Microsoft officially announced the Windows 8 arm version named Windows RT

Comparison of functions in three versions of Windows 8

Microsoft (Weibo) announced today that four versions of Windows 8 will be released for major enterprises in household use, enterprise, ARM architecture, and bulk procurement.

For most desktop and notebook users, only Windows 8 and Windows 8 Pro versions are available. The latter includes functions such as encrypted file system, virtualization, and domain name management.

Windows RT is designed for the ARM architecture and cannot be purchased separately. It can only be pre-installed on PCs and tablets using the ARM architecture processor. Windows RT is not compatible with x86 software, but will come with Microsoft Word, Excel, PowerPoint and OneNote designed for touch screens.

The last one is Windows 8 Enterprise, designed for large enterprise customers. In addition to Windows 8 Pro, some functions designed for large-scale management of large enterprises will also be provided.

In the previous versions of Windows 7, there were 6 versions, and only domestic users had 3 options. After the version was reduced, Windows 8 would be easier for users to differentiate. However, Microsoft did not disclose the price and time to market of each version in its official blog.
