Realtek Bluetooth drivers are essential for enabling Bluetooth functionality on many laptops and desktops, particularly those using Realtek Bluetooth radios. These drivers can be downloaded from the official support websites of your device manufacturer, such as Dell or HP, by entering your device’s model number or service tag to locate the correct driver. For example, Dell provides specific Realtek Bluetooth drivers for models like the Vostro 5460, supporting Windows 7 and Windows 8.
The most recent Realtek Bluetooth drivers available as of early 2025 include versions such as 18.4032.2510.901 WHQL for the 8922AE chip, released on October 15, 2025. Other updated drivers include versions for 8852CE (released October 11, 2025), 8852BE (July 2, 2025), and 8851BE (September 19, 2025). A Bluetooth LE Audio Driver version 2.0.11.0 WHQL is also available for certain models, released on March 18, 2025.
If the driver is missing or malfunctioning, you can manually reinstall it using Device Manager. Open Device Manager, locate the Bluetooth section, expand it, right-click on the Realtek device, and select "Update Driver". Choose "Browse my computer for driver software" and point to the folder where the downloaded driver files are located. Alternatively, you can use Windows Update to check for optional updates that may include the latest Realtek Bluetooth drivers.
In some cases, older Realtek Bluetooth drivers (prior to version 1.5.1012) can prevent Windows 10 updates, such as the November 2019 Update (version 1909), due to compatibility issues. Microsoft has applied a safeguard hold on such systems until the driver is updated to a compatible version. If automatic updates fail, manually downloading and installing the correct driver from the manufacturer’s site is recommended.
For users experiencing connectivity issues, such as choppy audio or failure to reconnect devices, troubleshooting steps include restarting Bluetooth services via the Services app, resetting Bluetooth settings, and re-pairing devices. If problems persist, a hardware issue with the Bluetooth adapter may be present, requiring repair or replacement.

Realtek Bluetooth Adapter Keeps Disconnecting After Driver Update?
Ever since my Dad got me a gaming rig I've been having trouble with the Bluetooth drivers. Anytime I want to connect anything like wireless headphones, it simply will not connect, or when I try to use a controller there is this weird thing where horrible input lag will kick in out of nowhere and mess up my controller for 15 seconds or so. This isn't exclusive to games but also emulators, I know it's not the controllers because I've use different controllers from different platforms and each works fine on their respected platform and even my old potato laptop from 2014. All of this information combined leads me to believe it's the drivers.
According to the device manager my PC uses Realtek Bluetooth. Though I went to the site and downloaded updated drivers, but nothing has changed.
PS: Both my old laptop and My gaming rig uses Windows 10. Also, I've only been using Windows 10 frequently since 2019 and have been PC gaming for just as much time, I only got this new PC a few months ago. Forgive my ignorance and or misinterpretation of certain things.
Thank you for your response.
I have tried the steps you rcommended and I continue to have
the same issue.
- Device Manager - Uninstalled Realtek Bluetooth 5.0 Adapter
- Restarted PC
- All drivers are up to date, yet the issue remains that the
only device affected is the wireless headphone (Cowin E-7),
I lose the sound, although it appears in Bluetooth devices,
and is replaced by "speakers." - I have to reload the minidisk for the Realtel Bluetooth 5.0
Adapter to load the Realtek drivers back on and re-install Realtek
Bluetooth. After this is complete the wireles headphones
work well.
Guess I shall ignore any updates, since headphones work well
without updates.
Should you have any other resolution, please let me know.
Thanks again for getting back.

I’ve been struggling with my Realtek Bluetooth adapter randomly disconnecting after a driver update. Has anyone found a specific version that works reliably?
Where did you get your driver update from? If I cannot get one directly from the manufacturer of the adapter, (and it doesn’t look like Realtek has Bluetooth drivers on their website,) I would download it from the PC manufacturer’s site.
What driver version are you currently using?
Can you downgrade to the previous version if it was working?
Ran into this problem also, complaining about old Realtek BT drivers but none installed.
First check for non-present devices in Device Manager by enabling hidden items under View/Show hidden devices. If you still don't see your bluetooth device listed, you may have an orphaned driver file like I did.
Check your C:\Windows\System32\drivers folder for the file RtkBtfilter.sys.
An old Realtek bluetooth driver, not being used but detected by the updater
Deleted the file and update was able to continue.
There was nothing logged in the CompatData().xml files as suggested to check here:

(I guess because it wasn't installed nor was there any inf file for it)
It seems that your Realtek Bluetooth driver is too outdated,
as described in the Microsoft article
Updating to a new version of Windows 10 on devices with some driver versions for Realtek Bluetooth radios.
A workaround is found in the article Microsoft Removes Windows 10 1909 Realtek Driver Update Block :
- Download these two Realtek Bluetooth radio drivers: Driver 1 and Driver 2
- Using File Explorer, double-click both and extract their contents into the same folder, but in two different sub-folders
- Start Device Manager
- Find and expand "Bluetooth"
- Right-click the Realtek device and select Update Driver
- Select "Browse my computer for driver software" and position to the above folder
- It should find the drivers and install them
- Select Close.
Windows 10 version 1909 may now agree to install (if it finds the hardware acceptable).
