It is undesirable for a Power Studio playout machine to stop playout because Window Update kicks in. Maybe it even wants to restart the PC.
This article describes how to disable Windows Update using the build in Policy Editor.
These steps require that you are running Windows 10 Pro or above.
To block the upgrade via Group Policy, use the following steps:
Hit Windows key + R to launch the Run dialog box.
Type gpedit.msc and click OK.
Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage end user experience

Take note that, while it is essential for a playout machine to not "randomly" start the Windows Update process and reboot, installing updates is a nescesary part of computer maintenance. It is recommended to manually run Windows Update on a regular basis.
While doing this, it is recommended to have a different audio source on air, as Windows Update might disrupt the computers network or audio drivers or reboot the computer.
