Since the issue is clearly Microsoft's lack of concern over burning through folk's data plans (because users aren't important) I think I need to define what time of day an automatic download is permitted.
Trouble is that so far I find that the only suggestion to stop MS taking over control of one's personal computer as if they owned it, and had any right to do so, is to define the Internet connection as metered.
Problem is (and I shall carry on searching after posting this) the instructions I find on the Net to accomplish this, are flawed. They say to first so to Start / Settings / Network & Internet / Wi-Fi / your connection name: but as anyone who follows that will be able to see, there is no Start / Settings / Network & Internet / Wi-Fi.
On the Network & Internet screen all we see are Status, Ethernet, Dial-up, VPN, Data usage, and Proxy down the left hand side. There are links in the right had pane but none look likely to be the one.
I'm finding loads of screens and changeable things but nothing I feel confident is going to achieve what I wish, and not going to cause an issue when I'm not around to try to fix it.
Anyone any thoughts on how to make the normal Ethernet connection to the ISP a metered one ? If I can't get that far I can't even start on working out how to say "early hours of the morning only".
Cheers.
