How to run an exe on a school computer? I can't use the command prompt. Is there any way

There are many solutions to your problem, depending on the OS and hardware the school have.

1. Try rebooting and pressing F8 repeatedly to enter Safe Mode (Without networking). Then use Win+R and type cmd.exe to start command prompt. This is pretty risky assuming the teacher is behind you at all times but worth trying.

2. Making your own command prompt. Open notepad and type the following code. Then save to a .bat extension file named as you like.

1. cls 
2. title Command Prompt 
3. :waitc 
4. set /p c= 
5. if %c%==t goto :EOF 
6. if %c%==T goto :EOF 
7. %c% 
8. goto :waitc 

Start the newly created file and you should have an alternative to command prompt. Enter t or T to quickly terminate the cmd terminal to avoid detection.

4. Use Win+R as a alternative to run cmd commands

5. Use Win+R and run the following command

A task manager should pop up. Use this to check for the school control program and force kill it manually or by this script

1. taskkill /f /im programnamehere.exe
