Microsoft has acknowledged bugs in Windows Server 2025 affecting systems with more than 256 logical processors, leading to installation failures, prolonged restarts, and Blue Screen of Death (BSOD) errors. Symptoms include unresponsive installation processes, server restarts taking over three hours, and blue screens during application launches. Not all devices are affected, and users can check their system's logical processor count via the Windows Task Manager. Microsoft is working on a fix for these issues, expected in a future update, and recommends limiting logical processors to 256 or fewer as a temporary solution. Additional problems include language discrepancies during installation and boot issues in iSCSI environments. Windows Server 2025, introduced in January to the Windows Insider program, includes features like next-gen Active Directory and hotpatching capabilities, and is now generally available with a 180-day trial.
