I am experiencing the same issue with a latest-generation HP EliteBook.
I have already tested the following scenarios:
- Windows 11 25H2 and 26H2, both with and without interrupting the OOBE.
- When using the preinstalled version of Windows Pro, the system runs normally and the Wi-Fi adapter driver works as expected. However, the issue occurs when using Windows Enterprise.
The problem appears after the system has been running for a certain amount of time. Windows then becomes unstable and sluggish, with symptoms such as a black screen, the taskbar disappearing, and overall poor system performance.
Approximately one month ago, Windows 11 25H2 was working without any issues.
