I just checked a XP-sp2 and it doesn't have that key either.
A regular 2k3-sp2 has this ke and here it looks like
Windows Registry Editor Version 5.00 [http://HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent] [http://HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\User Agent\Post Platform] ".NET CLR 1.1.4322"="" ".NET CLR 2.0.50727"="" ".NET CLR 3.0.04506.648"=""
As this is a LiveCD I can actually populate that key with whatever suits best.
Do you any suggestions ?
Thank you
