I am trying to remove the OS/2 Subsystem components installed to harden my Win2000 server. Although I managed to delete all files in c:winntsystem32os2 and in all its subfolders (by clearing dllcache), I still couldn't delete c:winntsystem32os2 and c:winntsystem32os2dll. I have already completed the necessary removal of the following:
MACHINESOFTWAREMicrosoftOS/2 Subsystem for NT
MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems - deleted OS2 and POSIX entries
Using Sysinternals Process Explorer, although I deleted this folder after closing the filehandle held by Winlogon, the folder reappeared after reboot.
Would appreciate it if anyone could share a solution.
