Microsoft made its deadline for the completion of the Windows 8 RTM (Release to Manufacturing) build as they previously scheduled. However, that wasn't the only Windows-based OS that got the official sign off today.
TheNextWeb.com reports that Windows RT, Microsoft's brand name for the version of Windows 8 made to run on processors based on ARM, has also reached the RTM build stage. In addition, the story claims that Microsoft has already sent out the RTM build to hardware makers that are building Windows RT devices.
Qualcomm, NVIDIA, and Texas Instruments will be the companies that will make the ARM-based processors to run on Windows RT-based hardware(Windows 8 runs on x86 processors made by Intel and AMD). Microsoft has already announced that it will not sell a stand alone version of Windows RT; it will only be available for consumers when they buy a new hardware product with Windows RT already installed.
Microsoft will launch the Windows RT version of its Surface tablet PC on October 26th, the same day as the official consumer launch of Windows 8 and Asus has also confirmed it will launch a Windows RT-based device. Another version of the Surface hardware, running on Windows 8 Pro on an Intel chip, won't launch until at least 90 days later.
