Enabling Microsoft Update via PowerShell or Command Line?

Many Microsoft products, such as Microsoft Office, can be updated using built-in Windows Update features. However, it may not be enabled by default on all of your systems. Your existing RMM may fall short of properly enabling it, and therefore will not see updates for Microsoft products, leaving them unpatched and exposed to vulnerabilities. The following script enables it, and you can run this script using your RMM.

Note that if you utilize Action1 for patch management, it does not require this script, because Action1 does not rely on Windows Update Agent’s service manager catalog. It will simply detect all Microsoft product updates without any extra configuration steps.
