Help: My only account isn't an 'administrator'

I recently downloaded Windows 10. For some reason, my account on the computer --which is the only account on the computer-- is a 'standard account'. Because of this, I can't download or make some important changes that I need to make. I admit that I'm not computer savvy, but I've tried a few things. I've tried activating the 'hidden' Windows 10 administrator password but I can't because you have to run the cmd as an administrator to do this [when I try it doesn't give me the option to click yes]. I also tried adding family members to my account in order to make those accounts administrators. I created new email addresses, send the invitation, and accepted the invitations, but every time I log on to my Microsoft account, it still states that they invitations are pending.

At this point, I really don't know what to do. Does any one have suggestions or clarification questions?

Ok jwelle2, read the information on this tutorial It will give you lots of choices on how you can get your admin rights back. If all else fails, Option #4 would be a good choice.

Options 1-3 haven't worked.

I'll try option 4 and update this page for other people that are having this problem
