Hi Rebecca,

It is possible that a system file might have been damaged after an unsuccessful update. We have an article that can help you with this issue. What needs to be done is for you to do a system restore to your computer. Kindly visit the link provided here for more information: Recovery options in Windows 10.

If you think this was useful, you may "mark it as an answer" to help those who are facing the same problem.

Are you able to get to Task Manager from this screen?

CTRL + SHIFT + ESCAPE

or

CTRL + ALT + DELETE

If so, then try to open a command prompt with elevated privilege by doing the following:

Then type in to the command prompt
taskkill /im explorer.exe /f

then

explorer.exe

Hopefully it is just the process stuck at this point and it can kick off again.

Good luck.

That's a shame.
