A User stealthsettings.com It drew my attention to a fall that appeared in Windows XP Following an order given in Run:

The main causes of this error are, most of the time, certain virus which I delete msconfig, regedit or other commands in the run.
How can you recover msconfig.exe in xp if it has been deleted from Run
1.- Before starting recovery msconfig.exe, you must make sure that it is still on MAINTAINED. It should be in C:WindowsPCHealthHelpCtrBinaries. If msconfig.exe is not in that folder, then you need The installation CD Al Windows XP. Open one Command Prompt, insert the CD in CD-ROM, and then Tut the command:
EXPAND -R D:I386MSCONFIG.EX_ C:WINDOWSPCHEALTHHELPCTRBINARIES
Or, if you still have a computer with Windows XP At hand, it is easier to copy msconfig.exe on the folder Binaries.
2.- In case msconfig.exe is not missing from the Binaries folder, but you cannot launch it from Run, then the problem is from registry. Check the way HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionApp PathsMSCONFIG.EXE. In the right panel, the value Default should be C:WINDOWSPCHealthHelpCtrBinariesMSConfig.exe.

Once you correct the registers, the MSConfig command can be launched from Run without problems.
