• Is Windows 1511 Update unhiding the 1607 patch – again?

    I just got a report from AElMassry that Windows Update unhid the “Feature update to Windows 10, version 1607” again.

    Many people were caught unawares around January 20, when a similar unhiding took place. I talked about it then.

    Now it seems that, once again, 1511 users who have hidden the “Feature update to Windows 10, version 1607” are seeing the patch reappear. As I said two weeks ago:

    I can understand why having the 14393.447 build available could trigger hidden 1607 upgrades to become unhidden. After all, that’s what happens with earlier versions of Windows – when a new version of a patch rolls out, it’s usually automatically taken off the hidden list.

    But this is the first time I’ve seen it for Win10, and it seems disconcerting that folks who have intentionally hidden the 1607 upgrade are now getting it installed silently – on both Win10 Home and Win10 Pro machines.

    If you’re trying to block the upgrade to 1607 (Anniversary Update) by using wushowhide, watch out. Your system may be back in play.

    UPDATE: Fascinating explanation from the patchmanagement.org mailing list (which I’m not supposed to quote directly): It looks like this new version of the upgrade to 1607 is different from the one released in late January – the upgrade in late Jan was 3 GB, this one is 4 GB. That’s what would trigger another round of unhiding.

    Sure nice of Microsoft to warn us….
