With the system build if you decide do upgrade a part of your pc do you need to buy a new copy? or mother board crashes you would. Also if you reformat you're pc can you reinstall windows with the system builder?
So the second one i could install on multiple computers?
Not simultaneously AFAIK, but sequentially. Which means you wouldn't need to buy a new Windows when you replace your computer. And even if you wanted a newer version of Windows, you could just buy an upgrade to apply over your old Windows 7, and upgrades are usually a lot cheaper.
no, you can't do that, still only 1 active computer.
But you can use the Retail license on your current computer; then some time in the future on your next computer (may require calling microsoft number)
The oem one is supposed to be 1 and only 1 computer, period. If you build a new computer, it will say this key is no good anymore, call microsoft, and they are supposed to tell you to buy another key.
However, it is reported that depending on which microsoft rep you get, even though you don't deserve it, and you just have an OEM license, sometimes they give you a new key when you call; even though they should be saying you need to buy a new license
OEM versions of Windows 7 are identical to Full License Retail versions except for the following:
- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel
- OEM licenses are tied to the very first computer you install and activate it on
- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard
- OEM versions cannot be used to directly upgrade from an older Windows operating system
Here's the word for us "hobbyists":
There is a growing market for "do-it-yourself" home PC hobbyists who assemble PCs from components for their own use. Microsoft retail software licenses are the appropriate licenses for the do-it-yourself market. OEM System Builder software is not intended for this use, unless the PC that is assembled is being resold to another party.
