The error message “To be filled by OEM” appearing in Device Manager under the Bluetooth section (or in system information tools) indicates that the Windows Plug and Play manager cannot retrieve the correct hardware identifiers (VID/PID) from the Bluetooth adapter’s firmware or driver. Consequently, Windows loads a generic or incorrect driver, leading to Bluetooth malfunction (e.g., inability to pair devices, missing Bluetooth toggle, or code 28/31 errors).
This report provides a structured approach to identifying the actual Bluetooth hardware and installing the correct 64-bit driver for Windows 10. to be filled by oem bluetooth drivers windows 10 64 bit new

Conclusion for new Windows 10 64-bit: Always check for OEM drivers after initial OS installation. Generic drivers work for basic mice/keyboards, but fail for high-end audio, Bluetooth LE, or Intel Wireless-AC/AX chipsets. The VID (Vendor ID) and PID (Product ID) are the keys
The VID (Vendor ID) and PID (Product ID) are the keys. Here are common Bluetooth VID codes:
Solution: You likely have a combo Wi-Fi/Bluetooth card (e.g., Intel AC-7260, Realtek 8822BE). You must install both the Wi-Fi driver and the Bluetooth driver from the same package. Download the full combo driver suite from your motherboard vendor.
For future clean installations of Windows 10 64-bit, follow these best practices:
