Windows 8 security user account permissions

I'm using Windows 8 Pro.
When I try to save an attachment from Outlook 2010 into a specific Program Files folder I get the following message:

"C:\Program Files (x86)... You don't have permission to save in this
location. Contact the administrator to obtain permission.

Would you like to save in the folder instead?"

I upgraded my Win7 pc to Win8. The first time I used Windows 8 I signed in via my email address (4 or 5?). But then I added it to our domain and signed in with my domain account (3).

Now when I look at the "Control Panel > User Accounts > User Accounts" I see the following things:

(1) HomeGroupUser$ |  | HomeUsers
(2) UpdateusUser |  | HomeUsers
(3)  |  | HomeUsers; Administrators
(4)  | MicrosoftAccount | HomeUsers; Administrators
(5)  | MicrosoftAccount | Administrators

the "my domain user (globe icon)" (3) is the account that I use currently and It has been added to the "HomeUsers; Administrators" groups, but still that message tells me i'm not an administrator.

I also linked my MicrosoftAccount (4 or 5?) with my current domain user account (3)

Any suggestions on how to make myself an administrator on the pc so that I don't have these annoying UAC messages and that I can write in my own program files (and other folders)?
I thought I was an administrator now, because my domain account (3) is in the groups "HomeUsers; Administrators" but that doesn't seem to be 100% ok.

Thanks in advance (sorry if this explanation is a bit messy).

Answer

You are still an administrator - The exact same thing happens in Windows Vista and Windows 7... Unless you launch Outlook as an administrator, you will not have the ability to save to or write to protected paths.
