Notably missing from this list is "Windows 8", which stands-in for the Standard/Home version of the desktop OS (probably modifying the same media could surface it). There is no news about Windows RT, the ARM version for Tablet devices. Similarly, the Windows Server 2012 Essentials edition has also not made an appearance in the leaks at the time of writing.
Reports are coming in that a serial key is required for installing Windows 8 - both the Volume License and the normal Retail editions. As far as Microsoft's activation servers are concerned though, this OS does not exist and will not be released until another week passes. In any case, the only keys available for entering at present, are the trial keys that are present on the Windows 8 DVD itself (see the file "product.ini" in the "sources" folder).
If you have already reached the Product-Key entry screen, you could look-up a key to install Windows 8 RTM online, from this text file. Volume License copies must be activated by a KMS server, retail copies with a key from a store purchase. Reports are filtering in that this version has retained "1000x re-arm before activation", but we could not test it yet.
