what is the difference?Windows XP Rental version,windows xp upgrade version,corporate version and oem version?I found no difference.Is there any difference in it???

[Vishal Gupta]

There r 3 versions!

1.) OEM
2.) Retail (not Rental )
3.) Volume License (Some ppl call it Corporate by mistake)

1.) OEM versions doesnt hv Upgrade option, they hv only Clean Install option. they has no direct support from Microsoft.. the vendor is responsible. U can't run OEM setup on various h/w. I mean if u hv OEM version for DELL computers, u can't install it on other h/w.

2.) Retail versions hv both options : Clean Install and Upgrade

3.) There's no such thing as "Corporate." That is a term applied exclusively to pirated copies of the Volume Licensed WinXP Pro. Volume Licensed CDs also hv upgrade option. If you have more than five computers then a volume license may be the cheapest & best way.

Volume License Key :
License Key in Volume
hence used by corporates who require multiple copies ( hence also sometimes refered to as corporate edition )
instead of buying diff cd's
they buy one cd and pay for the license keys separately which is effectively cheaper than buyin those many winxp cd's
they also dont require online activation like retail version


OEM versions sometimes have hardware checks thats y can be installed only on ONE system as mentioned
they also contain drivers specific to that pc
oem versions are ALWAYS used in laptops and branded pc's




just a lil addition to what vishaal said

Can it be defeated somehow??? (I read somewhere, 'If it runs, it can be defeated'.)

[Vishal Gupta]

Yes it can be defeated!

HOW???????

Here we go:

For this u hv to edit "Setupp.ini" file in "i386" folder of Windows Setup.

It looks lik following:

[Pid]
ExtraData=xxxxxxxxxxxxxxxx
Pid=xxxxxxxx

The PID value tells the setup, whether its Retail, OEM or Volume Licensed?

HOW????

Break the PID into 2 parts:

First part contains 5 digits
Second part contains rest 3 digits

First 5 digits determine the behavoiur of setup, like Retail, OEM or Volume License.
Last 3 digits determine what key it will acept?

Following are the individual values for all 3 versions:

Retail=> 51882335
OEM=> 82503OEM
Volume License=> 51883270

Here BOLD digits denote the second part, which determines which type of key will it accept?

So the conclusion is that!

If u want that a Retail Setup CD accept OEM key, the simply change the PID to:

51882OEM

Or OEM version support Retail Key, then PID should be:

82503335

Thats it!

PS: The first 5 digits of PID may be different from setup to setup but last 3 digits will be same in all setup.
This tutorial is not Illegal, I read it in DIGIT edition.
