So, I actually DID upgrade, and had to reinstall 8.1--due to glitchiness caused by old drivers (I kept waiting for updates to come, they didn't, and eventually the 30 second-minute or more long hangs drove me to downgrade)--but I was past the 30 day easy revert period and had to fresh install. Despite having deleted all of the partitions on my hard drive and starting anew (I thought), I am showing various updates from 2014 (prior to my reinstall, which was a few days ago), including the 2 mentioned above--and do not have the option to delete any updates (those or any others) acquired before the reinstall, HA. Halp?!
