what does this do allow me to read more CDs?

there is no update.

strange i see a file here says cd firmwire are you sayn it does not exist or its not an update

I am assuming you are talking about the firmwares on xbins, and no, they are not updates, they are just dumps the xbox drives. Same as the retail bios dumps, mcpx dumps, etc.

i see a file named windows, must be a new windows out!
....or its the same version you have now or even a previous version

keep doing that maybe it will make you look feel smart
