Power-related failures on Windows PCs come in many forms. Sometimes hibernating your computer might (wrongly) stop it. And other times it just won’t stop. As reported by some Windows 10 users, there are also cases where a PC is turned off but immediately turns back on within seconds. If you are experiencing this issue, the troubleshooting solutions compiled in this guide will help you resolve the issue.
Ideally, turning your PC on or off should be the easiest thing to do. However, you can trust Windows to present one issue or another during the process. Your PC would restart automatically after shutdown due to reasons ranging from outdated operating system to configuration hiccups. Without further ado, let’s get to the solution.
1. Disable fast startup
Quick Start is a feature designed by Microsoft to help your Windows computer start up faster. It has its advantages, but the functionality sometimes results in malfunctions related to stopping and starting. If your computer doesn’t stay off after you turn it off, you can turn off fast startup and see if that helps. Here’s how.
Step 1: Launch the Run dialog box using the “Windows Key + R” keyboard shortcut. Type control in the dialog box and press OK (or press Enter on your keyboard).
This will launch the Windows Control Panel.
2nd step: Next, tap on the View by drop-down option and select Large icons.
Step 3: Click Power Options.
Step 4: Click “Choose what the power button does” from the Power Options menu.
Step 5: The quick start settings are always on by default and locked. To deactivate it, you must unlock it by tapping on the option “Change settings currently unavailable”.
Step 6: Now turn off the option “ Enable fast startup (recommended) ” and hit the Save changes button to continue.
Shut down your computer after that and check whether it restarts automatically or not.
2. Check the registry configuration
PowerdownAfterShutdown is a registry key / file that helps keep your Windows PC powered off after shutting it down. If your device restarts automatically each time you turn it off, check that the PowerdownAfterShutdown the key is correctly configured (activated).
Step 1: Launch the Windows quick access menu using the keyboard shortcut “Windows Key + X” and select “Command Prompt (Admin)”.
Grant administrative privileges to the app when prompted.
2nd step: Paste the code below into the console and hit enter.
REG QUERY "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon" /v PowerdownAfterShutdown
If the value of PowerdownAfterShutdown key is zero (0), that means it is disabled.
Go to step 3 to activate it.
Step 3: Paste the code below into the console and hit enter.
REG ADD "HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWinlogon" /v PowerDownAfterShutdown /d 1
Step 4: You will be prompted to confirm and replace the previous value of the registry key. Type y and press Enter to continue.
Running this code will change the value of the PowerdownAfterShutdown registry key 0 to 1. Your computer should now be left off each time you shut it down.
3. Disable automatic restart after system failure
The Windows 10 operating system is configured, by default, to automatically reboot if your computer experiences a system crash while performing an action. While this setup is useful and helps correct some system errors, it can cause your PC to hang in an endless reboot loop after shutdown. Try disabling automatic restart after system failure and see if that fixes the problem.
Step 1: Launch the Run dialog box using the “Windows Key + R” keyboard shortcut. Type sysdm.cpl in the dialog box and press OK (or press Enter on your keyboard).
This will launch your PC’s System Properties window.
2nd step: Go to the Advanced tab and select press the Settings button in the “Startup and Recovery” section.
Step 3: Uncheck the Automatically restart box and press OK to continue.
Step 4: Finally, press OK in the System Properties window to save the changes made.
4. Update Windows
If the above fixes don’t prevent your Windows PC from restarting automatically after shutdown, you need to try a solution that works for other Windows users: update Windows 10.
All versions (new and old) of Windows 10 have unique bugs that disrupt certain system processes. You never know, this problem may simply be caused by a bug specific to the Windows 10 version installed on your computer. Go to Settings> Updates & Security> Windows Update and download the latest available update.
Mainly, the methods mentioned above should prevent your Windows 10 PC from restarting automatically after shutdown. And apart from updating your computer’s operating system, you also need to make sure that the drivers are up to date. Finally, verify that your computer does not have an automatic restart program.
