Whats the difference between Windows 2000 CD with lable W2PIS_EN and W2POEM_EN

[Babulmiah]

Hi,

I got a copy of windows 2000 Pro with my PC and the CD volume label (the name shown next to the CD when you put it in your PC) is W2POEM_EN.

I figure this stands for Windows 2000 Pro OEM version in the English language, hence W2P + OEM + EN = W2POEM_EN.

However, I Got a noter copy of win 2000 pro from a friend and his CD is labelled W2PIS_EN. On checking the CD I notice their size (i.e. number of files and folders) is almost exactly the same except for a few bytes difference.

So just out of interest, anyone know whats the difference between them?

Thanks.

Your CD has one more character in the name. :D

I believe the difference is the OS itself. On the OEM CD it may not have the service packs so after Win2k is installed you must install SP1, 2, or 3

On the PIS CD I believe the Service Packs are integrated into the 2000 install so they do not need to be installed seperatly from windows 2000.

The CD may have been created using these instructions:
