We have official news from Microsoft, having paused the Windows 10 October 2018 Updates (Ver. 1809) for all users after issues of files being missing were raised. Hence, updates related to Windows 10 version 1809 will not be supported by Patch Manager Plus until the issue gets resolved.
If you've already created a configuration for the upgrade, you don't have to worry about missing any file, because we have moved all updates to the "Not supported" category.
Note: If you have manually downloaded the Windows 10 October 2018 update, please do not install it, wait until new media is available.
