Hi all, today my friend powered on her PC and had this problem where it doesn't boot to desktop and is just a black screen with a box saying "Personalised settings (not responding)". It seems to be a somewhat common after a windows update, however we're not sure what update caused it as we don't know how to check. We looked online to see how to solve the issue and found that even if we used ctrl+alt+delete to select task manager it doesn't open at all. Tried booting in safe mode and using command "DISM /Online /Cleanup-Image /RestoreHealth " in command prompt in many different forms but it always shows up as an error 87. Unsure what to do next as there don't seem to be many solutions that don't use task manager. Help is greatly appreciated, thank you.
