UAC and one program used very regulary

Hello Gill and Welcome to the Microsoft Answers Community.

The main reason, why you are getting the UAC prompt for that program is because the program must pass the UAC elevation. In order, for that specific program to pass the UAC elevation, a UAC prompt must appear, since the new security technology in Windows Vista™ and Windows® 7 works this way.

User Account Control (UAC) was designed for preventing malware executions in PCs, but also to prevent users from doing things wrong (e.g. turn off security features which they should not).

The UAC security feature doesn’t have a “list” and a “black-list”, were trusted programs can be added. The main reason why, the program runs as administrator is because, that program might require doing so, so it can have full access to different directories, or Windows Registry.

The UAC feature is built-in deep inside the Windows Kernel and the Windows Account System.   

So the question is: If you do not like the UAC prompts then turn off UAC, or modify the Windows Local Policy Settings.

To elevate without prompt follow the steps below.

Steps to follow:

    1. Click  Start and in the instance search type "Local Security Policy" and 
         as it appears in the search result, press Enter to run it, note: UAC will prompt.
         So pass the UAC prompt correctly.  
         (Note: You can also press  + R and when the Run dialog appears type: "secpol.msc" and press Enter).
    2. Now expand the Local Policies tree, and click on the Security Options.
    3. On the right-side a list of security settings will appear, search for "User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode".
    4. Right-click on it and choose Properties a dialog will appear.
    5. In the middle of the dialog, you'll see a comboBox with the default value = "Prompt for consent for non-Windows binaries".
    6. Click on that comboBox and choose "Elevate without prompting", click Apply and OK
         (Note: This does NOT require a PC reboot).
    7. Double click on the program to verify if it works, but, trust me this will work.
