That should read: [HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor] "AutoRun"="C: && cd \" Note the single backslash. Otherwise you get an error (surprise...). Thanks for this though! Very nice! Cheers! I know this is a newb question, but after navigating to HKEY_LOCAL_MACHINE\Software\Microsoft\CommandProcessor\AutoRun , I assume I then right click on AutoRun, choose modify, then type "AutoRun"="C: && cd \" into the value data box. Is that correct? (And if it is, do I use the quotation marks, or not?) TIA
