I now have 2 laptops on Windows 10 Home - the one, a newly purchased Dell (Black Friday), and the other, a Lenovo that had Win 8.1 on it. In both cases, I'd done fresh Win 10 ISO installs of the Anniversary Update, so there are no Dell or Lenovo apps on the machines ***
Last night, I decided to check for updates. As soon as I turned on each laptop, I noticed that the data started 'flowing'. As it turned out, the Dell received about 530MB of (background) data, and the Lenovo around 750MB.
Independently checking for updates, all there was for each machine was a minor amount for Windows Defender since the last time I checked a few days prior .. nothing else was available, and everything was up-to-date.
I have both machines set to Defer Upgrades & both are used via wi-fi, so set as metered connections.
Anyone know what might've been downloading all that data in the background ?
Furthermore, I have very few things running on each machine - Chrome, Opera, Firefox, all of which I check for updates manually .. and WPS Office which I've prevented from updating automatically. The one machine has Outlook for GMail.
*** = unless there are apps in the BIOS of each machine downloading things out of my control ?
I can only guess that Microsoft are pushing things out in prep. for this next build coming up in a few months time, without people even knowing it's going on in the background .. as it's not going through the normal Update channel we're all used to.
