Recently, I am using Android Studio to develop an app, but Android emulator can not work. It always displays the problem:
Android emulator is incompatible with Hyper-V
However I have turned off Hyper-V in program feature, but it is still a problem. I've been stuck on this for whole week.
Would anyone know how to fix this error?

If you're running Windows 10 in an enterprise environment, there's a chance the problem could be new "virtualization based security" features in Windows. If Device Guard or Credential Guard are enabled on your machine, that machine is using Hyper-V's hypervisor.
To check if that's the case, follow the instructions on this page or use the Device Guard and Credential Guard hardware readiness tool. Copied and pasted:
Typically, these features are enabled via Group Policy. If that's actually the root cause of the issue, you'll need to work within your organization to opt out of those policies.
One final note -- I do not recommend disabling Intel VT-x (as suggested by Will P), as I believe HAXM (the hypervisor used by the Android emulator) requires VT-x.
Full disclosure -- I work at Microsoft on the Hyper-V team.

It seems that a fairly recent "Fast Ring" build of Windows 10 has changed the default behavior of virtualization based security, so that it's enabled by default, and rather difficult to turn off (haven't been able to permanently disable it). Since I need Intel HAXM to run Android Studio, I am in a perpetual state of disabling VBS, restarting, then using the emulator and eventually I'll need to do it again. – jkane001 – 2018-03-15T01:42:09.860
More up to date instructions for disabling VBS can be found in this blog post: https://techcommunity.microsoft.com/t5/Windows-Insider-Program/Windows-Defender-System-Guard-Making-a-leap-forward-in-platform/td-p/167303

On an ASUS Z170M-PLUS motherboard and most likely other motherboards Intel® Virtualization Technology needs to be disabled via the bios to stop Hyper V services. 1. Reboot the machine. 2. Press delete or whatever key to enter the bios 3. Enter advanced mode and choose the advanced tab 4. Scroll down to Intel® Virtualization Technology and select disabled 5. Save and reboot the machine

Android emulator compatibility with Hyper-V is currently in preview. See this announcement for details: https://blogs.msdn.microsoft.com/visualstudio/2018/05/08/hyper-v-android-emulator-support/
