Hi
AppID Driver is a kernel device driver. In Windows 10 it is starting only if the user, an application or another service starts it.
If AppID Driver fails to start, the failure details are being recorded into Event Log.
Then Windows 10 will start up and notify the user that the AppID service has failed to start due to the error.
About restoring default startup configuration for APPID driver , we could follow these steps:
1.Run the Command Prompt as an administrator.
2.Copy the command below, paste it into the command window and press ENTER:
sc config AppID start= demand
3.Close the command window and restart the computer.
The AppID service is using the appid.sys file that is located in the %WinDir%\system32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
