I see this problem here and in so many blogs.
Several things are very wrong about current Windows 10 updates.
[Note: I am a tech and have worked with Microsoft programs for 30 years]
They happen even when I am in the middle of active work. I was editing a book and the update loaded and restarted the computer, and did not recover the book. [Yes, I had a back up]
They happen even if I do not want them. You cannot turn off updates. I turned them off in services and the registry and Windows turned them back on again.
They do changes that I do not want. I want immediate access to the standard control panel, the update removes that. [and other things]
The updates change my desktop icons, and my Start Up screen. It would take me over an hour after each update to correct my desktop and Start menu. [I don't do that, I reverted]
After reverting several times, Windows will not allow reversion. I only reverted once. After that, when the update starts, I just immediately restart my computer. That forces the update to wait one day.
Finally, I disabled Windows Update [bad, because I would like some updates] in the registry. I disabled it in Services. Then I blocked windows update in my firewall device. So now updates cannot even download at all.
So that works for now. But it is sad that all of this is necessary. Apple updates my iMac [s] regularly without failure. It asked me, when finished, if everything is okay. Once [two+ years ago] there was a problem and the Apple update reverted on its own.
Then reinstalled properly by itself at a later date [and works fine.]
Microsoft just cannot get it together on this.
Another note: My machine is a new[ish] Dell Precision. Latest processor and hardware etc. No reason that anything should not work. But the Windows 10 updates have crashed my system and caused problems EVERY time it updates for the last six month.
