sihclient.exe consumes CPU load with disabled WSUS Service

[EUCweb]

Anyone else seeing Trusted Installer kicking in, stealing CPU even when WSUS is set to Disabled on WS2016? And system is deploy from WIM already patched w latest CU. Very strange. Weak internet connection makes it even worse, so for now disabling WU/ TrustedInstaller (Class)

For BIS-F possible to enable scheduled task, called sih on private image boot and disable it with BIS-F if image is in shared mode and WSUS service is disabled

Actually I haven't disabled the sih task in my startup script (haven't seen that task running and consuming CPU yet), this is the task I regularly see consuming CPU on sealed images (if not disabled):
"\Microsoft\Windows\Servicing\StartComponentCleanup", also all .net tasks..

Services and scheduled Tasks are out of scope from BIS-F, check out #133

It can be done during startup with 99_PersBISF_StartUp.ps1
