes of Updating on the 26 of December 2024. Thought I'd wait for better times. Usually later things are better. Well are they?
Aparantely one can recover to the last Update by going to
Windows
Settings>System>Recovery>
Recovery Options>Go Back
But I am not sure if it searches for a back up one makes or a Windows Instalations backup.
I also do not know if it starts immediately without explaing the procedure, and this could be an issue if one has not made any Backups.
I personally stoped doing back ups a long time ago in other versions because I have organised my Computer in such a way that I can recover most things.
Only this time due to the new arquitecture of Windows 11, and lack of space I have been delaying things. So I just lost a whole bunch of very important copies of health Files, from Xrays, CAT, Medical Certificates, personal documents, Invoices. A nightmare.
If you are lucky with this procedure please report. Thank you.
