Windows 10: Cumulative update during business hours?

My PC (win 10 pro, 64bit) started a cumulative update at about 9am this morning and it's still cranking.
Is it really necessary to do that during business hours despite my business hours setup is from 8am to 8pm?
I remember, before the anniversary update, the updates started in the evening when I shut down my PC, went through its paces at night and shut the PC down when it was finished. What happened to that?
Thanks,
Ed

Trying to install Windows 10 - error code 0x80004005

Error 0x80004005 and update fails during windows 10 update. Specifically: Cumulative Update for Windows 10 for x64-based Systems (KB3093266)

Windows 10 setup will install the latest cumulative updates automatically, as long as you remain connected the Internet during installation.

 

Hi,
1. You can block Windows updates from downloading by various widely published means. The downloads otherwise occur at any time.
2. You can use Active Hours (build 1607) to prevent restarts during a 12 hr period max. You should be able to use 3rd party software to block restarts otherwise (I haven't managed to definitively test that with updates).
3. Pro upwards editions support deferring upgrades (in Settings).

 

Thanks for the quick response, I have checked "Defer Feature Updates".
My main reason is the restart. After any update, I have a heck of a time to restart my PC. I usually see a black screen with rotating white dots for hours. I have to cut power and restart a dozen times before the PC finally gets to its working state. It's a pain in the rear.

 

Hmm, have you run chkdsk c: /F ? Could be something else entirely of course... It's very poor that updates are causing so many issues- I never noticed that on Win 7 or 8 or earlier.

I had to try the current one twice- but the restart was no issue, nor has it ever been. But there's that uncomfortable lurking feeling your PC might not boot properly..

Best defence/preparation is to use disk imaging routinely. System Restore sometimes doesn't work when you want it to.

 

As I had mentioned, that restart issue started with the anniversary update.
Regular everyday starts in the morning are no problem at all, only after updates.

 

I was only referring to a restart after an update. It's worth running chkdsk- it's a routine thing.

It might also be that sthg you have installed has an impact in some way.

Analysis: bound to be time consuming. And tricky as you're only interested in a restart after an update.

I did that chkdsk thing a while ago and it did not yield anything.
I'll try that Windows Performance Recorder, if I can figure it out.
Thanks for your help.

Of course you can recreate the scenario- presumably- by uninstalling an update and repeating the update. For this purpose it may be convenient to have installation file for the update- see the relevant post for KBxxxxxxx in the News section here for a link (usually the first post)
