Windows Server 2025 is now available - but Microsoft warns admins to watch out for three major bugs, including one that causes the dreaded blue screen of death

"Generally available today, Windows Server 2025 builds on our mission to deliver a secure and high-performance Windows Server platform tailored to meet customers' diverse needs," wrote Ian LeGrow, corporate vice president for Azure Edge and Platform.

"Customers operating fully in the cloud have inherent modern security advantages like automatic software updates and backup and recovery," LeGrow wrote. "Now we're bringing some of those capabilities to Windows Server 2025 for on-premises customers with a new hotpatching subscription service, enabled by Azure Arc."

On the security front, Microsoft has beefed up security in Active Directory, including new cryptographic support, and added new techniques for preventing a range of attacks against server message block (SMB), including hardened firewall defaults and protections against brute force, spoofing, and man in the middle attacks.
