Hello Experts!!!
  I'm getting a error message when a computer boots up.
winlogon.exe - Unable to locate component
This application has failed to start because sfc_os.dll was not found. Re-installing the application may fix this problem.
 Is there a solution for this? If I click OK, the box goes away and the computer starts and seems to run fine.
                                               Thanks for the help......Don

It may be something in the registry looking for sfc_os.dll .

I would go to Start/ Run , type in regedit and do a search for sfc_os.dll and delete all that you find.

Keep hiting F3 key to search through registry.


All so look here.

DONT DELETE THAT DLL, it belongs to Windows File Protection.....

See if there is a copy in the C:\Windows\System32\DLLCache folder, and copy one to the C:\Windows\SYSTEM32 directory....

Or get one from a similar machine.....

Have you done a Search for the file? It should be located at: C:\Windows\System32
If not, then: Start>Run>type CMD>press OK
At the blinking cursor type sfc /scannow (space between c and /)
Have your XP reinstallation CD ready to insert.
sfc = system file checker, it scans your harddrive for corrupt or missing system
files and ask you if you want to replace/install them.

Ok....I figured it out. The sfc_os.dll file that I made a copy of...I put in the wrong folder. I went back and took a closer look. The file goes in the Windows/system32 folder. After that all is well. Thanks for your time............          Don
