Explorer.exe won’t load following a reboot

Recently encountered problems getting Windows Explorer shell to load in Windows XP after cleaning a spyware infection.  I found there are two registry keys that are critical in relation to loading explorer on boot,  you should check them first if you even encounter a problem getting Explorer.exe to load.

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon


shell=”explorer.exe”


HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon

userinit=C:windowssystem32userinit.exe

Watch out for trailing comma’s on userinit.exe  (userinit.exe, ) as this is where malware likes to insert itself to load during windows startup.
