Good point. I’ve seen people report grey screens and login issues online, but there doesn’t seem to be enough evidence yet to say the update is causing a widespread problem.
Before blaming the update, I’d check for driver updates too. Sometimes a Windows update exposes an existing driver issue, making it look like the update is the problem.
One of my laptops started taking much longer to boot after the update. I’m not sure if KB5094126 is the cause, but the timing seems suspicious.
That’s usually how Windows update issues work. A bug can affect specific hardware, drivers, or software configurations while most users never notice anything wrong.
I installed it a few days ago and haven’t had any problems. Everything seems normal on my desktop, so it might only be affecting certain systems.
Has anyone else had issues after installing the Windows 11 KB5094126 update? I came across reports from users experiencing grey screens, login problems, and other weird issues after updating.

I wasn’t so lucky. My old work laptop asked for the recovery key after a motherboard replacement, and I couldn’t find the key anywhere.
Fortunately, yes. I found it in my Microsoft account and regained access within a few minutes.
that’s a common situation. Many newer Windows devices enable BitLocker automatically during setup. Were you able to locate the recovery key in your Microsoft account?
This happened to me after a BIOS update on my Dell laptop. After rebooting, Windows suddenly asked for a BitLocker recovery key. I honestly didn’t remember enabling BitLocker in the first place.
Many Windows users have reported being prompted for a BitLocker recovery key after a Windows update, BIOS update, or hardware change. In some cases, users suddenly lose access to their files and are unsure how to regain access to their drives.
I had a similar issue after a sudden power outage. The drive was detected but showed an “Access Denied” error whenever I tried to open it.
Yes, everything was there once the drive letter was reassigned.
Hopefully Microsoft looks into it soon. For now, it seems like some users are having issues while others are completely unaffected, so it may depend on the individual PC setup.
