Classroom management software running on student machines often restricts system access during lessons. This guide covers methods for terminating these processes and restoring normal system functionality.

Prerequisites

Be aware of the consequences before proceeding:

• You will not receive instructor screen shares
• File transfers from the teacher workstation will fail
• Network connectivity may be disrupted
• The instructor console will register a disconnection

Method 1: Network Cable Disconnection

The most straightforward approach involves physically disconnecting the network cable from the computer.

Implementation:

Locate the Ethernet port on your machine and remove the cable directly.

Pros:

• No technical knowledge required
• Instant reconnection when cable is restored

Cons:

• Cables are often hidden in hard-to-reach locations
• Difficult to remove and reconnect
• Instructor receives immediate disconnection alert

Method 2: Process Termination via Command Line

This method uses the Windows command interpreter to terminate the management software process.

Process Identification:

Classroom control applications typically run as studentmain.exe or similar executables. Standard task manager operations will fail with access denied errors.

Execution:

Open Command Prompt with administrator privileges and execute:

taskkill /F /IM studentmain.exe

The /F flag forces termination, and /IM specifies the image name of the process.

Pros:

• Quick execution
• High success rate

Cons:

• Requires command-line familiarity
• Recovery may be difficult if shortcuts are removed

Batch Script Alternative:

To avoid repeated command entry, create a batch file on removable media:

@echo off
taskkill /F /IM studentmain.exe
pause

Save with a .bat extension and run with elevated privileges when needed.

Reconnecting to the Control System

After gaining system access, restoration depends on your chosen method:

Network Disconnection: Reinsert the Ethernet cable. The software typically auto-reconnects within seconds.

Process Termination: Locate the software shortcut or executable. Common paths include:

C:\Program Files (x86)\Mythware\极域课堂管理系统软件v6.x\

The executable may be named studentmain.exe. Note the full path before termination for easier restoration.

Bypassing Screen Lock Restrictions

When the instructor locks your display, standard input methods become unresponsive.

Windows 7

1. Press Win + L to lock the workstation
2. Press Alt + W to switch users
3. Select your account and log in
4. Durring the brief unlock window, immediately open Command Prompt
5. Enter the termination command
6. If locked again before completion, repeat the process

Windows 10

1. Locate the Sleep button on your keyboard
2. Press Sleep to suspend the system
3. Wake the computer using the power button
4. Open Command Prompt during the unlock period
5. Execute the termination command
6. Retry from step 1 if necessary

Handling USB Port Restrictions

Some classroom environments block USB storage access. To resolve this, open Command Prompt and run:

sc stop tdfilefilter

This command stops the file filter driver service responsible for USB restrictions. Use sc start tdfilefilter to re-enable restrictions when needed.
