    I have recently completed a clean install of Windows 10 Pro 21H2.

    On 1 July 2022, I downloaded and installed what Windows Update was offering me, which were a Defender virus definition update, MSRT, KB5014699 (2022-06 CU for Windows 10) and KB5008876 (2022-01 CU for .NET 3.5 and 4.8). I didn’t think anything more about the CU for .NET at the time; I just assumed that it was the latest CU available.

    However, today, I was notified that Windows Update is now offering me KB5013624 (2022-05 CU for .NET 3.5 and 4.8). Curious about this, I decided to query the Microsoft Update Catalog and discovered that KB5013887 (2022-06 CU for .NET 3.5 and 4.8) also exists.

    Does anyone have any idea why Windows Update is going through this long-winded process of getting my system up to date with .NET 3.5 and 4.8? Why could it not have offered me the 2022-06 CU in the first place? Is there any reason why I shouldn’t now hide the 2022-05 CU and wait for Windows Update to offer me the 2022-06 CU?

      June didn’t have any new security updates.  It always offers security first.

      June’s — KB5018337 Net Framewk 3.5-4.8 that Tony cites — is mentioned in varied – Some Got it, Some Still haven’t — Posts & July’s CU did NOT include it in mine (Receive Updates for Other MS Products is Chkd in Settings)… I see it in the Catalog, SO, should we manually install it ?   Many Thanks as always.

      First ensure that the tick box to get updates for other platforms is checked.

      I would opt to wait and get it as part of a cumulative security update in future months.

      I have a theory why KB5013887 (2022-06 CU for .NET 3.5 and 4.8) has not been offered to me by Windows Update, whereas KB5013624 (2022-05 CU for .NET 3.5 and 4.8) was offered.

      If you read the KB Microsoft Support article for KB5013887, it states that “There are no new security improvements in this release.”. Moreover, further on in the article, in the section entitled “How to get this update”, it states that the update is available though the Windows Update release channel, but is NOT available through the Windows Update for Business release channel.

      Now, using the Group Policy Editor, I have some settings configured in Windows Update for Business. So my assertion is that being configured for Windows Update for Business is determining which updates I receive. Would anyone like to confirm or deny that assertion?

      In the end, I downloaded KB5013887 from the Microsoft Update Catalog and installed it manually.
