Updates fail after upgrade from XP-Home to XP-Pro

After making an upgrade-installation of XP-Pro, all updates keep failing.
Is it possible, that XP-Pro doesn't know, that XP-Home already had those
updates?
If yes, how do I make windows know it's correct patch-condition?

http://windowssecrets.com/comp/070927/#story1 did the trick.
It seems, that an upgrade is causing the same problem, as the use of the
repair-console.

See http://support.microsoft.com/kb/916259/en-us
You may find downloading the Standalone version of Windows Update Agent 3.0,
saving the WindowsUpdateAgent30-x86.exe in a folder named "C:\Downloads" and
executing "C:\Downloads\WindowsUpdateAgent30-x86.exe" /wuforce (including
*all* blanks and quotes!) under "Run" in the Start menu easier:
http://download.windowsupdate.com/v7...gent30-x86.exe

Afterwards revisit the Windows Update site, let the offered update for WUA3.0
install and see the updates downloading and installing fine.

Bye,
