Microsoft has patched multiple bugs that cause setup, improvement, and Blue Screen of Death (BSOD) issues on Windows Server 2022 devices with high core counts.
Frustratingly, the symptoms of Windows Server 2025 setup or upgrade attempts often manifest as prolonged and unresponsive installation procedures, accompanied by server boot times that can stretch up to three hours or even exceed it in some cases. Customers experiencing issues may also encounter blue screens upon startup, reboot, or application launch attempts.
Despite Redmond’s explanation that these issues don’t manifest persistently on affected devices.
To detect whether your Windows Server 2025 system has been impacted, launch the Task Manager by simultaneously pressing the Ctrl, Shift, and Esc keys. Then, navigate to the Performance tab and check if it displays more than 256 logical processors.
“This issue was resolved by Windows updates released on November 12, 2024, and subsequent iterations,” the company stated today. “We strongly recommend installing the latest safety update on your equipment, which includes critical improvements and issue fixes, including this specific enhancement.”
Microsoft provides an alternative solution for those unable to immediately install the KB5046617 November Patch Tuesday cumulative update, recommending that administrators limit the number of logical processors on affected devices to fewer than 256 as a temporary workaround.
To adjust the performance settings, proceed with modifying the number of logical processors available, as outlined below.
- Reboot your system and navigate to the Unified Extensible Firmware Interface (UEFI) settings menu. Access and explore firmware menus, whose configurations may vary depending on the manufacturer.
- Can I dynamically adjust the processor configuration to optimize system performance and power consumption by modifying the number of cores per socket?
- Establish a range for cores per socket at a price point ensuring the aggregate number of logical processors remains 256 or fewer, considering the total count is derived by multiplying the number of sockets by cores per socket and subsequently multiplying that product by logical processors per core.
- Restart the server.
“The adjustment of logical processor configurations may vary depending on the specific firmware installed on your device,”
Microsoft is investigating and working to resolve an issue with Windows Server 2025 affecting iSCSI environments, resulting in “boot machine inaccessible” errors on impacted devices?
