Message Boxes on Windows 7 with UAC Enabled

5 posts in this topic

At times I need to deploy an AutoIT message box or a GUI display  that will appear on the user’s screen, usually containing a message of some sort, installation status, etc. This is problematic for me in Windows 7, as User Account Control (UAC) prevents the message from being displayed without a truly ugly Windows message, prompting the user to authorize the display, and then disrupting the video in general.

My research has found that, unless the script is running under the context of a local user account, that this behavior cannot be changed if UAC is enabled (which it is).

The client used for software distribution (Fiberlink's MaaS 360) runs under the context of the local SYSTEM account. How can these types of messages seamlessly display on Windows 7 systems with UAC enabled?

What else could be causing it? The same script runs fine on an XP box. On Win7, the message displayed is "a program running on this computer is trying to display a message".

If you #requireadmin, and don't initiate with elevated permissions, the UAC comes into play (at script startup).

You can use scheduled tasks, or [ps|pa]exec, to initiate with proper rights.

Edit: Just saw your post, your script is probably running on session 0, which is behind the desktop...again, my above suggestions will work, with the proper params.

The problem happens because you're running under the System account and trying to display a message to the user level account. There isn't any way around this because it's a security issue.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
