Microsoft has pushed out an out-of-band update to address the restart loop that hit some Windows Server devices after its April update.
The fix will spare administrators the headache of forced server restarts after installing the April 2026 update. (A reminder that deploying any Microsoft update directly to production without thorough testing is, to put it charitably, a bold life choice.)
Microsoft said of the botched update, “After installing the April 2026 Windows security update (KB5082063) and rebooting, domain controllers (DCs) in environments with multiple domains in the forest that use Privileged Access Management (PAM), might experience LSASS crashes during startup.
“As a result, affected DCs may restart repeatedly, preventing authentication and directory services from functioning, and potentially rendering the domain unavailable.”
