Thanks for your suggestions but it's to drastic for me? I need app popups in the lower right corner of windows 11.
The 'notification' I speak about is not a usual notification: it's not a popup window. It covers the whole screen and appears before it shows it shows the windows 11 desktop at boot...
Each time after a couple of days when I reboot I get a white screen with the request "Make a backup of your files".
The last item mentioned is "file changes will be updated automatically"
(sorry for the translation)
I do not to make a backup in onedrive because I make (incremental) image.
