Hi! I am a Windows 8 user since Developer Preview and I'm considering Windows 8 a niche product, especially with the 8.1 update that may bring back the start menu and may have many tweaks. I want to reinstall Windows 8 on my UEFI-enabled laptop, and I also want to activate it, because I can't stand the ' Activate Windows ' watermark and not being able to personalise the Start Screen. My questions are: Do I have all I need to activate W8 via KMS in this thread? - can't include link - I meant the Windows 8 KMS Activation stricky thread. Do all the Professional (Pro) versions of Windows 8 are volume license type? Should I install Windows 8 Enterprise or Professional? I know about the Windows to Go feature that it's in the Enterprise one, but... I think I won't be able to upgrade to Windows 8.1 or 9 or something.. What do you use, and why? PS: I'm now running a 6 old month Windows 8 Enterprise installation, unactivated Thanks everyone !
