OEM version will not allow you to upgrade the motherboard whereas the Full Retail will.
Wrong...
OEM means there is no support...you cannot call in to have them explain how to plug in a USB cable...
OEM versions can be installed ad-infinitum on unique hardware footprints...BUT NOT CONCURRENTLY
Unless you need 'Microsoft Support'...its idiotic to purchase anything but an OEM version
If you buy a canned box from a vendor such as Dell...that OS is an OEM version...and by default support falls on Dell
If you buy the OEM version of software from Newegg..you can migrate that OS as many times as you want....as you make mod's to your system...
I have rolled Newegg OEM Win OS software across as many as 4 mobo changes...and could keep rolling that OS up if I had not switched to a Win7x64 retail OEM...which is residing still on its first mobo home...
If I wanted to buy a new board tomorrow...my present licensed OEM W7x64 would load up and register just fine on the new hardware/board ID...
The only time a problem occurs IS when two machine footprints are looking to update in the same relative time window...in other words...when windows update is sending the same updates to two different machine ID's. MS knows when two machines loaded with the same OS copy are operating independently...as long as you only load and use the software on one machine at a time...zero issues
Always buy OEM off the shelf from vendors such as Newegg unless you want the support contract that comes with the ELU version...which is monumental waste of money given its dubious value and transient shelf life...
