How can I fix error 0x81000019 on Windows 10?

2. Enter services.msc in the Run accessory’s text box, and click the OK option.
3. Double-click Volume Shadow Copy to open the window in the snapshot directly below.

8. Press the Start button there if the service is stopped.
9. Click OK to exit.

2. Free up storage space

The 0x81000019 error can often arise when there’s insufficient storage space available on the destination or source drive. So, make sure you have sufficient space on the drive you’re trying to back up Windows 10 to.

Furthermore, you’ll also need to have a good amount of space available on the source drive (about 40 percent free space). So, you might need to free up space if your hard drive is very full.

There are various methods to free up storage. Software will usually take up the most space, so uninstalling superfluous apps is one of the best methods.

In addition, you can also free up quite a lot of space by deleting junk files with system maintenance utilities.

3. Expand the system reserved partition

Some users might need to expand their reserved system partition space to more than 500 megabytes to fix the x81000019 error. You can do that with the freeware MiniTool Partition Wizard software.

Click Free Download on its download page to get the installer for that software. That linked page also includes guidelines for how you can expand the system reserved partition with MiniTool Partition Wizard Free 11.

4. Erase System Restore points

Error 0x81000019 could be due to outdated system restore points if the error message says The specified object could not be found.

1. To fix that, open Run.
2. Enter Control Panel in the Open box, and click OK.
3. Click System and Security on the menu shown directly below.
   
4. Click System.
5. Click System protection on the left to open the window shown directly below.
   
6. Then press the Configure button.
7. Press the Delete button shown directly below.

5. Disable or uninstall third-party antivirus software

Third-party antivirus software, such as Avast, McAfee, and Comodo, might be interfering with the Windows Backup.

Try disabling your third-party antivirus utility by right-clicking its system tray icon and selecting a disable option on its context menu, like the one in the snapshot directly below.

Select to disable it until you restart Windows to give yourself time to carry out the backup. Some users might need to completely uninstall their third-party antivirus software to fix error 0x81000019.

The above resolutions might fix error 0x81000019, but they’re not entirely guaranteed for all users. If the resolutions above aren’t enough, try running a system file scan with the sfc /scannow command.

As a final resort, a repair install of Windows will probably do the trick.
