Sorry if this was covered, but is there a specific update number (KB.......) that is the thing to have right now? Can we download it direct from the Microsoft sites?
At the moment, I'm having trouble installing a couple of the .NET Framework updates (error 80070BC9). I ran the generic update installer FixIt recommended by the Windows routine, but that didn't seem to help. Ran Malware Bytes scan and didn't find anything especially strange (just PowerISO, but I installed that and I don't think it's evil?). I'd really like to solve this without invoking Microsoft Security Essentials or Windows Authentication, as I'm on a black Windows and have those both turned off.
Everything else labeled Important has installed fine (except I haven't bothered upgrading Internet Explorer from 10 to 11 yet, as it's a secondary browser for me and I like to stagger things particularly while in China).
Thanks for the update. Uninstalled Adobe -- the constant updates were a pain anyhow. Sumatra looks alright enough, at least at a glance.
