Error 0x81000036 when Using Windows Backup

Backups always save the day. Think of the spare tire in your trunk or the extra pair of earbuds you’ve got in your bag ‘just in case’. 

Yet out of all the things we can think of right now, the data on your hard drive probably needs a backup more than anything. Whether it’s the images of your most recent vacation, an office assignment, or a semester’s worth of homework, you do not want to lose any of it. 

Luckily, Windows comes with a built-in backup feature that users can use to create or restore backups of their files in case of data corruption, hard drive failure, or malware. But life is not a bed of roses, is it?

Recently several users reported that their screens are displaying error 0x81000036 when they attempt to restore Windows to a previous working version. This error can occur due to a number of reasons, including a conflict with Windows Sandbox and Hyper-V.

If you are facing a similar issue, you are in the right place because in this guide, we are going to walk you through the relevant troubleshooting steps in detail. 

Let’s get started. 

1. Disable Windows Sandbox.

The Sandbox is a lightweight environment that is around 100 MB in size where you can run unauthorized software without affecting your system. 

There are times when the Windows Sandbox functionality conflicts with the Windows Restore feature, resulting in errors like the error code 0x81000036. 

Several users managed to fix the issue at hand by temporarily disabling Windows Sandbox, which is why we encourage you to give it a shot. 

Here is what you need to do:

  1. Press Windows + R keys simultaneously to open a Run dialogue box. 
  2. In the text field of the dialogue box, type ‘appwiz.cpl’ and press Enter. This will launch the Programs and Features window. 
  1. In the Programs and Features window, click on Turn Windows features on or off.
  1. In the next window, locate Windows Sandbox and uncheck the box against it. 
  1. Click Yes in the User Account Prompt (UAC) to proceed. 

If the issue was caused by Windows Sandbox, disabling it temporarily will resolve the issue. If you face the error 0x81000036 when using Windows Backup again, proceed to the next method below. 

2. Disable Hyper-V.

Another common reason behind the Troubleshoot error 0x81000036 when using Windows Backup is the conflict between Hyper-V and Windows Restore feature.

Hyper-V lets the users share hardware resources across virtual machines. Advanced users use it to create one or multiple virtual machines if they want to install and run different operating systems on a single Windows 10 PC. 

However, just like the Sandbox, it can sometimes conflict with Windows processes and cause issues. 

If Method 1 did not work for you, here is how you can disable Hyper-V to fix the error code 0x81000036:

  1. Press Windows + R keys simultaneously to open a Run dialogue box. 
  2. In the text field of the dialogue box, type ‘appwiz.cpl’ and press Enter. This will launch the Programs and Features window. 
  3. In the Programs and Features window, click on Turn Windows features on or off.
  4. Now locate Hyper-V and uncheck the box associated with it. 
  1. Click on Yes in the User Account Prompt and check if the issue is resolved. 

In case Hyper-V was the culprit, disabling it will fix the issue under consideration. If you manage to resolve the issue, you can enable Hyper-V again by following the steps mentioned above. 

3. Try Using CleanMyPC.
