Userenv : Event 1041

On a Windows 2003 server i came across the following errors in the event log:

Windows cannot query DllName registry entry for {CF7639F3-ABA2-41DB-97F2-81E2C5DBFC5D} and it will not be loaded. This is most likely caused by a faulty registration.

Windows cannot query DllName registry entry for {7B849a69-220F-451E-B3FE-2CB811AF94AE} and it will not be loaded. This is most likely caused by a faulty registration.

To resolve this issue simply delete the following registry keys:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{7B849a69-220F-451E-B3FE-2CB811AF94AE}]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\GPExtensions\{7B849a69-220F-451E-B3FE-2CB811AF94AE}]

This issue is caused by the uninstaller not removing all keys created during the installation of IE8.
