What are the rules for buying OEM software?
Microsoft OEM software is sold for installation on a new PC by a system builder. A system builder is anyone who builds and sells new, complete or bare-bones PCs or servers. When you break the seal on the product you are accepting the OEM System Builder Licence terms - the key elements are that you should install the software onto a new machine and that software is tied to that machine and is non-transferrable.
What are the rules for installing and distributing OEM software?
You must preinstall the software on the PC using the OEM pre-installation kit (OPK). The OEM license on one PC cannot be transferred to another PC. Check the Microsoft OEM System Builder License link below for the complete rules.
