Unable To Set Application Identity Service to Start Automatically
<p>On Windows 10 Enterprise laptops I found the AppIDSvc was stopped and its Startup Type was set to Manual (Trigger start).  When I attempted to change the Startup Type to Automatic via the GUI, it produced the error "Access is denied" even though services.msc from run from an elevated cmd prompt.  </p>

<p>The only way to work around this was to edit the registry and changing  Start=2 at HKLM\SYSTEM\CurrentControlSet\Services\AppIDSvc.</p>

<p>I was able to start the service manually. Also I have modified the registry permission to "Full Control". I tried to reinstall Windows from ISO but the problem persists. Unfortunately Microsoft doesn't reply to this problem clearly on <a href="https://social.technet.microsoft.com/Forums/en-US/d4f085f6-6b5f-4970-8651-17f417dec6ca/action?threadDisplayName=unable-to-start-application-identity-service-for-applocker-on-windows-10-enterprise&amp;forum=win10itprosecurity" rel="nofollow">MSDN</a> and <a href="http://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_repair/cannot-change-application-identity-service-to/bd037720-27a6-4eef-b8f0-94e7ad57729f?auth=1" rel="nofollow">Support Forum</a>.</p>
