Converting OEM into VLK (site license)

[blub3636]

Hiya again,
I successfully managed to convert both xp home sp3 oem & xp pro sp3 oem into vlk images and to deactivate the wpa issue.
By transfering the earlier named files accross into my nlite temporay folder.
One issuse still remains though.
Since I converted both images into VLK editions they both require VLK key's.
I do want to continue to use actual propper liscense's - if possible.
Therefore is it somehow possible to exchange the key after installing the image?And to maintan the deactived wpa status?
thx, blub3636
