For about the 20th time, Windows Update pushed KB3035583 as an "important update" even tho' I have it hidden.
That's a Windows 10 upgrade, in case you don't recognize it. Apparently hiding an update doesn't really do much of anything, it just hides it for that version, and MS keeps rereleasing the same patch with different version numbers.
I don't want Windows 10, ever. I have it on one machine and don't like it, and more importantly there are no drivers for my printer.
