For some reason the symbols I try too write gets removed when I post. write: "net localgroup administrators
then write your username like this (username), but replace () with the "crocodile mouths" next to the z on you keyboard.
finally you finish off with /add"

Error in my last post. "net localgroup administrators <Your username> /add"

No problem.

You could add yourself as an admin again. Press Start+X and choose the administrator console again, Then you write: "net localgroup administrators <Your username> /add"

This should fix your problem once and for all.

Have a nice day.

It will work if you restart the pc, but you will maybe have to deactivate the local administrator from activating itself later.

I have solved the problem. It is not a problem with Opera, but windows 10. Turns out windows can turn on the local administrator without permission during a update. You have to deactivate it to get normal admin rights back. Look here for help. http://www.tenforums.com/tutorials/2969-administrator-account-enable-disable-windows-10-a.html My Opera works fine now.

Some extra info. I am the only one who uses this computer. I use ii both home and school. I have not installed anything new before this happened and I tried running it as administrator. The only difference is I have no Opera programs running in the background.

I have the same problem. I have the Norwegian versjon. I get the same error message in my own language. I am my pc's system admin, and i get the no acsess still. It was working fine yesterday. There is no maleware, or anything like that. I have win 10.
