Windows 10 build 10049 has a Hyper-V bug and here's a temporary solution

Hyper-V, for those that did not know, is a virtualization platform on Windows. Hyper-V is a native hypervisor that can create virtual machines on x86 and x64 systems, typically enabled by app developers who are testing apps via Visual Studio. For those of you who have Windows 10 build 10049 installed, there is a bug affecting Hyper-V, as detailed by Microsoft in an official blog post today.

“The bug stops us from being able to correctly register one of our system drivers if you choose to install Hyper-V.  It should be noted that if you already have Hyper-V enabled, and then upgrade to 10049 – everything works fine.  It is only if you install build 10049 and then enable Hyper-V that you will hit this issue,” Microsoft says.

This issue only occurs if you had Hyper-V disabled as you upgraded to build 10049. However, those of you who had Hyper-V enabled prior to upgrading to build 10049 will not encounter the bug. While Microsoft works to fix this issue, there is a temporary solution. All you have to do is install an earlier build of Windows 10, enable Hyper-V, then upgrade to build 10049. Not an easy solution but it will have to do until the company releases a fix, likely in time for the slow ring rollout of build 10049.
