Patch for MEM provides the ability to edit an individual update. It allows advanced users to modify an update’s metadata and to specify pre-installation and post-installation commands. You can edit an update before or after it is published.
WARNING! Editing an update can be risky and the edit tool is not for everyone. Only qualified administrators should attempt to modify an update.

There are two distinct types of modifications that can be made to an update:
•Modifications to the update’s metadata only: Changes made on any of the editor’s tabs except the Custom Install Script tab will modify only an update’s metadata. Modifying the metadata does not create a new installation file or a new update ID. After making your changes, if the update was previously published, a revision will be published to the WSUS server. If you have previously deployed the update, it is not necessary to alter the deployments after editing the metadata. The client machines that have not installed the update will receive the updated metadata.
•Modifications to the installation file: Any changes made on the Custom Install Script tab will result in a new update being generated that supersedes the update being edited. After the new update is published, you will need to deploy it in order for your clients to get the changes.
Updates can be edited from either the Updates or the Published Third-Party Updates workspace.
•Updates in the Updates list may or may not have already been published. When accessing an update from this location, the starting point for the update will always be the current catalog update. If an update has been edited with metadata changes only and published, you will be notified and those edits will not appear in the editor.
•When using the editor to open an update in the Published Third-Party Updates list, any previous edits you may have applied will be available.
•If you attempt to edit an update that has been superseded by another published updated (for example, one created by publishing the update with custom scripts), you will only be able to edit that update's metadata. The controls on the Custom Install Script tab will be disabled.
To access the update editor: Select the individual update that you want to modify and then either click the Edit button in the toolbar or right-click the update and choose Edit.
