I realise this post is months old, but I was looking into something similar...

I want to manually reset the XP service pack number.

The following registry change - followed by a restart - achieves this.

@OSSERVICEPACK & all utils I've tested (e.g. XP's systeminfo) report SP1.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows]
; NB "CSDVersion"=dword:00000200 (hex) means SP2. Set to Service Pack 1
"CSDVersion"=dword:00000100
; Requires a restart

BTW, this automatically changes the 'CSDVersion' text here:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]

to: "CSDVersion"="Service Pack 1"

Cheers,

Pete.
