How do you stop the error 'reg' is not recognized as an internal or external command operable program or batch file?

To resolve this, ensure that you are using the command prompt with administrative privileges, as some commands require elevated permissions. If the issue persists, check that the Windows Registry Editor (reg.exe) is present in the C:\Windows\System32 directory, and if not, you may need to repair your Windows installation or restore the missing file. Lastly, verify that your system's PATH variable includes C:\Windows\System32.
