Windows 10 Insider Preview build 14267 is out and ‘known issues’ include Hyper-V upgrades

The Windows team just announced the availability of Windows 10 Insider Preview build 14267 to Fast Ring Insiders. As with each new build now surfacing it is apparent that the Windows team is still in fix-it mode, patching holes and squashing bugs.

However, even fixing items in Windows 10 comes at a cost and sometimes breaks previously existing functionality for a time being. Fortunately, as the Windows team gets a collectively better handle on Windows 10 development, the list of broken items or “known issues” has gradually shrunk over time.

As for build 14267, here are the known issues:

If you’re using Hyper-V and upgrade to this build with more than one vswitch or have multiple virtual networking adapters (including legacy), you may lose networking connectivity after upgrade. To get network connectivity back, there are two workarounds available:

  • Remove all the virtual network adapters connected to the vswitch, delete the vswitch and recreate it, then reconnect their virtual NIC to the new vswitch.
  • Admin command prompt, do “netcfg -d” will wipe-out all the vswitch settings so that you can start from scratch.

Thankfully, even the known issues in this latest build have workarounds. For Fast Ring Insiders, head over to your Update Settings and apply the latest Windows 10 Insider preview today.

Let us know your experience with build 14267 thus far.

Happy downloading, Insiders!
