I have had varying results with the effect of SP2 on the registry and
uninstall directories, but I can positively state that winlogon.exe
(installed by Q285851) was left in place by SP2 in all cases.
By the way, I thought the Microsoft page to which you refer is a bit
misleading:

1. SP2 plus Q294391 supersedes Q287397
2. There is a roll-up IIS patch Q293826
3. SP2 updates IE5, so if you are running IE5.5SP1 you still need to
apply Q283908, Q286045 and Q295106 (and probably you want to install the
scripting update)

Subject: Windows 2000 SP2 uninstalls Pre-SP3 Security Patches

I believe that all Pre_SP3 Security Patches are automatically removed by
installing Window 2000 SP2. I've verified that the Pre-SP3 QXXXXXX are
not listed under the following registry key:
HKEY_LOCAL_MACHINE
\Software\Microsoft\WindowsNT\CurrentVersion\Hotfix\Q######

after installing SP2.

If you do a search by Product and Service Pack at
<http://www.microsoft.com/technet/security/current.asp> for Security
Patches using:
Product: Windows 2000 Adv. Server
Service Pack: Windows 2000 Service Pack 2

You'll find that MS will list a number of security patches that need to
be installed after installing Window 2000 SP2. I had those same
security patches installed prior to the installation of Windows 2000 SP2
- but now I need to re-install them all?? The same goes for IIS 5.0
patches.

I can not confirm these findings anywhere on Microsoft's web site or in
the Readme's, but using the registry as my guide, the Pre-SP3 patches
have been uninstalled during the install of Windows Service Pack 2.

Anyone else see the same problem?
