    After reading that not only these subsystems are not commonly used but also they can slow down the system, I decided to remove them. I tried to delete the winntsystem32os2 folder but had to do it in Safe Mode. Also I tried to rename 3 files in the winntsystem32 but they kept coming back and are still around. Finally as indicated in the article at LabMice.net (Windows 2000 Security Checklist), I made changes to the registry (see below). However, Windows 2000 keeps putting back some of these keys in the registry. What should I do to get rid of these subsystems?
    Thanks. Dom

    Use the Registry Editor to remove the following registry entries:

    Key:
    HKEY_LOCAL_MACHINESOFTWARE

    Subkey:
    MicrosoftOS/2 Subsystem for NT

    Entry:
    delete all subkeys

    ——————————————————————————–

    Key:
    HKEY_LOCAL_MACHINESYSTEM

    Subkey:
    CurrentControlSetControlSession ManagerEnvironment

    Entry:
    Os2LibPath

    Value:
    delete entry

    ——————————————————————————–

    Key:
    HKEY_LOCAL_MACHINESYSTEM

    Subkey:
    CurrentControlSetControlSession ManagerSubSystems

    Entry:
    Optional

    Values:
