Make a USB Stick act like a CD
After reading the comments below, it seems that Windows 7 only supports the label and icon entries. I followed the link they commented and read that only CD's are allowed to use the autorin.inf entries.
Are there any ways on how to load the usb as a cd drive? I researched and only saw people loading a usb as a hard drive with the use of a custom inf file.
