Correct. The retailer's description wasn't specific; it only stated that it was "branded." Well, I thought that meant it had the retailer's brand, which would have been fine. Now I know.
I have full retail, upgrade and OEM versions. In fact, here is my WinXP pro OEM Dell branded disc ( I build all of my own machines): http://www.tafool.com/Stuff/DellCD0001.JPG The OEM install is fully validated through the MS Genuine Advantage Tool (which all installs must go through) and updates just fine. As long as your COA was sealed the install will be fine and you won't have any problems. TA
