OEN - the second post was accurate but is there a funny?
Oddly Enwrapped Machinery 😛
Anyways my penceworth - OEN can also be like in the slim line HP iDesign machine - that would have had oen OS etc on it - it was lipped into a hidden partition,,,,
So even buying a new box with all the frills you may get "OED'd"....
More verobosely the point is you buy a bunch of stuff from a big outifit (they're guys like DEll or HP) and because of who they are and what they want they get cheaper biuts like the OS and addpons, bundle them up - then sell the box for 3-4 times what it cost them,.....
You can buy personal oem if buildingtoo - just need to be slightly cautious about what you need and what you'll get - the coe softwate ust be the same essentially, personal worst case wa an OEM XP machine supplied no Xp CD (YEs they can do that!) so when disc goes I have to buy both fisc and another XP CD *unless I'm clever prepared, and pesimisstic enough to ghost my drive,,, even then not sure that flies!)
Hope I helped explain - even if at too much length
