Towards the end of last week, Microsoft released a new “Windows 10 build 14279” for Surface Book, Surface Pro 3 and Surface Pro 4 2-in-1 tablets specific to Windows Insider fast ring users. For those uninitiated, fast ring users get the latest OS builds sooner than the general public. However, the flip side is that such builds may not be stable and they are prone to bugs.

Latest Windows 10 Build Problems

As it turns out, the latest build 14279 causes the following devices to freeze: Surface Book, Surface Pro 3 and Surface Pro 4. Upon installing the build, owners of the aforesaid devices will not be able to use the Type Cover keyboard, trackpad and touchscreen.

In any case, readers should note that Microsoft is aware of the ongoing issue and the company is currently investigating it. A permanent fix will be rolled out in the near future.

However, as of now, Microsoft has suggested a workaround to fix the problem temporarily. The tech giant is requesting the Surface users to hold the power button down in order to force the tablet to hard-reboot.

Official Windows blog post says: “We’re investigating an issue in which some Surface Pro 3, Surface Pro 4, and Surface Book devices experience a freeze or hang and all input such as keyboard/trackpad and touch do not work. The workaround is to hold down the power button to force the device to hard-reboot.”

Windows 10 Mobile Cumulative Build

On a related note, WinBeta says, the Windows 10 Mobile cumulative update, tied to the build number 10586.164, is now being tested by Microsoft. Apart from the fix for the swipe keyboard malfunction introduced in the build 10586.122, the latest cumulative build is reported to bring continuous improvement to the migration process from Windows Phone 8.1 to Windows 10 Mobile. Lastly, the official Windows 10 Mobile roll out will start sometime this month.
