Disable sound card using registry/Group Policy/batch processing

In the company, there is a department that reflects that employees often watch movies and listen to music. The sound card of all computers must be disabled. Check the registry and find that a sysaudio service exists in Windows, such:

The default start value is 3 (in manual mode). After you change the value to 4 (disabled), restart the computer, in the device management, the core sound device will have an exclamation point (for example), so that the sound card does not work, thus disabling the sound card.

Therefore, you can use the Group Policy to modify the registry, or use batch processing, and use SC, psservice, and other remote service management commands for remote operations. disable this service:

Net use // 192.168.1.2/User: computername/Administrator *

SC // 192.168.1.2 config sysaudio start = disabled

After the computer is restarted, the sound card cannot be used. Of course, you cannot grant the user administrator permissions. Otherwise, you can change the permissions.
