@schmidthouse, if the trouble shooter doesn't resolve your updating issue " which I doubt it will " as there has been numerous issues lately with a number of Win10 updates getting stuck at a certain percentage and the only option that has fixed it for me on 3 of my systems so far is as below.
Step :1
a. Press Windows Key + X.
b. Click on ‘Command Prompt (Admin)
Click ‘Yes’ if it prompts for UAC(User Account Control).
c. copy/paste the following commands into the command prompt one after the other and press enter after each command
net stop wuauserv
net stop bits
net stop cryptsvc
Keep Command Prompt window opened.
Step :2
Rename Windows Update folders
At the command prompt, copy/paste the following commands, and then press enter after each command:
ren %systemroot%\System32\Catroot2 Catroot2.old
ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
Then copy/paste the following commands and press enter after each command:
net start wuauserv
net start bits
net start cryptsvc
Once that is done close the command window and retry the Windows update
Note! once the windows updates have gone through you can navigate to the two renamed "OLD" folders and delete them
