I build a small volume of machines, for friends and family and decided that it would be in my interest to sign up to the Microsoft OEM Partner Scheme. In there it offers all the licencing information.
Having read all this thread, and also the OEM System builder site at Microsoft here is what I determine to be.
1.If you install an OEM or Retail Version of Windows Vista (all types) on a Personal Computer, it MUST be activated. I may be wrong, but as I understand it absolutly ALL versions of Vista including Volume Licence (Generally known as "Corporate" versions) will have to be activated also, if the machine is not connected to the internet, then it will require telephone activation.
2. If you install an OEM version of Windows Vista on a machine and the motherboard then goes faulty, you MUST replace it with an identical model. If your faulty board is a MSI 875P Motherboard then the replacement must be the same identical board,
or a board that MSI would consider its direct replacement. If you use any other board better or worse according to Microsoft:
An upgrade of the motherboard is considered to result in a "new personal computer" to which Microsoft OEM operating system software cannot be transferred from another computer. If the motherboard is upgraded or replaced, for reasons other than a defect, then a new computer has been created and the license of new operating system software is required.
If the motherboard is replaced because it is defective, you do NOT need to acquire a new operating system license for the PC. The replacement motherboard must be the same make/model or the same manufacturer’s replacement/equivalent, as defined by that manufacturer’s warranty.
The reason for this is two fold, one this is because the system builder is required to support their machines, if the motherboard is changed by an end user (because thats how we are looking at it) then it is considered to be no longer the system builders machine, as it was replaced with another board, and hence the system builder would not really support a machine that they did not build. In our case we build our machines, but the rule has been put in place for the hundreds of small builders that build for other people. The second part, is that the machine is considered no longer the original machine when the motherboard containing the processor and other major system parts, has been replaced.
3. If the distributor sells you an OEM copy of the software it must be inside the Break the seal box, in this case, a distributor can sell the sealed box to a system builder or end user for installation on their machine
Without hardware. Once the box has been opened any further distribution of the software MUST be with a system. If it is installed on a system to be sold to an end user it must be installed with the OEM Preinstallation kit available to System Builders.
An end user (like us) who purchases the software in a Break-the-seal box, and installs it on their own machine is considered by Microsoft as a System Builder.
Hope this helps, someone!
