In Windows 10, Why Did I Get This “reg” Command Prompt Error?

Question

In Windows 10, why did I get this “reg” Command Prompt error?

reg : The term 'reg' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is correct and try again.

Answer 1

Hello,

The following are possible causes and solutions:

Path problems: If you are attempting to run a custom script or program called reg that is located in a different directory, you will need to provide the full path or add the path to the system's PATH environment variable.

Command Prompt Privileges: Some reg command operations may require administrator privileges. Try running the command prompt as an administrator and then running the reg command again.

System file corruption: If the reg.exe file itself is corrupt or missing, the command will not work properly. You can try using the System File Checker (SFC) to repair the corrupted system file. Open a command prompt (as administrator) and type sfc /scannow and press Enter.

Environment Variable Problems: Sometimes environment variable settings may cause commands to not be recognized correctly. Verify that your system PATH environment variable contains the Windows system directory (e.g. C:\Windows\System32).

Third-party software conflicts: Certain security software or other third-party applications may interfere with the proper functioning of command-line tools. Try temporarily disabling these softwares to see if the problem persists.

Never mind. I fixed the environment variable issue. The “reg.exe” file is located in the “System32” directory.
