This is not the first time that Patch Tuesday security updates have caused one or more inconveniences to users. But that of January 2022 concentrated various disturbances which prompted Microsoft to urgently publish patches. Reports from administrators have reported Windows domain controllers experiencing spurious reboots. Additionally, Hyper-V no longer started on Windows servers and Windows Resilient File System (ReFS) volumes were no longer accessible.

Additionally, Windows 10 users and administrators have also reported issues with L2TP VPN connections after installing recent Windows 10 and Windows 11 cumulative updates. “.

An update package

Microsoft has therefore hastened to respond to the increasingly growing criticism and has therefore just published urgently (out of band), “these updates which resolve problems related to VPN connectivity, restarting Windows domain controllers Server, failure to launch VMs and inability to mount removable media formatted in ReFS”. All fixes are available for download from the Microsoft Update Catalog and some of these fixes can be installed directly through Windows Update as optional updates. In the latter case, patching will be done manually.
