Microsoft earlier this week released its latest Patch Tuesday update, the release is for the month of April 2026. On Windows 11 under KB5083769 and KB5082052, the new update brings a major Remote Desktop-related change, among other things. There have been bugs too, like a BitLocker recovery bug as well as another one where Windows Server systems keep restarting.
Alongside the Patch Tuesday updates, Microsoft also released new dynamic updates for Windows 11 and 10. For those who may not know, dynamic updates bring improvements to the Windows Recovery process in the form of Windows Recovery Environment (WinRE) updates, which are also called Safe OS updates. The dynamic updates also affect the Setup file binaries in the form of Setup updates.
These Dynamic Update packages are meant to be applied to existing Windows images prior to their deployment. Dynamic Updates also help preserve Language Pack (LP) and Features on Demand (FODs) content during the upgrade process. VBScript, for example, is currently an FOD on Windows 11 24H2.
This time, only recovery updates were released for Windows 11 and 10. The company writes:
