Topic: Windows 10 is now being installed automatically without permission
Make sure that you have recommended updates disabled if you use Windows 7, or else you might get a "happy surprise". I have no idea why they'd do it with all the backlash they'll get, but I guess it's worth it if an executive somewhere gets a bonus based on adoption numbers.
I run Windows 7 on my Thinkpad T41, and got hit by this since the CPU in the ThinkPad won't support a version of Windows higher than 7, it tried to update and ends up blue screening whenever it starts. I still have to reinstall Windows 7 on it.
