How to Fix Windows 11 Restarts/Reboots Automatically

Do note that there’s no universal fix as such. You will have to try out each of the below-mentioned workarounds and see which one works best in your favor. So with that in mind, let’s get started.

FIX 1: Update Group Policies

Upon installing a new feature or quality update, sometimes the Group Policies might not get updated. As a result, the old policy files could create a conflict with the newer update. So there are two approaches that you could take to rectify this issue- either wait for the next update to be released which will automatically update these policy files, or manually update these files right away. As of now, let’s proceed ahead with the latter method, i.e. manually updating the Group Policies files. Here’s how it could be done:

Head over to the Start menu, search CMD, and launch it as an administrator.
After that, type in the below command and hit Enter:
```
gpupdate
```
Then enter the following command to clear the screen
```
cls
```
Now check if fixes the Windows 11 automatically restarts/reboots issue.

FIX 2: Using CHKDSK Command

The aforementioned issue could also be caused in case there’s a bad sector in this disk or if some hard disk-related files have got corrupted. In that case, you should consider using the Check Disk or CHKDSK command. It will automatically scan for all the disk-related issues and would subsequently fix them as well.

So launch the Command Prompt window as an admin and then execute the below command:
```
chkdsk /x /f /r
```
The scanning might take a few minutes. Once done, verify whether the Windows 11 automatically restarts/reboots issue has been fixed or not.

FIX 3: Use SFC and DISM Command

System File Checker and Deployment Image Servicing and Management are two command-line utility tools that scan for the corrupt Windows files and then replace them with their working counterpart. The major difference between the two is whereas the SFC replaces the corrupt files with the working ones from the cached directory on your PC, DISM does so by downloading the working files from the online Microsoft servers. And as of now, we would be making use of both these tools to fix the underlying issue. Follow along.

To begin with, right-click on the Start Menu and select Windows Terminal (Admin).
Then click on the down arrow present next to the new tab icon and select Command Prompt from the list.
Once the CMD window is opened, copy-paste the below command to open the SFC Tool:
```
sfc /scannow
```
Once the SFC Scanning is complete, it’s time to use the DISM Tool. So copy-paste the below command:
```
DISM /Online /Cleanup-Image /RestoreHealth
```
Once both these commands have been executed, verify if it ends up fixing the Windows 11 automatically restarts/reboots issue.

FIX 4: Update GPU Drivers

Using old or outdated graphics drivers could result in quite a few issues, including the one that we are currently dealing with. Therefore, it is recommended to update these drivers to the latest builds, which could be done as follows:

Use the Windows+X shortcut keys and select Device Manager from the menu that appears.
Then expand the Display Adapter section, right-click on your dedicated graphics card, and select Update Drivers.
After that, click on Search automatically for updated drivers.
Windows will search online for the latest GPU drivers and shall subsequently download and install them as well.

Once done, reboot your PC and then check if the Windows 11 automatically restarts issue has been fixed or not.

FIX 5: Via Registry Editor

In some instances, the OS forces the system to automatically restart itself as soon as a new update is installed. But as of now, we need to prevent the OS from performing this restart. To do so, we will be using Registry Editor and the NoAutoRebootWithLoggedOnUser key. So proceed ahead with the instructions:

To begin with, bring up the Run dialog box via Windows+R shortcut keys.
Then type in the below command and hit Enter. This shall launch the Registry Editor.
```
regedit
```
Now copy-paste the below command in the Registry Editor’s address bar:
```
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
```
Right-click on the Windows folder and select New > Key. Name this key Windows Update.
Then right-click on this Windows Update key and select New > Key. Name it AU and save it.
Under this AU folder, go to the right-hand side, right-click on an empty location and select New > D Word (32-Bit value).
Name it NoAutoRebootWithLoggedOnUser and hit Enter to save it.
Now double-click on this file to open it. Type in 1 under the Value Data field and click OK to save it.
That’s it. Now reboot your PC and see if it fixes the Windows 11 automatically restarts issue.

FIX 6: Tweak Power Management Settings

If your PC is not in a charging state and is performing some resource-intensive tasks (that are asking for more than the allocated Virtual Memory), then the Power Management setting might force the system to undergo a restart. To overcome this, you should tweak this setting and instruct the Power Management not to perform this force reboot. Here’s how:

Open the Run window via Windows+R shortcut keys.
Then type in the below command and hit Enter. It shall launch the Power Options menu.
```
powercfg.cpl
```
Then click on Change plan settings next to your current plan.
After that, click on Change advanced power settings.
Now expand the Processor Power Management and then go to the Minimum processor state.
Make sure that the On Battery % is set to 5% or a lower value. If that is not the case, then do so right away.
After that, go to Link State Power Management (if your plan supports it) and change the On Battery status to OFF.
Once done, reboot your PC and then verify if Windows 11 automatically restarts issue has been fixed or not.

FIX 7: Disable Automatic Restart after System Failure

In its default state, Windows automatically undergoes a restart in case it detects any system failure. However, sometimes, it tends to get into a bootloop and isn’t able to access the OS. So to avoid that from happening, you should consider disabling its auto-restart feature once a system failure has occurred.

To do so, launch the Run dialog box via Windows+R shortcut keys.
Then type in the below keyword and hit Enter. This shall launch the System Properties menu.
```
sysdm.cpl
```
Go to the Advanced tab and click Settings under the Startup and Recovery section.
Finally, disable the Automatically Restart option under System Failure and click OK to save the changes.
That’s it, restart your PC and the underlying issue should now have been fixed.
