Why Am I Not The Admin Of My Own PC?

Due to complications, I once again had to reinstall Windows. No big deal, at this point I have EVERYTHING backed up, it's a 30 minute inconvenience and everything that's wrong is magically better...

Anyway, I'm just trying to simply move files like "Downloads" to my desktop for easy access.
And some other things are asking me for permission as well.

It shows this:

I click OK or continue,whatever. It starts to transfer it and then I get this, and "Try Again" does the same thing over and over. Not working.

I hit properties, and went in, set it to admin control or something... I don't know I'm sure this is an easy answer, who's got it?

I did what one online answer said and it didn't work
