Windows 8 , the much anticipated OS is finally out !
You can install it on a x86-based 32-bit or a 64-bit machine.
Activation is not required, but it’s far from a finalized version of the OS, so if you do install it, expect bugs and glitches.
In any case, you should definitely check out Microsoft’s Windows 8 guide to get an idea of what you can expect from the next version of Windows.
