Kb3024777

Hello, I am new to the post but I have been reading the posts regarding faulty KB3004394  earlier this week.  Unfortunately I installed all of them yesterday just before MS removed it from their server.  A few minutes ago I received a new "important" update KB3024777 ready to download but when I tried to find info on this download, no information comes up on it at Microsoft.  Has anyone else received this to download today?  Also I am unable to run command sfc/verifyonly as it says I must be administrator. How do I go about doing this?

I have not uninstalled KB3004394 yet as Microsoft forum recommends.  Should I uninstall the faulty update?  Is this new update KB3024777 a fix for the faulty one? I'm so disgusted with MS...I'm not a computer savvy person and all this is very stressful for me.
