Windows 7 Tab Completion for Command Line

[Meflakcannon]

I know Tab Completion is enabled by default for the command line interface, however for whatever reason It has been disabled on my laptop.

I have checked [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor]
However setting the Completion Character to 9 or in some cases 64 (Both in Decimal) fails to work
I also tried setting the PathCompeltionChar to both 9 and 64

Nothing has worked, Are there any other solutions or a full reset to settings for the Command line interface?

If tab completion is not working on your laptop despite trying the registry edits you mentioned, there are a few other steps you can take to troubleshoot and potentially fix the issue. Here are some solutions you can try:

Additional Solutions for Tab Completion Issue in Command Line Interface:​

1. Check Registry Keys:
   • Confirm that you are modifying the correct registry keys and values. Ensure that you are editing the keys at:
     • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor
     • Verify that you are setting the correct values for CompletionChar and PathCompletionChar.
   []User-Specific Settings:
   • Check if there are any user-specific settings that might be overriding the system-wide settings. Look in the registry under HKEY_CURRENT_USER for any conflicting settings related to command line completion.
   []System File Checker (SFC) Scan:
   • Run a System File Checker scan to check for and repair missing or corrupted system files that could be causing the issue.
     • Open Command Prompt as an administrator and run: sfc /scannow
   []Command Prompt Properties:
   • Check the properties of the Command Prompt shortcut for any customization that might override the default behavior.
     • Right-click on the Command Prompt shortcut, go to Properties, and ensure that nothing is inhibiting tab completion.
   []Check Group Policies:
   • There might be group policies in place that are preventing tab completion. Check Group Policy settings that might affect Command Prompt behavior.
   []Reset Command Prompt Settings:
   • To reset Command Prompt settings to default, you can try creating a new user account on your system and check if tab completion works for the new user. If it does, you may consider migrating your files to the new account.
   []Third-Party Software Interference:
   • Ensure that third-party software or utilities aren't interfering with Command Prompt functionality. Disable them temporarily to see if tab completion starts working.

     Full Reset of Command Line Interface Settings:​

     If none of the above solutions work, and you still want to perform a full reset of Command Line Interface settings, you can try resetting the Command Prompt using the following steps:
   []Press Win + X and select "Windows Terminal (Admin)". []In the Windows Terminal window, run the following command to reset Command Prompt settings:

    reg delete HKEY_CURRENT_USER\Console
