I think it was the latest MS rollout today. Everything on my computer,
both C: and D: have been made read only. And I can't seem to fix it.
I've tried to change permissions and it just goes through and seems to
change, however, the next time you access any folder or file, it goes
back to read only. Any ideas on how to get back to normalcy?

AskWoody says "December 2018 Patch Tuesday is under way" and "MS-DEFCON
2: Patch reliability is unclear. Unless you have an immediate, pressing
need to install a specific patch, don't do it."

If you're pretty convinced it _is_ the update (I see three - a .net one,
a system one, and the usual MSRT), have you tried a System Restore?

You cannot simply assume someone is honest just because they are not an MP.
