I haven't run Microsoft Updates on my Windows 7 installation since July 2015 because Microsoft started down this road of forcing Windows 10 down users' throats.
The reason for installing updates is to prevent bad things happening to your system, but when the updates themselves pose a bigger risk than being infected from (other) sites on the Internet, stopping updates seems the better choice.
I will eventually update my laptop from Windows 7 to Windows 10, but it will be at a time of my choosing, not dictated by the bullies at Microsoft.
Updates can go wrong, they can stall, your system could end up not bootable, or you could lose the ability to run important software that is incompatible with Windows 10. Microsoft wants to force Windows 10 on everyone, which makes them responsible for any bad thing that happens during upgrading, but they would of course never actually take responsibility for those bad things happening.
I've upgraded another system from Windows 7 to Windows 10 and it took some googling and some non-intuitive operations to get the upgrade process to get past a couple of stalled states. So I'm not just speaking of problems I read on teh intarwebs.
How many people, who get their pc's fubared during a forced Windows 10 upgrade, will simply decide to give Microsoft the finger and go buy an Apple computer that "just works" ?
