Changing OEM to Retail/Upgrade to Full?

[penguin7009]

Fellow techguiders, If changing the Pid numbers, OEM,270, and 335 makes XP into OEM, Volumn License and Retail, respectively.  What determines if it is an upgrade or a full install?

Any one have any ideas.  The article elsewhere in these forums dealing with the above type of "key" to use works.  By copying the cd to your harddrive and changing the "setupp.ini" file to one of the last three digits above will change the type of key the cd will accept when installing.

What change would allow one to make it Full Install or Upgrade?

Thanks, penguin7009 http://images.thetechguide.com/forum/public/style_emoticons/<#EMO_DIR#>/rolleyes.gif\' class=\'bbc_emoticon\' alt=\':rolleyes:\' />

The numbers you quoted, 270, 335, oem, only determine what type of key you have to use. Volume, Retail, Oem. Of those Oem will only do a full install, not an upgrade. To actually change a Retail disk to lets say a Retail you would have to change the 82503 to 51882 and the oem to 335, then you could do full install or upgrade. The volume edition requires the corp files to make it work, you cannot just change the numbers.
Hope I helped you,

Thanks, Ron.  I have been able to change the type of key my ligitament copy of XP Pro will accept when installing by changing the last three numbers as above.  I was just wondering if one could change a ligitemate retail version from a "clean install" only to an "upgrade install" also, by just changing, say,  a number as in the "pid" number.

From your post, it seems that more than a "digit" change would be needed.

Thanks for the post
