once I follow the instruction to restart, I am still sent back to the beginning and, for my tablet, many of the suggestions are not workable
Then for better help you should open your own thread with your own details. Otherwise, "tablet" suggests a possible lack of freespace and then for that circumstance users are being advised to temporarily attach something that gives them more freespace.
I'm not sure if it has been made clear anywhere in this thread (or the other one you posted to) but the code is not indicative of a problem
PS>net helpmsg (0xbc2)
The requested operation is successful. Changes will not be effective until the system is rebooted.
If there is a problem after a restart which causes the update to have to be retried it usually is due to interference during the apply phase. For that cause users are advised to at least disable but preferably uninstall any possible interferers.
So, you should be trying to provide a clearer more complete symptom description of your particular case. For example, what "suggestions are not workable"?
