Hi, @Beth Seif
How long has the update been stuck on the same screen or percentage?
Also, what exactly does the screen say, and are the spinning dots still moving?
If it has only been a short time, I would leave the computer connected to power and give the update more time. Some Windows updates can appear stuck while they are still working.
For now, avoid repeatedly forcing the computer off. Interrupting an update can sometimes leave Windows unable to start properly.
Please let me know how long it has been stuck and what percentage or message you see.
Thanks!
