I bet it didn't activate.
The only difference between oem and retail is the fancy box. Other than that they are the same. You can buy an oem cd if you buy something that's on M$ approved parts list. Not a brand name just a device like a vid card. You get all the same support as if you bought a retail. The colour of the cd is different and the key falls in a different catagory but these are not things for the user to be concerned about.

This you are in error about. You can reinstall oem like retail 6 times before you have to phone for activation. An alternate solution is to retire the cd for 6 months. M$ wipes inactive files after 6 months of non use.
