Updates

Roderunner · 26 Jan 2022

Hi Folks, today, I was doing updates, I had installed all but the last one, '2022-01 Cumulative Update Preview for Windows 10 Version 21H2 for x64-based Systems (KB5009596)'
It reached a point where I had to keep a prearranged appointment, so I left my laptop to continue doing its update. At that point it had reached 74% of installation, when I got back 3 hours later it was still at 74%. My laptop is programmed to turn off the display in 5 minutes. Why was the installation not done when display was off? I eventually completed it within 5 minutes.

Perhaps your laptop will go to sleep after X minutes of inactivity.

And besides that possibility, occasionally updates can appear to 'stick' at a certain %ge.

I choose not to allow preview updates.

I have never used 'Sleep' or 'Hibernate'. As updates occasionally tend to take a while, I do other things while waiting for the prompt to Restart.

Thank you for your reply. Then see above.

Run the following script and see whether the logs will provide some clues.

Unfortunately, I found no clues.

I normally go to https://www.catalog.update.microsoft.com/Home.aspx and type the KB number in the search box to see the size of the update to get a rough idea of how long it will take.
