Licensing Issues

 

For the most up-to-date licensing information, refer to the microsoft web site.

Retail

2000 Pro, XP Home, XP Pro, Vista Home Basic, Vista Home Premium, Vista Business, Vista Ultimate.
you may transfer the software to another computer (nothing mentioned as to how many times, though a situation like this calls for a rebuild and if enough HW changed, it may trigger a need for an activation call to microsoft with an explanation as to what you were doing). you may transfer the software one-time to another person. You are also supposed to transfer the Proof of License label.

you could not use an OEM XP installation CD to downgrade a copy of Vista, because the OEM license was restricted to one machine (both OEMs, both legally purchased). You must purchase a legal copy of an XP Pro Retail cd.

The Retail version is the one you use now as of Oct 2011 for users desiring to build a system.

Upgrade

2000 Pro, XP Home, XP Pro, Vista Home Basic, Vista Home Premium, Vista Business, Vista Ultimate.
license for XP Home upgrade says license limited to 1 CPU. I can't remember, but I thought it said 1 workstation too. maybe it said 1 CPU, which makes sense.

OEM

2000 Pro, XP Home, XP Pro, Vista Home Basic, Vista Home Premium, Vista Business, Vista Ultimate.
the package basically says "to be distributed only with a new computer". and it is meant to stay with that computer. That's why you're not paying the big bucks for the retail version of Windows.

you could not use an OEM XP installation CD to downgrade a copy of Vista, because the OEM license was restricted to one machine (both OEMs, both legally purchased). You must purchase a legal copy of an XP Pro Retail cd.

You can buy the OEM with either a new system, or buy with a piece of hardware. The OEM version with the computer it is installed on. [this license has changed! NO LONGER TRUE! now only for system builders, and this does not mean users who are building a PC. users who are building a PC must still buy the Full Retail version of Windows. I guess microsoft decided they weren't making enough money.]
