Exceptionally, Microsoft delivers a loose patch outside the traditional cycle to fix urgent problems within Windows and Windows Server.
Every second Tuesday of the month is traditionally Patch Tuesday at Microsoft and all services are updated. The intention is to fix things and make them more secure, but sometimes something breaks. In this case, the VPN service within Windows and a lot of critical issues within Windows Server. For example, administrators reported that their domain controllers went into an endless bootloop, ReFS volumes became inaccessible and appeared as RAW file systems, and Hyper-V would no longer boot.
The new updates will be actively offered through the official Windows Update channel on each platform. Those who would like to download the update manually can go here:
