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.
The script below will check if it is running with elevated (Admin) permissions, if not the script will popup a UAC prompt and relaunch itself. The script saves the current drive mappings and then re-maps them once the session has been elevated.

Source: The script above is losely based on batchgotadmin plus some ideas from this forum thread.
.ShellExecute - Run a script/application in the Windows Shell (elevated)
