If you are trying to update to a Windows Insider Preview build, you might encounter an update compatibility hold and receive the message, "This PC can't upgrade to Windows 10. Your PC isn't supported yet on this version of Windows 10. No action is needed. Winodws Update will offer this version of Windows 10 automatically once the issue has been resolved."
An issue has been found with certain Windows 10 devices and some Windows Insider Preview builds. After installing an affected Windows Insider Preview build on an affected Windows 10 device, you might experience Windows not responding, a stop error, unexpected restart or shutdown.
To safeguard your update experience, we have applied a compatibility hold on these devices from installing or being offered some Windows Insider Preview builds.
We are working on a resolution and will provide an update in an upcoming release.
Note We recommend that you do not attempt to manually update using the Update now button or the Media Creation Tool until this issue has been resolved.
