Fix: Windows Backup Error 0x81000036

So, now you may ask what are the possible reasons behind such an issue to some of the unfortunate Windows 10 users. Well, it seems that the conflict with the Windows sandbox as well as the conflict with Hyper-V can basically trigger the backup error in most scenarios. If you also feel the same, make sure to go through all the possible workarounds mentioned below.

1. Try Disabling Windows Sandbox

Windows Sandbox allows users to safely run programs separately. So, that the full system remains ‘sandboxed’. You may experience issues with the system data backup process with this in some cases.

So, make sure to temporarily turn off the sandbox feature on your Windows computer before taking backup and restore. To do so:

• Click on the Start menu or Windows Search bar > Type Control Panel and click on it from the search result.
• Now, click on Programs > Select Programs and Features.
• Head over to Turn Windows features on or off from the left pane.
• A new small window will open on the screen > You’ll see a list of native Windows features.
• Make sure to scroll down the list and click on the Windows Sandbox checkbox to disable it or uncheck it.
• Once turned off or unchecked, click on OK to save changes.
• You may have to confirm the action by clicking on Yes and wait for the Sandbox environment to disable.
• Now, go back to the Windows Backup utility and retrying the restoration process to check whether the problem has been fixed or not.

2. Turn Off Hyper-V

In other ways, sometimes it can also possible that there is a conflict between the default Windows Backup Restore process and the Hyper-V service. By default, Hyper-V comes enabled on Windows 10.

Therefore, some unfortunate Windows 10 users may start receiving backup and restore-related errors. Luckily, if you’re facing the same problem, then you can temporarily disable the Hyper-V service on your Windows 10 computer before trying to restore a backup.

• Click on the Start menu or Windows Search bar > Type Control Panel and click on it from the search result.
• Now, click on Programs > Select Programs and Features.
• Head over to Turn Windows features on or off from the left pane.
• A new small window will open on the screen > You’ll see a list of native Windows features.

• Make sure to scroll down the list and click on the Hyper-V checkbox to disable it or uncheck it. [On some computers, you may see ‘Windows Hypervisor Platform’]
• Next, click on OK to save changes. [If it prompts to confirm the action, click on Yes]

• Once the Windows Hyper-V functionality gets disabled, just restart your computer to change effects immediately.
• Finally, you can try attempting to restore the previously created restore point using the default Windows Backup and Restore option.
• Enjoy!
