Change the default scripting engine from Wscript to Cscript. (The Xcacls.vbs script works best in Cscript.) To do this, type the following at a command prompt, and then press ENTER: cscript.exe /h:cscript Note Changing the default scripting engine to Cscript only affects how scripts write to the screen.

Here is the easiest way to open elevated command prompt: Click on the "Start" button In the "Start Search" box type the name of the program you want to run as administrator. For example type CMD or CMD.EXE. Do NOT hit ENTER. Instead hit CTRL+SHIFT+ENTER. It seems that this key combo triggers user account elevation and is identical to the RUNAS command or the GUI "Run as administrator" option. You will be prompted by the UAC warning window. Click on CTRL+C or click on the "Continue" button. Note that the CMD window has an "Administrator:" appended to the window title. You can now perform any administrative tasks you want.
