My daughter had a laptop about two years ago - HP ProBook 6475b - that she replaced with a high power gaming laptop.
My wife wanted to use it to run some old games, so I wiped it and restored the original build from the recovery partition.
It's totally FUBAR.
The first time she logged in as her MS user and it didn't work, so I wiped and reinstalled again and created a local user. Still doesn't work.
The problem is that it won't open anything. Edge starts to open then closes. Win10 settings won't open at all. The tiles on the start menu are empty. It's like the whole Win10 UI overlay isn't working. I think it's trying to download updates, but isn't succeeding.
I tried stopping restarting the Windows Update Service and that didn't fix it.
