To access the command prompt, you can type "cmd" in the search bar on your computer and press enter. Alternatively, you can press the Windows key + R and type "cmd" in the run box.
There could be several reasons why the command prompt is not working, such as corrupted system files, outdated drivers, or a virus. Try restarting your computer and running a virus scan to see if that resolves the issue. If not, you may need to troubleshoot further or seek technical support.
To navigate through folders in the command prompt, you can use the "cd" command followed by the name of the folder you want to access. You can also use "cd.." to go up one level in the directory or "cd\" to go back to the root directory.
You can run a program using the command prompt by typing the name of the program followed by its file extension. For example, to run a program called "myprogram.exe", you would type "myprogram.exe" in the command prompt and press enter.
If you are encountering errors in the command prompt, it is best to first check the syntax of your command and make sure it is typed correctly. You can also try running the command as an administrator or checking for any updates or patches for your operating system. If the issue persists, you may need to seek further assistance or consult online resources for troubleshooting tips.
