Help 6 week of please do not power off or unplug your machine .... installing update 1 of 3 help .

Hello alenpyzer,

Welcome to the Community,

I have a couple of suggestions and maybe one of our other members can assist.

What OS are you running? Try this below,

Step 1: If it is still stuck on installing update page, then restart the computer and choose boot normally and check what happens.
If you get into Windows and not all of the updates were installed, then you can install the updates one at a time and see if one of them is having a problem.
Step 2: If you are not able to boot normally to the desktop, then you may use System Restore.

Please let us now how this is going and we can assist you more.

@ do you have any suggestions?

Best Regards,

Sherry, 
 
I think you have it covered.  While we all see this warning during Windows updates, and it really IS there for a reason (Bad things can happen if you turn off the machine when this is displayed), sometimes things go wrong anyway.  (Don't worry, I do not mean you did something wrong... you didn't!)
 
Usually, even on a very slow computer, if this screen has been visible for an hour, or two hours at the most, something has gone wrong with the update.  The only thing that can be done is what Shery has outlined above.  Sometimes things will end up OK, sometimes not.  
 
One thing that does sometimes happen is that after the forced reboot, Windows Update sometimes detects that there was a problem, and automatically rolls back to the system state prior to the update. 
 
Do be careful about doing a system restore: you will want to be sure that you are only going back to the previous restore point, NOT a full 'fresh from the factory' condition.  All of your data will be lost if you do a 'factory reset'.
