Hi,
It may be the service itself or a missing dependency. Normally, this service
is not set to start automatically but rather manually (on demand). Run
services.msc from the start/search line and scroll down to the Diagnostic
Service Host. Double click it and check the settings to ensure it's set for
manual. On the Recovery tab, you may want to set the first failure option to
restart the service.
