Fix A command is not recognized as an internal or external command Error in Windows 10
If you are constantly using programs like CMD or DISM directly from the Run prompt, you might have wondered how they launched instantly and how is it that the Windows operating system is able to find them right away. For instance, when you create a shortcut of a program, the shortcut knows where exactly the program is located and launches it quickly.
The Windows operating system keeps a list of path where the most common system programs are located so when you use the Run prompt, it opens easily. The list kept by Windows is called the Windows Environment Variables. If something goes wrong with this list, the programs won’t work. So in this guide, you will be guided on how you can troubleshoot the problem where any command you use is not recognized as an internal or external command, operable program or batch file.
Before you start troubleshooting the problem, you need to make sure that the program you are trying to run really exists. In fact, this can also happen to the Run program which is pulled up using the Win + R shortcut. To check, go to C:WindowsSystem32 and there, check if the program exists or not or you can also try searching for the EXE in the System 32 folder. After making sure that the program exists, refer to the instructions given below.
Modify the Windows Environment Variables:
Step 1: Tap the Win + X keys and then select System. After that, it will open the section where you can see all the properties on your computer.
Step 2: Next, select the Advanced system setting located on the left pane and click on the Environment Variables.
Step 3: After that, locate Path under the System Variables and select EDIT.
Step 4: Before you edit, you need to copy the entire string and paste it into the Notepad app so that in case something went wrong, you can paste it back.
Step 5: Next, look for the directory path, “C:WindowsSystem32”. If you can’t find it, try adding a semi-colon at the end.
Step 6: Afterwards, click OK to save the changes made and then exit.
Step 7: Now restart your computer as all the paths are picked up when your computer restarts.
Note: Now all you have to do is to try executing the programs once again – the ones where you got the error, “ is not recognized as an internal or external command, operable program or batch file” every time you open them and then see if you can now open these programs or not.
If the problem is still not fixed and you’re still getting the “ is not recognized as an internal or external command, operable program or batch file” error every time you open a program, then the problem might be caused by something else entirely. To fix it, you can try using a one-click solution known as Restoro. This program is a useful tool that could repair corrupted registries and optimize your PC’s overall performance.
