holy fucking shit this is a bug since october 2017 AND IT JUST INTRODUCED ITSELF IN MY COMPUTER WITH THIS UPDATE IN MARCH 2018 https://answers.microsoft.com/en-us/windows/forum/windows_10-security/important-syslistview32-bug-with-multiple-items/9e6198f7-a38a-4614-bc89-4781a9bde748?tm=1509985739913
MICROSOFT GET YOUR SHIT TOGETHER
how do i rollback this last update
@squirrel Settings > Update & Security > Windows Update > View installed update history > Uninstall updates ?
@InspectorCaracal would do that but i'm 3 hours late for my stream
@squirrel okay, you can give it a try later then if you want; it LOOKS like the fall creator update is listed in that window on my computer, so you should theoretically be able to uninstall it.
I'm starting to wonder if that bug is related to what was causing my mouse cursor to go nuts the other day, though...
