VecchioScarpone, Regarding KB3068708, I can merely suggest that it isn't doing anything helpful to you. The description is vague indeed, which is not a good sign. I recall hearing about it being more closely involved in the "gwx" business than the description suggests it is, although I might be remembering something said about one of the other "nasty" updates I listed. The key thing to note is that this update definitely doesn't improve security, patch a bug or anyhting like that, so even if it isn't as bas as many think it sounds, it certainly isn't very useful. To install, or not install, that is the question, and it is YOUR choice, but speaking for myself, I haven't installed it and don't plan to.
TCSNinc, could you take a loom at the ~BT folder in more detail, say precisely what the names of the files in it and the folders in it are? it might not be related to windows 10, it might be something else entirely. If you post the names of the files and folders you see upon first opening it (you needn't bother trying to list every file and folder in it at every sub-level for I expect there will be hundreds) it might help people here to work out if it is the ~BT folder related to windows 10, or if it is for something else.
You should be able to install security updates, without installing windows 10, right up until the end of the extended support lifetime for windows 8.1. As long as you are careful to check what updates are being offered to you, and make sure that anything forcing you onto windows 10 (it happened with KB2973544 with the windows 8 to 8.1 upgrade, so we can't be absoutely sure* that ms won't try something with the 8.1 to 10 "upgrade") doesn't get installed, avoiding KB3035583 and it's unpleasant friends is a good first step.
Also TCSNinc, please search(from within windows file explorer, not from the other searching utilities on the system) your C:\ drive (assuming your windows files, system files, program files... are on C:\) for the three letter phrase gwx see if any results are returned, make sure to have "hidden files and folders" set to show, but you should NOT need to set "protected operating system files" to be shown. Please post and say whether anythong containing the three letters "gwx" can be found by searching your C:\ drive.
*They aren't doing forced upgrades from 8.1 to 10, yet, but there is a small chance that they MIGHT someday, no-one is FULLY sure.
