Difference between two Vistas on Newegg

Hi

Main differences from memory are that these are OEM over Retail so have NO support from Microsoft, as system builder versions the support comes from the system builder, if thats you then you are your own support, these are same versions that the likes od DELL, HP etc use. Also they are as OEM tied to the PC they where first installed and activated on so unlike Retail versions you cannot easily move these versions to a different PC.

DSP and OEI are a bit of a naming system from OEM to narrow down the various versions per system builder type.

DSP (Delivery Service Partner) is a non bios locked version for smaller system builders that dont get large discounts and this version is also tied to the original PC its installed on so this is also not transferable, lives and dies with the PC. Can only do a full install with these version as they dont upgrade from XP etc

OEI ( Original Equipement Installation) are the versions that do come with the likes of Dells etc

With these versions you have a sticking point, if your a person that upgrades hardware alot, after 5 changes of non-peripheral components the machine is deemed as NEW so a new licence is needed!!


Personally depending on your PC knowledge and if you are going to be changing hardware alot then I would go with Retail if your knowledgable and are not going to be changing loads of hardware in the PC then OEM is fine, I run 1 laptop of mine on an OEM version.
