In the Job Center you can create update lists where updates can be combined in a list. These lists can then be used as Allow or Deny lists by adding the previously created update list to either the Denied Updates List or Allowed Updates List when creating a job for Wuinstall.
A deny list selects the updates that you do not want to install for various reasons. With this method, all updates are installed except for those on the deny list. In doing so, you can for example create a job that installs only updates that are 30 days old or older, except for the updates on the deny list. Then you create a second job that installs all updates, even new ones, except for the updates on the deny list on test devices. With this method you can test on the test devices which updates work and which don’t, and you have 30 days to put them on the deny list.
With the Allow list, only updates are installed that are on the update list. In doing so, each update must be individually reviewed and packed onto the list. In the Update Center, for example, you can view updates, and consider and inform yourself on the Internet, which updates you want to have and then put them on the list. This method has the advantage that only updates that you really want are installed on the devices.
