Thanks for the inputs guys. I'll do it on my day-off and come back with a report. Appreciate all your help.

I don't have the cd for Win10 (upgraded to it before the free offer expired). How can I obtain the recovery tool from Kyhi?

I upgraded to Win10 before the free offer expired and I don't have a cd for that. Who is Kyhi and how can I have the recovery tool?

Ok now I know what you meant, I got confused....I was referring to the screenshot you posted. This is what came out::

C:\Users\AD5MD>net localgroup administrators
Alias name ...

That's what puzzles me, I am logged-in as (my username) but still won't give me admin privileges. I checked under control panel/users amd it shows me as a local account. Tried to right click on CMD...

Run the command and it showed exactly what you have posted.

I don't think it is the software that I'm trying to install. It happens on any application, can't even change the time on the pc

I need to install a software but when I click the file the UAC comes out and asks the usual questions. What I find weird is it does not give me the option to click YES. Only the NO button shows up....
