In Windows Vista and above, you can run a script with elevated permissions by right clicking and choosing "Run As Administrator" but it’s also possible to invoke the UAC dialogue by calling the VBScript .ShellExecute function.
When a script is run with elevated permissions several aspects of the user environment may change: The current directory, the current TEMP folder and any mapped drives will be disconnected.
