I just installed the Windows 10 anniversary update and now I can't start my Android emulators.
Android Studio shows the following message.
Android Emulator is incompatible with Hyper-V
bcdedit /set hypervisorlaunchtype off
emulator -avd Nexus_5_API_23
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: Please disable Hyper-V before using the Android Emulator. Start a command prompt as Administrator, run 'bcdedit /set hypervisorlaunchtype off', reboot.
The problem in my case is that I had Credential Guard and Virtualization Based Security.
I disabled the mentioned Windows 10 features using Device Guard and Credential Guard hardware readiness tool.
Unzip the tool, in a Powershell command go to the folder where you unzipped the tool and type:
After rebooting I was able to reinstall HAXM and start my emulators.
