How do you change the build number in XP?

Post by Memphis »

As a stupid experiment, i will try to install service pack 3 on build 2542, however this service pack requires a build number of 2600 (the rtm build number) is there a way to change the build number and trick the installer? i think its possible because of this build being a few days before the rtm release.

Start -> Run -> regedit -> OK
This will open Registry Editor
Now you must go to HKEY_LOCAL_MACHINE -> SOFTWARE ->Microsoft -> Windows NT -> CurrentVersion
Then you should find the following values:

Code: Select all

CurrentBuild
CSDVersion
BuildLab
Version
Double click on them and change the value.

unless it checks in kernel, then you have to hex edit it :P
(and it usually does)

I remember doing the registry method but it reset on restart
