Listen, and understand!
Windows 10 is out there! It can't be bargained with. It can't be reasoned with. It doesn't feel pity, or remorse, or fear. And it absolutely will not stop, ever, until you are running it.
My home machines are all running W7 pro and joined to a samba4 domain... at first I thought I'd be safe because domain-joined machines weren't installing the GWX bollocks and I've only been (manually) installing the security updates. But lo and behold I spy the "install W10" option ticked.
Starting to feel a bit like Kind Cnut demonstrating the futility of trying to hold back the tide, although it's Nadella and co who are happily acting like cnuts. Any fragments of trust I had for MS are now gone completely and W7 will be the last MS OS I use at home.
