Windows RT is a stripped down version of Windows 8 which has been designed to run on ARM processors. While it features the same interface as Windows 8 including the classic desktop it is unable to run legacy (regular) Windows apps. Instead Windows RT users are restricted to downloading apps from the Windows Store.Meanwhile developers have been hard at work attempting to jailbreak Windows RT and a hacker named Clrokr has found a way to bypass the security check on Windows RT, which will allow running apps which has not been signed by Microsoft.
Clrokr has also found that Windows RT is the same as Windows 8
They are the same thing and MSFT enforces Code Integrity to artificially separate these platforms... You can even enforce Code Integrity on Windows 8 to see what Windows RT feels like! The decision to ban traditional desktop applications was not a technical one, but a bad marketing decision.So it seems that the only difference between Windows 8 and Windows RT is the minimum level security check, which restricts running apps which have not been signed by Microsoft. By bypassing this check unsigned apps are allowed to run on Windows RT machines, however the current jailbreak doesn’t hold after you restart and needs to be repeated. In any case this is great news for the jailbreak community.
This makes some sense, especially in the fact that Windows RT takes up so much of disk space. It looks like Microsoft has chosen to modify the full Windows to support ARM rather than build an ARM based operating system like Android or iOS from ground up.
It is quite frustrating to know that you have a full operating system which has been locked down by Microsoft, probably with the intention of producing better battery life and performance on ARM processors.
