We have been dealing with an issue related to our Windows 10 computers hanging at login. Sometimes it sits for 10 or 15 minutes before they are logged in fully. The login process sits at a black screen with a box at the top left corner that says "personalized settings".
After some research we have found that if you delete a couple registry keys it temporarily fixes the issue until the next round of Windows updates comes out. And it often happens again even to machines that we deleted the registry keys on. We have a method to temporarily fix this problem for people, but what we really want to know is what is causing this in the first place? I tried creating a new image for our machines from scratch after the Windows 10 1909 update came out but it still seems to happen to some (but not all) of our machines.
Anyone have any thoughts to the root cause? Something is problematic with Windows explorer, but we have no idea what is interacting negatively with it. Not sure if a bad Group Policy Object, or our AV. Not sure at all. All suggestions welcome.
Which registry entries? Deleted from where?
