Hi, I don't know if this is helpfull but let me tell: Windows 11 Guest was painfull slow after Updating. I tried to go back with my snapshots. At least I reached the first one - a fresh installed Win11. I could do a update without problems. But: "a snapshot later" (40 Minutes later to the very first one): Win11 goes slow down again. My guess: KB5027231 from 2023-06. I could remove it on two snapshots and Win11 was ok again. Try this: Try NOT to get Win11 Update KB 5027231 (Disable Internet or use a update blocker (sordum tools) OR: Try to deinstall it. And let me know (Looking for confirmation)
