Bluetooth pairing doesn't work on Windows 11

Hmm, that does seem unusual. I’m glad you were at least able to recover your mouse. I’m wondering if the issue might be with the headphones themselves, perhaps something like compatibility or if there’s something blocking the connection.

Since the mouse is also a Bluetooth device and connects fine, it suggests that Bluetooth is functioning at least partially.

Can you try performing a clean boot to check for any interference? Once you're in clean boot mode, try connecting the headphones.

If the problem goes away after a clean boot, it suggests a conflict with a third-party program. Start by enabling the programs you disabled one by one to identify the culprit.

I’ve been really scared this whole time. Let me tell you what I’ve done:

1. First, I restored the system to today’s date, but in the morning. My MX Ergo mouse appeared as already connected, but when I tried to connect my headphones, the issue persisted. That made me think the problem wasn’t resolved; I just went back to the point before I removed my mouse from my devices.
2. Because of that, I decided to restore the system to a few days earlier, specifically to January 14th, with a description labeled “Windows Modules Installer.” The reason I chose that date was because I remember there was a Windows update recently. I had also downloaded the Fortect application and performed some Scan & Repair operations on my system. Maybe I didn’t notice, but something from that might have affected the Bluetooth.
3. After restoring the system for the second time to this new date, I encountered a blue screen. I spent over an hour trying countless ways to fix it. Luckily, I was able to restore the system for the third time to today’s date, January 17th, in the morning.

So, I’m back to square one. The Bluetooth still won’t pair, but at least I’ve recovered my mouse.

Thanks for trying and for providing detailed information.

If none of the solutions work, a System Restore might be helpful. Keep in mind that this process will uninstall programs and drivers added since the restore point was established, but your files will be safe.

Press the Windows key + R to open the Run dialog box.

Type "rstrui.exe" and press Enter.

The System Restore window will open. Click "Next."

Select a restore point from a date when your computer was working correctly.

Click "Next," then "Finish."

Your computer will restart, and the system will be restored to the selected restore point.

I downloaded the driver from the link you provided, restarted, and it still doesn't work.

This issue just appeared today because I was previously troubleshooting a specific problem with my WH-1000XM4 headphones, which I detailed in this post.

Issues with WH-1000XM4 headphones compared to previous WH-910N - Microsoft Community

Before I started doing all of this, Bluetooth pairing was working correctly.

While trying to solve the issue, I do remember installing two drivers from the same page you shared. These were the Realtek HD Audio Driver and the Intel Bluetooth Driver. I also tried uninstalling and reinstalling the drivers in Device Manager.

I didn't touch anything in the Registry Editor because I know it's not advisable to make changes unless I'm absolutely sure of what I'm doing. Perhaps in my repeated attempts to manipulate the Bluetooth pairing with my headphones to fix the issue, Windows may have detected unusual or suspicious activity and is now blocking any Bluetooth pairing.

P.S.: When I realized my WH-1000XM4 headphones were no longer pairing, I removed my MX Ergo mouse from my Bluetooth devices to check if the issue was with my headphones or Windows. By doing that test, I confirmed there was a Bluetooth problem, but now I can't use the mouse either. 😢
Before doing this, the mouse was already connected and working without any issues.

Regarding the issue I mentioned in my first post, I could live with it and eventually get used to it. However, not being able to connect anything via Bluetooth to my computer has me much more worried. 😢
