When you try to run a command in Windows 11 and see the error message 'Request' is not recognized as an internal or external command, it can be confusing. This issue usually means Windows does not know where to find the program or script you want to run. It can happen with any command prompt or terminal command.

This error stops your command from executing properly. But don’t worry, fixing it is often straightforward once you understand the cause. In most cases, it relates to how Windows searches for commands.

In this guide, we will walk through simple, step-by-step methods to resolve this error. Each step is explained in detail so even beginners can follow along easily.

By the end, you will know how to troubleshoot and fix this problem so your commands run smoothly again.

Quick Note: Before You Begin

Before diving into fixes, here are some quick checks to make sure you are on the right track:

• Check your command spelling: Even a small typo can cause this error.
• Confirm the program is installed: Make sure the software or tool you want to run is actually installed on your PC.
• Use the correct command prompt: Some commands only work in Command Prompt (CMD), others in PowerShell or Windows Terminal.
• Run as Administrator: Some commands require elevated permissions to work properly.

Step 1: Verify the Command Name and Spelling

The simplest cause of this error is a typo in the command. For example, typing ipconfing instead of ipconfig will trigger the error.

How to check:

• Carefully retype the command.
• Use copy-paste from a trusted source if possible.
• Make sure there are no extra spaces or special characters.

Correct spelling ensures Windows looks for the right executable and avoids unnecessary troubleshooting.

Step 2: Confirm the Software or Tool Is Installed

If the command corresponds to a program or utility, Windows needs that program installed to recognize it.

How to check:

• Open Settings > Apps > Installed apps and look for your program.
• Alternatively, search for the program using the Start menu.
• If it’s missing, download and install it from the official source.

Without installation, Windows cannot run the command, so this step is crucial.

Step 3: Check the System PATH Environment Variable

Windows uses the PATH environment variable to find programs when you type a command. If the folder containing your program is not in PATH, Windows won’t recognize the command.

How to Check and Edit PATH

1. Press Windows + S and type Environment Variables.
2. Select Edit the system environment variables.
3. In the System Properties window, click on the Environment Variables button.
4. Under System variables, find and select Path, then click Edit.
5. Look for the folder path where your program or command executable is located.
6. If it’s missing, click New and add the full path to the folder.
7. Click OK on all windows to save changes.

Why this matters: Adding the program folder to PATH tells Windows where to find your command without typing the full file path every time.

Step 4: Run the Command with the Full Path

If you don’t want to modify your PATH or need a quick test, you can run the command by typing its full location.

Example:

"C:Program FilesYourAppapp.exe" argument1 argument2

This method bypasses PATH entirely by pointing Windows directly to the executable.

Step 5: Use the Correct Command Prompt or Terminal

Some commands only work in specific command environments:

• CMD (Command Prompt) – Older commands and batch scripts.
• PowerShell – More powerful, supports different syntax.
• Windows Terminal – A modern app supporting CMD, PowerShell, and more.

If your command isn’t recognized, try switching terminals. For example, open PowerShell and try again.

Step 6: Restart Your Computer

After making changes to environment variables or installing new software, a restart ensures Windows applies those changes properly.

Sometimes, simply restarting fixes the error without further action.

Alternative Methods and Advanced Options

Use the where Command

To check if Windows can find your command, open Command Prompt and type:

where commandname

This will show the full path of the command if it exists in your PATH. If nothing appears, Windows cannot find it.

Reinstall or Repair the Software

If the command belongs to a specific program and still fails, try reinstalling or repairing the installation. This can fix corrupted files or missing executables.

Check for Malware or System Issues

Rarely, malware or system corruption can cause commands to disappear or fail. Running a virus scan and using tools like sfc /scannow can help detect and fix system problems.

Frequently Asked Questions (FAQs)

Why does Windows say a command is not recognized?

Usually because the command is misspelled, the program is not installed, or the folder containing the program is not in the system PATH.

How do I add a folder to the PATH variable?

Go to System Properties > Environment Variables > System variables > Path > Edit, then add the folder path and save.

Can I run commands without modifying PATH?

Yes, by typing the full path to the executable or running commands from their installation folder.

What if the command works on another PC but not mine?

Check if the program is installed on your PC and if PATH includes its folder. Also verify you are using the same command prompt type.

Does running as Administrator help?

Some commands require administrative rights. Right-click your terminal app and choose “Run as administrator” to test.

When Nothing Works

If you have tried all the steps above and continue to see the error, consider these final options:

• Consult official documentation: Visit the software or command’s official website for troubleshooting guides.
• Use Microsoft support forums: Search or post your issue on the Microsoft Community forums.
• Reset your system environment variables: Advanced users can reset PATH to default, but be careful as it affects many programs.
• Perform a system restore: Restore your PC to a previous point where commands were working.

Conclusion

The 'not recognized as an internal or external command' error in Windows 11 is a common and fixable issue. By carefully checking your command spelling, confirming software installation, and ensuring your system PATH is correctly set, you can solve most problems quickly.

Remember to restart your PC after changes and try running commands from different terminals if needed. Using the full path to executables can also help isolate the issue.

If you encounter persistent problems, don’t hesitate to seek help from official resources or reinstall the software. With these steps, you will be able to run your commands smoothly and get back to work.
