Install Windows Update updates if they are not already downloaded and installs them afterwards. If the update is already downloaded it will only be installed.
Download Windows Update only downloads update packages but does not install them.
There are several settings to customize the download to your company needs.
The first setting is selecting the Source. The selection is between all Microsoft Updates (Windows + other Microsoft products), Group Policy Defaults (settings that additionally control how/when/where updates are applied), WSUS Updates (Updates controlled by your organization’s WSUS server, instead of directly from Microsoft.) and Windows Updates (Windows OS patches).
Severity, Classification and Products let’s you select tags, that will filter which updates will get installed or not. For example: Selecting Severity C (Critical) means only critical update packages will be downloaded. Additionally there is the option to add update lists.
Severity, Classification and Products allow you to pick something from a dropdown list, if filtering is required.
The Checkbox “Install only updates that are older than _ days” allows you to specify the days an update needs to be released to be installed, this can assure that only more stable updates get installed, since older updates are more likely to be fixed if they are unstable or have errors than when they first come out.
Denied and Allowed Update List allows you to add Deny and Allow lists. For more information regarding this, please read:
Additional WuInstall Options allow you to add commands for WuInstall like for example “/accept_all”.
Max Update Count allows you to specified how many updates can be installed at once.
