Difference Between XP Upgrade And Full Version
Both versions are identical except for the fact the upgrade version requires a Windows 98/ME/2000 installation CD if you desire to perform a "clean install. A "full version" does not have this requirement. However, the cheaper "OEM full version" cannot upgrade over an existing Windows installation....only "retail full versions" can.
The software itself is identical. Only the rules for how it can be used are different.
The full version can be used for either an upgrade or clean installation. The upgrade can too, but for a clean installation it requires that you have a previous qualifying version's CD to insert as proof of of ownership when prompted to do so.
Also note that there is a third type--an OEM version. Many people confuse this with the full version. However an OEM version can not do an upgrade at all.
*** Of course there are exceptions where an OEM version can do an upgrade. Reason being, there are a few flavors of OEM versions around eg large PC makers sometimes sell/provide these type of "special OEM" disks with their PCs.
What do you mean by an unlicensed version of 2k? Are you using a beta version? I am running 2k pro, I have never registered it online and I have no problem getting updates. Sorry I don't mean to be nosy but curiosity has got the better of me.
You can download the updates and install from your hard drive.
