XP vs. Vista

If you registered the copy that is on the other computer, you can call Microsoft and tell them that the copy on the other computer is no longer in use that you would like to re-use that key.

If you didnt register it, then you need to purchase a copy of Windows to install on that new[er] PC.

is good for that computer only. It is also only good with the OEM disk that came with the system. You can either contact MS or contact the manufacturer of the computer.

OEM SW is non transferable to another system. You will need to purchase a new copy of Windows if you are trying to use a product key from 1 system on a different system.

But the most likely thing is if you got the key off the COA you made a mistake when copping it. If you are using the Install Disc for that Computer the COA should always agree with the Install Disc.

But as others have said here if it is OEM Product it is Illegal to transfer the software and if it was a Recovery Disc it is also unlikely to have the correct drivers for the different system as the Recovery Disc's are slipstreamed with just the drivers for the hardware that they are supplied for.

From the comments, maybe you realised it was dumb? And now, it's even dumber.
