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)

https://docs.microsoft.com/en-us/windows/deployment/update/windows-update-logs 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. — hymced, Jan 06 '22 at 20:25

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).
