Microsoft Confirms Windows Sandbox Problem in Windows 10 Version 1903

Some builds of Windows 10 May 2019 Update are causing the Windows Sandbox feature to not start up. Microsoft says a fix is coming next month.


Last week, began the rollout of the May 2019 Update. As with all new feature upgrades, Windows 10 version 1903 introduced plenty of interesting new tools. Among them was the Windows Sandbox features, which allows the safe running of programs and apps. However, it seems this handy new tool isn't working for a subset of users.

Sandbox Mode is one of the standout features of Windows 10 May 2019 Update. As the title suggests, the Windows Sandbox allows users to run programs within a disposable virtual machine. This VM never interacts with the OS, allowing potentially dangerous services to be run securely. Microsoft says Sandbox is limited to Windows 10 Pro and Enterprise users.

Sadly, some users on Reddit and Microsoft own support tool say they Windows Sandbox is not working.

Microsoft has published a support document that confirms there is a problem with the Sandbox. The company says the tool may not start on some Windows 10 version 1903 Build 18362.113 releases. To denote the problem, Microsoft has given it the error code 0x80070002.

“Windows Sandbox failed to start. Error 0x80070002. The system cannot find the file specified,” the error reads.

“Windows Sandbox may fail to start with “ERROR_FILE_NOT_FOUND (0x80070002)” on devices in which the operating system is changed during the update process when installing Windows 10, version 1903,” Microsoft says.


A fix is in the works as I write this, but Microsoft says it will not be available to roll out until late in June. Sadly, there is no know workaround for the problem. Windows 10 1903 early adopters may have to manage without the benefits of Windows Sandbox for the next month.
