Windows Vista's UAC feature is designed to minimize security risks by running most applications under a standard user token, lessening the risk that an attacker could gain admin rights to the machine.  UAC allows executables to specify what privelege level they require -- if an app doesn't provide a specification, it will be run in the context of a standard user, but UAC will provide some virtualization features to make it appear as though certain admin tasks succeeded.

Ian Griffiths presents another screencast that covers the default virtualization behavior, and then shows how to write a UAC manifest to specify a desired privelege level, for both native win32 apps and managed .NET apps.

Be sure to also check out the UAC team's blog, as well as How To: Use Vista's UAC Feature To Avoid Always Requiring Admin Rights.

Here's an example of a manifest:

<?xml version="1.0" encoding="utf-8"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel level="asInvoker" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</assembly>

Note that you don't need to edit the project file to add a Win32 resource to a C# project. You can do this through the UI. Go to the Application tab in Project Properties, then under Resources, click the Resource File radio button. Enter the path to your .res file in the edit box or use the browse button to locate it.

If you still want your application to have an icon, you need to include it in your .rc file. You'll want something like:

1 ICON DISCARDABLE "myicon.ico"
The problem here is that if you have existing resoures (version info) it gets overwritten, so the resulting executable doesn't have the version info - at least that's what's happening to my app.

I love Windows Vista! It actually took me a while to get use to this program. Hopefully Microsoft will continue whith these great products. There is somethings I dont like about vista like the Administrator function. Most families dont need an adminstration process.

I am horrible at anything to do with computers. I sell printed circuit boards and I am no expert like many of you in programming. This information has been very helpfull to me and I am starting to learn the basics. I am going to get the windows 7 next week and I cant wait. Thanks for the great post.

I am so excited about windows 7. Hopefully there will be no administration function on this model.  Like others have said there is no need for these functions for family computers in my opinion.  I have a wedding DVD store and I am interested in these functions for my business only. There should be some sort of option. I think Microsoft is doing a great job with these new systems.

I work for several banks and I am a definetly a hard money lenders. Im glad you guys are here to take care of the technical stuff that I am not qualified to handle. I apprecite you deeply and you make my job much easier. I just wanted to say thanks and show my appreciation.

 

I have a cricket bats website and I want to setup different priveleges for different users. I want to do this for different purposes especially editing and design. This post has been very helpfull and hopefully I will get the hang of this. Thanks

I work for a consumer complaint company and I really need to get a good webdesigner or programmer because I really cant keep up with everything. This is so complicated and I have a hard time following this.  I will keep working hard to get everything working correctly.
