win10, iis10 can not start, w3svc service failed to start

IIS is stoped, can't start.

When I checked services, the dependencies of w3svc are all running, but can't start w3svc.

Tried reinstall IIS (turn off iis feature => restart => turn on iis feature), not working. :(

Tried this : IIS w3svc error

find solution here, the cause of problem is win10 insider 14942 issue:

Insiders doing web development may find themselves their local intranet server unreachable, as service host separation will leave the IIS World Wide Web Publishing Service (W3Svc) unable to start successfully. To fix this issue:

Run the following from an admin cmd line (or edit the registry accordingly):
    REG ADD HKLM\SYSTEM\CurrentControlSet\Services\W3SVC /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
    REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WAS /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
Reboot the system, so that the W3Svc and WAS services share a service host process.
