Re: I suppose a lot of us would like to know...
@mikey - have a look in $Windows.~BT - you will find a nice winbloat file that is waiting for you to upgrade to w10 whether you want to or not.
You mean the one I got rid of as soon as I found it, and knew what it was for? Yes, I removed the cached data for the upgrade, no different to any other downloaded and as-yet-uninstalled update in principle. Sure, the delivery method was underhanded, but an update is all it ever was.
And now it's not. Good computer management, you see. Take steps to secure, remove, patch and protect.
