If you are part of the Windows Insider Program in the Fast ring and use Windows Mixed Reality (MR) you might want to hold off on updating to the preview build 17112.

The Windows 10 Insider Program is designed to offer users a chance to test out the latest builds of Windows 10 before they are released to the general public. There are two sections to the Insider Program which offer users different access to builds. The Slow ring is for those who want to test builds that are pretty much ready for release with the Fast ring being the front of the testing program. It is in this Fast ring that build 17112 has been released and with it the problem that Windows MR is not working has been encountered.

As to be expected in any testing program, problems may and will occur but for build 17112 it seems that Microsoft have pushed it out to the Fast ring in full knowledge of the Windows MR problem. Writing on the Windows Experience Blog, Dona Sarkar and Brandon LeBlanc write: “There are two issues impacting the usability of Windows Mixed Reality on this build. Windows Mixed Reality runs at a very low frame rate (8-10fps) that could result in some physical discomfort. And there are multiple crashes at startup that will cause Windows Mixed Reality to not work.”

If you are a Windows MR user then for now it would be best to hold off on updating to build 17112. To do this, users can pause the Insider Preview builds from installing by going to Settings > Update & Security > Windows Insider Program and pressing the “Stop Insider Preview builds” button and choosing “Pause updates for a bit”. Though the build includes a number of fixes, improvements and general changes to Windows 10 and remains stable enough for Microsoft to release, it is a shame that Windows MR has been rendered unable.

Elsewhere in the Windows 10 build 17112 users will experience issues with the Microsoft Store which may disappear or be completely broken. When trying to open an online-only file from OneDrive that hasn’t been downloaded to your PC before then there is a chance it will lead to a crash. Movies & TV crashes when navigating to the ‘Personal’ tab and a small number of users may encounter a reboot loop due to a failed installed when upgrading to the build.

Once again, Windows Insider Program users in the Fast ring will be the only ones with access to build 17112 at the moment and if you are wanting to avoid issues with Windows MR, make sure to avoid upgrading for now.
