Re: "Just don't use Windows 10 on-line."
No problem AC just you go and ask MS to respect your privacy. Or maybe take them to court? Really you and anyone for whom you provide help have only a few workable choices:
1) Use windows and bend over for whatever MS decide to do.
2) Use an alternative arrangement and accept its more trouble for certain things.
3) ? Underpants & profit ?
If you actually have a better, more workable, suggestion than mine (Linux host, windows in restricted VM) please let all us commentards know.
