Find Windows Update Given GUID from windowsupdate.log?

Question

When I look through the C:\windows\windowsupdate.log I see events like this :

Added update {19a3a735-8458-4b6c-baa8-eef88e4058cf}.201 to search result

How can I map a guid given in this way to an update? What is the significance of the .201? (or 200 or whatever, it varies)

Solution

If your update is finally selected for installation, you will find additional entries in the windowsupdate.log

Updates to download = 1
   Title = Some text description of the update
   UpdateId = {19a3a735-8458-4b6c-baa8-eef88e4058cf}.201

Otherwise, for a local WSUS server maybe an approach such as How to get a list of every WSUS update using PowerShell might be useful. For MS updates, the Microsoft Update Catalog shuld be queryable by id (I cannot test that from my OS).

docs.microsoft.com/en-us/windows/deployment/update/… says that for a given update revision (modified and republished on a service like Windows Update or WSUS), it keeps the same update ID (GUID) and get an incremented Revision number, which are often shown together as "{GUID}.revision.", but it also gets a unique Revision ID for that particular service. WindowsUpdate.log identifies them with the former identifier syntax.
