Configuring Standalone WSUS Mode
You can publish third-party updates to standalone WSUS without SCCM. To allow updates to appear directly in WSUS, follow the instructions in this article.
Standalone WSUS mode is only required when you are not using Configuration Manager for software updates and are only using WSUS. When enabled, published third-party updates will appear directly in the WSUS console.
Enable Standalone WSUS Mode
To enable standalone WSUS mode, go to the Updates tab and select Options. In the WSUS options window check the box Make updates appear in the WSUS console. This option isn’t needed if using Configuration Manager.
If your WSUS database is using a Windows Internal Database (WID), the database connection options will be read-only.
When using a SQL Server for the WSUS database, you will need to choose either to connect to the database using the SYSTEM account or define a user name and password using SQL authentication.
Verify Third-Party Updates Appear in the WSUS Console
Any updates published after this setting was enabled should appear directly in the WSUS console.
You can now deploy the third-party updates just like a Microsoft update directly from the WSUS console.
If updates were published before this setting was enabled, they would not appear in the WSUS console automatically.
For updates published before WSUS Standalone mode was enabled, use the Modify Published Updates Wizard to make those updates appear in the WSUS console.
