What is the difference between Windows 8 Pro and Windows RT?

I know that in the past there have been Home Editions, and Pro Editions, and Starter Editions, but what about this time around? All I keep hearing about is the Pro Version, and the tablet version. Is that it?

Or are there more?

There are four editions of Windows this time around: Windows RT, Windows 8, Windows 8 Pro and Windows 8 Enterprise.

  • Windows RT is designed for ARM CPUs, at the moment tablets only. It will run the new Modern UI apps, but will not run Desktop programs from previous versions of Windows.

  • Windows 8 is the 'standard' version for x86 and x86-64 (32-bit and 64-bit) CPUs, currently used on tablets, laptops and desktops, to replace Home and Home Premium. It will run both Modern UI apps and traditional Desktop programs. Most programs that run on Windows 7 will work here.

  • Windows 8 Pro is the 'premium' edition for x86 and x86-64 (32-bit and 64-bit) CPUs, currently used on tablets, laptops and desktops, to replace Professional and Ultimate. It has a couple extra features on top of Windows 8 (standard).

  • Windows 8 Enterprise is the business/volume licence edition, to replace Enterprise. As a home user, don't worry about this. It is similar to Pro, but missing media center. One notable feature is Windows-To-Go, which lets you boot off a flash drive.

Microsoft has a feature comparison of the different versions. Wikipedia goes into more detail.

While that link is certainly helpful, it would be preferable to summarize the most relevant parts here. – Dennis Oct 26 '12 at 16:35
@Dennis Alright. Bob already did that for me, but I will be sure to do that in my future answers. – Ivan Kay Oct 26 '12 at 16:39
