Reset a notebook, now I can't access Windows Security?

[MarkH2O]

Hello.

Yesterday I had to reset my HP notebook.  (Some font stuff was screwed up, and only a reset could fix it - it was virus-free.)

I did a reset (keeping my apps and files), and everything came back, exactly as I'd hoped it to.  But now I can't access any of my Windows Security.  A blank screen comes up (black on my computer, assume it's because of the dark theme), and just sits there looking at me.  The best that I have ever gotten is the following note.  It shows up at the top of the screen in a white box:

• Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available.  Contact IT helpdesk for more information.

I am my IT guy!  It's a personal notebook, and before the reset, I had no problem accessing Windows Security.  I could use it right up to the second that I hit reset.  The only unusual thing is that during the Reset Windows told me that I had to turn off my Core memory in order to properly reset it.  Never heard of that before.  Anyway, I did, but even after that had been reset, I could use my computer like normal.  But now, after a reset?   No access.  I was initially trying to access it to restore my Core memory settings.   That's when I discovered the entirety of the Windows Security issue.  Obviously, this is very serious.

I am the Administrator account.

Thank you so much!
