1. Use the Alt + F4 Keyboard Shortcut

2. Open Task Manager as an Administrator

Not running Task Manager as an administrator could prevent you from terminating certain system processes. If that’s the case, use the following steps to open Task Manager with elevated rights and then try to terminate the process again.

1. Click the magnifying icon on the taskbar to open the search menu.
2. TypeTask Manager in the box and selectRun as administrator .
3. When the User Account Control (UAC) prompt appears, selectYes to continue.
4. Right-click on the process you want to terminate and selectEnd task from the context menu.
   

3. Use the Taskkill Command to Terminate the Process

Using the Task Manager isn’t the only way to terminate processes on Windows. If you’re comfortable using Command Prompt, you can run the “taskkill” command to easily stop an unwanted process on Windows.

In order to terminate a process with the taskkill command, you’ll need to know the exact name of the process. To find out, switch to theDetails tab in the Task Manager window and locate the process you want to kill. Note down its name from the first column.

2. TypeCommand Prompt in the box and selectRun as administrator .
3. SelectYes when the User Account Control (UAC) prompt appears.
4. Type the following command and pressEnter to terminate the process. Make sure you replaceProcessName in the following command with the actual name of the process noted earlier.
   taskkill /IM "ProcessName" /T /F
   

Once you run the above command, you should see a confirmation message indicating that the process was terminated successfully.

4. Terminate the Process With WMIC

WMIC (or Windows Management Instrumentation Command-line) is another powerful tool for terminating processes on Windows. Again, you’ll need to know the exact name of the process you want to kill. Once you have that, use the following steps to terminate the process with WMIC.

1. Use any of your preferred methods to open Command Prompt with administrative privileges .
2. Paste the following command in the console, replaceProcessName with the actual name of the process you want to terminate, and pressEnter .
   wmic process where name='processname.exe' delete
   

5. Use a Task Manager Alternative

1. Download Process Explorer on your computer.
2. Double-click theprocexp64.exe to open Process Explorer.
