The issues persist even after a fresh installation of the OS and installing specific updates, indicating potential compatibility problems between the server hardware and certain updates from Microsoft. Users report encountering a Stop Code: IRQL NOT LESS OR EQUAL error originating from ntoskrnl.exe, which appears shortly after the login screen following an update installation.

Affected users have documented their experiences in various forums such as Reddit and Microsoft Q&A, underscoring the widespread nature of this issue. Despite efforts to mitigate problems through driver reinstallation or BIOS updates, no permanent solutions have been identified yet.
Issues with Windows Server 2025 Updates Leading to BSOD

The problem is characterized by the IRQL NOT LESS OR EQUAL stop code, originating from ntoskrnl.exe, and appears to affect both bare-metal installations and virtualized environments alike.
