When Windows updating goes bad — the case of the problematic patch
Every month, Windows users and administrators receive updates from Microsoft on Patch Tuesday (or Wednesday, depending on where you're located). And each month, most users all apply the same updates.
But should we?
Case in point: KB5012170, a patch released on Aug. 9 that either causes no issues — or triggers Bitlocker recover key requests or won’t install at all, demanding that you go find a firmware update. This patch, called the Security update for Secure Boot DBX, applies to nearly all supported Windows releases. Specifically, it affects Windows Server 2012; Windows 8.1 and Windows Server 2012 R2; Windows 10, version 1507; Windows 10, version 1607 and Windows Server 2016; Windows 10, version 1809 and Windows Server 2019; Windows 10, versions 20H2, 21H1, and 21H2; Windows Server 2022; Windows 11, version 21H2 (original release), and Azure Stack HCI, version 1809, all the way to Azure Stack Data Box, version 1809 (ASDB).
