What is the difference between RTM and RST? I only know there will be PC, Tablet, Mobile etc editions? Also I know there will be a Windows 8 Pro release too.

@akula - Don't ask question you didn't research before hand. –  Ramhound Oct 22 '12 at 16:35

RTM means "Released To Manufacturing" and was already available over the Internet (MSDN) before the official release date and so many developers already use this final windows.

Before the RTM there was also the "Release Preview" Version, that is more like the Demo Version and was for free, but has an expiration date.

Otherwise the Windows 8 family is called Editions. There are 4 main products:

  • Windows RT (for ARM Processors - mainly for Tablets)

  • Windows 8 (Standard Windows 8)

  • Windows 8 Pro (replacing the Windows 7 Ultimate, with additional features)

  • Windows 8 Enterprise (some additional features, but no Media Center)

See the Wikipedia Post of the Windows 8 Editions.

RST Intel® Rapid Storage Technology has nothing to do with Windows, but maybe you refer to the Storage Spaces feature in the Windows (non RT) versions.

Thanks. What are RTM and RST like? –  akula Oct 22 '12 at 13:34
@akula - Your question is not clear. RTM is release to manufacturing RST is Rapid Storage Technology its not a version of Windows. Do your own research. –  Ramhound Oct 22 '12 at 13:42

Windows 8 RTM stands for Release to manufacturing. This is the final version that goes out to manufacturers and will eventually be released for sale - it comes in different editions such as standard/pro/enterprise.

The difference being, standard (or just Windows 8) is the main stream version, Pro allows for joining domain and enterprise is pretty much the same as pro with some additional features that are good for businesses.

RST stands for Rapid Storage Technology that is an Intel technology and not specifically to do with Windows.

Windows RT is the version of Windows that is designed just for ARM based devices such as tablets.

Wikipedia has a good table to show you the difference in versions
