Don't worry, I'm going to contact Microsoft support about this tomorrow - they are surprisingly responsive - but since Jane started this thread, might as well throw this one in here.
Toshiba Satelite P50 laptop
Windows 8.1
Computer's been unable to install Windows updates since whenever the last one came through.
When it's time to restart I hit "update and restart".
The PC seems to go through all the steps for installing the updates, but then I get this message:
Error: We couldn’t complete the updates, Undoing changes. Don’t turn off your computer.
The PC then restarts normally with no issues, but the latest Windows updates have not installed. Been like this for more than a week.
No need to direct me to any Let Me Google That For You results. Just wondering if others w/ Windows 8.1 have experienced this and whether any of the (seemingly dozens) of solutions offered online worked for you.
