Senior executive Mike Anguilo confirmed that Asus, Dell, Lenovo and Samsung will develop devices running the software, complete with both physical keyboard and touchpad solutions.
"Our engineering collaboration on these Windows RT PCs has been strong, collaborating with the PC manufacturers, silicon partners and operators to focus on hardware, software and services integration," he said.
"Product designs were informed and revised by our collective efforts through development and testing.
"As a result, all of these Windows RT PCs will have consistent fast and fluid touch interactions, long battery life, connected standby, and are beautiful, thin, and light designs."
Windows RT is an iteration of Microsoft's upcoming Windows 8 OS designed specifically for devices powered by ARM processors, such as tablet computers.
Microsoft previously announced plans to enter the tablet hardware market with the release of its Windows 8-powered Surface tablet, a move which was deemed risky as it could alienate its manufacturing partners.
Surface will be released alongside Windows 8 in October.
