How to restore missing: regedit and/or msconfig files

sometimes malwares rename/delete : regedit/msconfig.

Make sure you still have the executable files:

C:\WINDOWS\regedit.exe
and
C:\WINDOWS\PCHealth\HelpCtr\Binaries\MSConfig.exe


If you dont have then restore it in the given way:-

put the xp cd and type (where X is the CD drive name):

EXPAND -R X:\I386\MSCONFIG.EX_ C:\WINDOWS\PCHEALTH\HELPCTR\BINARIES

That should restore MSConfig.exe to your Windows. IF MSConfig.exe is already there and you still can’t launch MSCONFIG from Run command, then the reference to the path within the registry may be wrong. Check this location in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\MSCONFIG.EXE

In the right pane, next to Default, it should show:

C:\WINDOWS\PCHealth\HelpCtr\Binaries\MSConfig.exe
