explorer does not start on boot

[Enrique]

I have a user that logs on to a Windows XP box but Explorer.exe does not
start so I have to manually start it. If I log on with a different profile
(admin and non-admin account), Explorer.exe will start. What could be
causing this within that profile?

Thanks,
Enrique

Note: This problem can be caused by ‘malware’.

However, try clicking Start > Run, type regedit and press Enter. In the left
pane navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon.

In the right pane, make sure there is a REG_SZ named Shell and it has a
value of "explorer.exe" (no quotation marks). If it’s not there, create it by
clicking Edit > New > String Value then right-click it and key in
explorer.exe then restart the computer.
