• Confused by the second April Win10 1809 cumulative update and the second second update? You aren’t the only one.

    On May 1, Microsoft released the second cumulative update for the April cumulative update for Win10 1809. It’s KB 4501835, and it brings Win10 1809 up to build 17763.439. As I explained at the time in Computerworld:

    Oddly, in the Microsoft Catalog, the latest [KB 4501835] cumulative update is listed as:

    2019-05 Cumulative Update for Windows 10 Version 1809

    … whereas in the past, these 1809 laggards have been identified with the previous month. I would’ve expected “2019-04 Cumulative Update for Windows 10 Version 1809.” A foolish inconsistency.

    With me so far? It’s about to get crazy (and drive @PhotM nuts).

    On May 3 (today), Microsoft released its second second cumulative update for the April cumulative update for Win10 1809. (Say that ten times real fast.) It’s KB 4495667 and it brings Win10 1809 up to build 17763.475.

    Got that?

    Sooooo… what is this new update called? Why it’s the

    2019-05 Cumulative Update for Windows 10 Version 1809

    No, there’s no echo in here.

    Microsoft has apparently resolved, ahem, the discrepancy by renaming the former cumulative update

    2019-04 Cumulative Update for Windows 10 Version 1809

    without fanfare. If you check the Microsoft Catalog listings, you’ll see that it’s been renamed.

    @rpodric had a prescient tweet on this very subject earlier this morning, after the second cumulative update and before the second second cumulative update:

    and with that I think I’m ready for a drink. Thx @PhotM, @Kirsty
