If I do a search for Windows 8 Professional x64 in my country, the only version I can find is having the code fqc-05955 and is labeled OEM.

If I perform same search on amazon.com, the only version I can find is having the code fqc-05956 and is labeled System Builder.

There's not much information about licensing of Windows 8 that I could find. According to this article when using System Builder it can be transferred from one computer to another.

What are the differences in licensing between those 2?

Is fqc-05955 transferable from one hardware to another like System Builder is?

Can I install fqc-05955 on a computer I already own that has no prior windows licensing? I am asking this, since many stores that sell fqc-05955 say it can only be bough with a computer.

Thanks for your help!

Both versions you've listed specifically state in their license agreements that you may not transfer the software from one computer to another unless a) it is your computer and b) you remove the software from the previous computer.

Can I transfer the software to another computer or user?

You may transfer the software to another computer that belongs to you. You may also transfer the software (together with the license) to a computer owned by someone else if a) you are the first licensed user of the software and b) the new user agrees to the terms of this agreement. To make that transfer, you must transfer the original media, the certificate of authenticity, the product key and the proof of purchase directly to that other person, without retaining any copies of the software. You may use the backup copy we allow you to make or the media that the software came on to transfer the software. Anytime you transfer the software to a new computer, you must remove the software from the prior computer. You may not transfer the software to share licenses between computers. You may transfer Get Genuine Windows software, Pro Pack or Media Center Pack software only together with the licensed computer.


If you want to install Windows 8 on multiple computers, you must buy multiple licenses. However, the key difference between OEM and System Builder (Personal Use, as pointed out by comments) is that OEM is tied to a specific computer, but System Builder allows you to install Windows on a device with no previous Windows licensing, a detail that you wanted, per your question.

Actually, OEM is also under System Builder. System Builder is split into OEM and Personal Use. Personal Use is more or less the same as the old retail one. –  Bob Oct 31 '12 at 5:17
good point @Bob but either way does the fact that you need multiple licenses for multiple computers change? also, feel free to edit my answer, as I don't quite understand the OEM System Builder yet –  Ethan Lee Oct 31 '12 at 5:22
looks like you have everything else right, just should use the name "Personal Use", since "System Builder" is ambiguous between OEM and PU... –  Bob Oct 31 '12 at 5:23

Based on your Amazon link it seems that fqc-05956 is a version doesn't requires an older version of Windows but would allow you to reinstall freshly. Unlike the Upgrade version of Windows 8 which can only install through an Upgrade.

As for fqc-05955 it seems like that version is just the regular Windows 8 install that requires a previous version of Windows.

Only basing these two answers from what I researched.

? The Amazon link he provided (FQC-05956) is for "Windows 8 Professional System Builder DVD 64-Bit" which "is for pre-installation on a new personal computer or installation on a computer that is not currently running Windows 7, Vista, or XP. This product is not an upgrade..." –  Karan Oct 31 '12 at 5:06
I think you've mixed them up... fqc-05956, or System Builder, doesn't need an older version of Windows edit sorry for the double-post, was typing this comment as @Karan submitted –  Ethan Lee Oct 31 '12 at 5:06
@ethanlee16 You're right. I got them confused because of the model numbers. –  Matthew Wong Oct 31 '12 at 5:10
Actually, fqc-05955 seems to be an OEM version, not an Upgrade as you state. OEM = System Builder, but the licensing is different as ethan mentioned. OEM is tied to the machine you install on, whereas System Builder's separate Personal User License (PUL) allows you to move (i.e. remove from one and install on another) the license between PCs. –  Karan Oct 31 '12 at 5:15
