I use a mix of Windows 7 and *nix OSes both at home and work.<p>At work we do have some Win10 machines, and they are ALWAYS doing something completely off the wall bizarre and unexpected, also doing any sort of maintenance on them is a pain, the tablet-style interface shoehorned into some places just doesn't work well.<p>I know Win7 support is over, but we don't intend to leave it for Win10, we might leave it for Reactos or something else, but not Win10.<p>Some examples of Win10 issues:<p>sending tons of data to MS without permission.<p>Not allowing us to install with local account unless we disable network on the EFI.<p>Despite we trying everything to disable updates, the thing updates itself, reset several configurations, and reboot the machine.<p>One of the times it did that, it broke some ancient but mandatory software on our business (it was a PDF driver that was mandatory to be used by our bank that would issue the invoice for our clients, so when this happened we were forced to install all banking software on a Win7 machien so we could get paid...).<p>Showing ads out of the blue on Start menu and on the login screen.<p>Installed games without permission (not Microsoft ones, I mean stuff that is popular on mobile, from king.com and whatnot).<p>The list goes and goes on.
