Web-based DSS are computerized systems that delivers decision support information or decision support tools to a manager or business analyst using a thin-client Web browser like Netscape Navigator or Internet Explorer.18.
There are two types of attestation modes you can use with the host guardian service: 1  Admin-trusted attestation: Allows hosts that you have designated as guarded hosts in Active Directory to decrypt and start shielded VMs. You designate hosts as guarded by placing them in a global security group that is created in AD.
That being said, Service Host(svchost.exe) is a generic service hosting container. Any number of required system services can be running in them, so I would not get rid of them. You can use Process Explorer to determine what services are running in the host container. My guess is it's Windows Update or BITS running.
