New Windows Server updates cause DC boot loops, break Hyper-V. The most serious issue introduced by these #updates is that Windows Domain Controllers enter a boot loop, with servers getting into an endless cycle of #Windows starting and then rebooting after a few minutes. After installing Microsoft Updates, #Windows Resilient File System (ReFS) volumes are no longer accessible or are seen as RAW (unformatted) after installing the updates. In addition to the boot loops, Hyper-V no longer starts on the server. Microsoft released security updates to fix four different Hyper-V vulnerabilities yesterday (CVE-2022-21901, CVE-2022-21900, CVE-2022-21905, and CVE-2022-21847), which are likely causing this issue. #vuln #microsoft #windows #bugs #informatique
