Fantastic, egorz

That takes us over the 100 mark.

btw for your own records a hotfix has sneaked into your list (954550)

And some additional...

957095
958469
958655
961118

and maybe
961742
973768

953356 is for SP2 only.

Yep In its KBA it looks like the technical hotfix, however it was completely included in .NetFX 3.5 SP1

2Petr
KB958469 - Update for RDP client v5.2 - XP SP3 already has included RDP client v6.0
KB961742 - technical hotfix (update for NT Logon) and there is no KBA for it

This is interesting, http://support.microsoft.com/kb/958469/en clearly states that XP SP3 can contain RDC 5.2 or 6.1 and WindowsXP-KB958469-x86-ENU.exe really contains SP3GDR and SP3QFE folders only.

Good work guys, list updated.
