Hello, Same problem here. Medion p5220d-md8816 works ok but since a few weeks every other day the pc isn't functional the first 20 minutes or so because windows is reverting changes due to failed update of KB4535680. Error code 800F0922. This page seems to suggest a solution may be ready by half april. "Naar schatting half april is er een oplossing beschikbaar voor de resterende ondersteunde versies van Windows." The German version of the page (change language in bottom left) doesn't mention this. https://support.microsoft.com/nl-nl/topic/kb4535680-beveiligingsupdate-voor-secure-boot-dbx-12-januari-2021-f08c6b00-a850-e595-6147-d0c32ead81e2 Friendly greetings, Bram.
