I was working on my computer with a client today, helping him set up an account, when Windows 10 decided that it was time to install a stack of important updates, and then to reboot in order to complete the installation. It gave me no warning of what it was doing, the screen simply went black. I fought with the computer for about ten minutes, during which time it rebooted a couple of times and finally gave me a message saying that it was finishing installing the updates.
Why couldn't it tell me that earlier? Why couldn't it advise me that it had some updates to make, and ask if now was a good time to download and install them? Windows 7 used to do that.
Actually, I had to go into the Control Panel in Windows 7 and change the settings so that it would behave politely. It used to be just as rude as Windows 10.
So as soon as Windows 10 finished updating, I went into the Control Panel and changed its settings. Windows 10 won't allow me to postpone downloading the updates, but at least it will ask my permission before it iinstalls them. The Windows 10 Control Panel warned me that it was recommended that I allow Windows 10 to download and install updates whenever the hell it wanted to.
Not after today's experience, Microsoft. You locked me out of my computer for ten minutes, when I was in the middle of a critical task. You no longer get that control over me. And if you try a sneaky stunt like that again, I will stop using any Microsoft product: Windows, Office, you name it, it won't be on this computer.
UPDATE: It can be hacked to allow you to disable the automatic downloads as well. Here's how.
UPDATE 2: I followed through on my threat. This PC doesn't have MS Office on it - no Word, Excel, PowerPoint or Outlook. I'm doing just fine, thank you.
