Hi Cadence -
I'm Kevin B., I do apologize for the inconvenience that you're experiencing right now, let me help you sort things out.
Update sometimes takes time to complete especially if the updates are big or large updates. Interrupting the installation of windows updates might corrupt the operating system especially that the update is a firmware update.
Kindly try to wait a few more minutes for your computer until the update completes. If the update installation fails, the screen should give you a message or error message that the update fails to install.
Please do keep me posted once update completes
Hope this will help and have a bless day!
Thanks.
Kevin B.
