[Solved] Need Help with Windows Sandbox Initialization Error (0x80070005)

[ValentinasS]

Hi everyone,

I'm encountering an issue with Windows Sandbox on my system. When I try to start it, I get the following error message:

---

Windows Sandbox failed to initialize.

Error 0x80070005. Access is denied.

Would you like to submit feedback about this issue?

---

I've attached a screenshot of the error message for reference.

Has anyone faced a similar issue or does anyone have any suggestions on how to fix this? I've tried the following solutions so far without success:

• Restarting the computer
• Running Windows Update to ensure all patches are installed
• Checking Windows features to ensure Sandbox is enabled (tried also to reenable)

Any help or guidance would be greatly appreciated!

Thanks in advance!

Read the release notes of the Windows Insider build you are running.

Under "Known Issues"

I know the error code could be different, but its still the same. It's a known issue. It still does not work in the new build released today.

1.Ensure Windows Features are Enabled:

Make sure that Windows Sandbox is enabled in your system.
Go to Control Panel > Programs > Turn Windows features on or off.
Check if Windows Sandbox is checked. If not, enable it and restart your PC.

2.Update Windows:

Ensure your Windows installation is up to date. Go to Settings > Update & Security > Windows Update and check for updates. Install any available updates.

3.Running Windows Sandbox with Administrative Privileges:

Right-click on the Windows Sandbox icon and select Run as administrator. This might resolve permission-related issues.

4.Check Group Policy Settings:

Press Win + R, type gpedit.msc to open the Local Group Policy Editor.
Navigate to Computer Configuration > Administrative Templates > System.
Find settings related to user rights and permissions. Ensure that there aren't any policies in place that could deny access to Windows Sandbox.

Ensure that your system meets the requirements for running Windows Sandbox, including Windows 10 Pro, Enterprise, or Education version 1903 or later.

In addition, virtualization is enabled in your system's BIOS/UEFI settings.
