Windows 10 = HAL
Windows has been trying to upgrade me to 1709 this month. After so many Remind Me Later clicks it finally tried to force it on me. The only way to stop it was to cut internet access. It still nags me every time I boot up but it's dead in the water without internet. I suspect there's a built in revolt mechanism that in time will either try to force an internet connection or completely shut down all together. Once I decide it needs internet, the upgrade will be inevitable.
Either way, I now use a Windows 7 machine for internet.
... good thing my name isn't Dave!
