Solving the ‘Windows Sandbox No Hypervisor Found’ Error

Are you encountering the ‘Windows Sandbox No Hypervisor Found’ error? Worry not, as we have put together a comprehensive guide that will help you tackle this issue head-on. Updated to reflect the latest advancements and solutions, this guide will offer practical steps for resolving this common problem.

Understanding and Fixing the ‘Windows Sandbox No Hypervisor Found’ Error

Windows Sandbox is an innovative feature provided by Microsoft, catering primarily to enterprise and professional users who need to execute untrusted applications safely. It creates an isolated environment apart from your main system, essentially starting a fresh instance of a Windows environment each time it’s launched. This sandbox ensures that any application you install stays confined and does not impact your main operating system. Once you close the Windows Sandbox, the application together with all its files and state is securely deleted.

Despite its usefulness, some users may encounter an error stating that no hypervisor was found, which can disrupt the functionality of Windows Sandbox. This guide will walk you through enabling this feature and fixing the common errors associated with it.

Ensuring CPU Virtualization is Enabled

Checking for CPU virtualization is a vital first step. You can do this by opening the Task Manager, simply right-click the Start button and select Task Manager. In the window that appears, click the Performance tab to view your virtualization status. If it shows as disabled, you’ll need to enable it within your system’s BIOS or UEFI settings.

You should also verify if Hyper-V is enabled on your computer and check for support for Second-Level Address Translation (SLAT) on your CPU.

Activating Necessary Windows Features

Windows Sandbox relies on certain operating system features to function properly. Follow these steps:

  • Search for ‘Windows Features’ in the start menu search box.
  • Select ‘Turn Windows features on or off’ from the results to access the menu.
  • Look for ‘Virtual Machine Platform’ and ‘Windows Hypervisor Platform’ in the list, and make sure to check their boxes.
  • Click ‘OK’ to save your changes and apply the new settings.

Once you have completed these steps, reboot your system to check if the ‘Hypervisor not found’ error has been resolved.

Configuring Hypervisor Automatic Startup

Another solution to consider is to set the hypervisor to automatically run on system startup. This involves adding an entry to the Boot Configuration Data (BCD). Here’s how:

  • Open the Run dialog by pressing Windows Key + R.
  • Type ‘cmd’ and then use CTRL + SHIFT + ENTER to open an elevated command prompt.
  • Type in the command BCDEDIT /Set {current} hypervisorlaunchtype auto and press Enter.

After restarting, verify that the hypervisor launch type status is ‘Auto’. This indicates a successful configuration for the hypervisor to run at the start-up. Perform another restart to see if the issue has been tackled.
