Microsoft Acknowledges Windows 10 Preview Build 18999 Shutdown Problem

Microsoft has confirmed a shutdown problem in Windows 10 Preview Build 18999 and moved it under Known Issues.


Over the last few days, users on the Windows Insider Program has been testing Windows 10 preview Build 18999. However, those users are describing a problem with the update. Specifically, the newest Insider build is causing PC shutdown issues.

Many users say when they select to shut down the PC, the machine is not really shutting down. Instead the screen goes black while the PC continues to run in the background.

has quickly acknowledged the problem and updated its official blog post for Windows 10 preview Build 18999. The shut down problem is now listed under known issues and Microsoft has offered the following:

We are “investigating reports that some devices are getting stuck during shutdown or restart.” The company has not explained what is causing the problem. Any affected users will need to roll back to an older build to avoid the problem.

It is worth noting, while users are pointing to this problem, it's not the same situation as recent Windows problems. Microsoft's recent patches for Windows have been causing problems, such as a Start menu problem the company is currently dealing with.

These have all been problematic updates for the full Windows 10 release branch. Of course, in these situations Microsoft should start to get its game together to ensure patches are more stable.

However, the Windows 10 preview Build 18999 problem is arguably part and parcel of the Insider Program Fast Ring. This is where Microsoft builds are unstable and problems are meant to be discovered. As such, this is exactly the right time to find this issue.

Build 18999

Windows 10 preview Build 18999 arrived last week. The biggest addition was the ability for the Your Phone app to take and make calls from a connected Android device.

According to Microsoft's blog, the feature allows the following:

  • Answer incoming phone calls on your PC.
  • Initiate phone calls from your PC using the in-app dialer or contact list.
  • Decline incoming phone calls on your PC with custom text or send directly to your phone's voicemail.
  • Access your recent call history on your PC. Clicking on a specific call will auto populate the number within the dialer screen.
  • Seamlessly transfer calls between your PC and phone.
