Windows 10: how to give administrator rights without admin

So with my pc I guess i didnt log in with the guest account when i first got it or something because my guest account has admin but my main account doesnt. I have looked up certain commands like i know how to get into recovery mode and use the console from there and i did the net user command to add localgroup administrator to my main but whenever i get this kinda like request for permissions by a trusted app battle.net probably trying to update a game it says i need to contiune with admin password and username which if there was a contiune i would hit it but there isnt. It says only a no b

admin rights keep disappearing!?!!

Hi guys,

I am actually having a problem at work that our IT department hasn't been able to figure out. I am supposed to be a member of the admin group. We are on a domain. The problem is that everytime I reboot the computer I loose my admin rights(no longer in the administrator group) and just become a normal user again. I have tried googling this and didn't get to many results.
I believe IT is just giving me local admin rights, not admin rights for the whole domain.

Any suggestions?

EDIT: It is on Windows XP Pro.

 

Windows 10 Admin rights?

I am becoming increasingly frustrated with windows 10, for some unexplained reason the photos app stopped working, the suggestion is to uninstall and reinstall this app, however the system reports that I do not have admin rights to perform this operation!

I wonder who does, I log into windows as an administrator and could do anything, this is a new problem since upgrading to windows 10 on my single user personal laptop.

I did find a community post showing the following instructions:

I request you to follow the below steps and disable in built admin account on the computer.

• Open Command Prompt in Admin mode.
• Copy and paste the below command and press Enter.

net user administrator /active:no

3.Close the elevated command prompt.

4.The built-in Administrator will now be available to select to sign into.

However all I get for my trouble is access denied error 5

So where do we go from here?

I am 66 already and cannot wait forever to sort this please help
