How to Cancel a Shutdown on Windows 10

Using Command Prompt (If Shutdown is Scheduled):
- Press Windows + R to open the Run dialog.
- Type cmd and press Enter to open the Command Prompt.
- Type the following command and press Enter:
```
shutdown -a
```
- This will cancel any scheduled shutdown or restart.

Using Task Manager (If Shutdown is Ongoing):
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Processes tab and look for shutdown.exe (if it’s listed).
- Select it and click End Task to stop the shutdown process.
Cancel Shutdown During Countdown:
- If you initiated the shutdown manually and the system shows the countdown, you can press Ctrl + C in the Command Prompt (if opened) to cancel it.
- Alternatively, you can immediately use shutdown -a in the Command Prompt if it was scheduled using that method.

By using these steps, you can quickly cancel a shutdown in Windows 10 if you change your mind before the system powers off.
