Win 10 V2004 --> Windows Sandbox --> Create System Image Failure
I updated Windows 10 to Version 2004 3 days ago. After the update, I turned on the Windows Sandbox feature (Control Plane --> Turn Windows Features On or Off --> Checked marked Windows Sandbox. The sandbox feature works pretty well and is a feature I should have been using and will likely use in the future.
Next, as I generally do after an update is working (appears to be working), I wanted to Create A System Image using the Control Panel option Back and Restore (Windows 7). I've done this many, many times with no problem. But this time I got a "Windows could not find back up device on this computer. The following might explain why this problem occurred: 0x81000036" error. What? Why? The external drive is connected and viewable in File Explorer. Where to begin? Do I have to uninstall Version 2004?
It turns out one reason for this error (0x81000036) was the activation of Windows Sandbox feature. After turning this feature off; I could create system image normally. Why? Don't know. Frustrate? Somewhat. No...very frustrated.
I thought others might be interested.
Regards and hope your upgrade goes smoothly.
