UAC on Vista

There are several mechanisms by which executables can trigger a request for administrator rights(UAC contorl):

1. If the executable image includes a Vista manifest file that specifies a desire or need for administrator rights (this would be added by the developer who creates the image).
2. If the executable is in Vista’s application compatibility database as a legacy application that Microsoft has identified as requiring administrator rights to run correctly.
3. If the user explicitly requests an elevation using Explorer’s “Run as administrator” menu item in the context menu for executables (also can be set as an advanced shortcut property). Note that this does not run the executable under the Administrator account, but rather under the account of the logged in user, but with the Administrator group enabled in the process security token.
4. If the executable is determined to be a setup or installer program (for example, if the word “setup” or “update” is in the image’s name).
