If Device Manager shows Bluetooth entries named "To Be Filled By OEM" or your Bluetooth is missing/not functioning after an update, that usually means Windows doesn’t have correct vendor information or the proper driver/firmware is installed. This post shows safe, practical steps to identify the problem and restore working Bluetooth on a Windows 10 64-bit PC.
USB\VID_0A12&PID_0001&REV_8891The VID (Vendor ID) and PID (Product ID) are the keys. Here are common Bluetooth VID codes:
VID_8087 → IntelVID_0A12 → Cambridge Silicon Radio (CSR)VID_413C → Dell (often Broadcom or Realtek)VID_0B05 → ASUSTek (usually Realtek)VID_04CA → Lite-On (Broadcom or Qualcomm)VID_8086 → Intel CorporationAfter a clean Windows installation, the problem can reappear. Use these strategies:

Navigating the "To Be Filled By O.E.M." Bluetooth Driver Mystery
If you've checked your Windows 10 "System Information" and seen "To Be Filled By O.E.M."
instead of a manufacturer name, you aren't alone. This common placeholder can make finding the right Bluetooth drivers for your 64-bit system feel like a guessing game. What Does "To Be Filled By O.E.M." Actually Mean?
This phrase is a generic placeholder in your computer's BIOS. It appears when: Custom Builds:
You or a shop built the PC using an off-the-shelf motherboard. Missing Data:
The manufacturer (Original Equipment Manufacturer) didn't encode specific model or serial details into the firmware. Retail Windows: to be filled by oem bluetooth drivers windows 10 64 bit new
You installed a retail version of Windows on a machine that doesn't have OEM-specific branding. Crucially, this does not affect your PC's performance. It is simply a missing text field in the registry. How to Find Your Real Bluetooth Driver
Since "To Be Filled By O.E.M." isn't a brand, you can't search for its drivers. Instead, you need to identify the actual hardware hidden behind that label. 1. Identify Your Motherboard (The Hardware Source)
Most Bluetooth chips are integrated into the motherboard. To find the real manufacturer:
How to Fix "To Be Filled by O.E.M." Bluetooth Driver Issues on Windows 10 (64-bit)
When you see the message "To be filled by O.E.M." in your Windows 10 system information, it usually means the manufacturer (Original Equipment Manufacturer) did not encode specific identification details into the system's BIOS or firmware. While this is common for custom-built PCs, it can make finding the right Bluetooth drivers a challenge because you don't have a clear "System Model" to search for on a support website.
Below is a guide to identifying your hardware and installing the correct 64-bit drivers for your "new" or newly updated system. 1. Why You See "To Be Filled by O.E.M."
This placeholder text is standard for retail motherboards or custom builds where the builder (the OEM) is expected to fill in the branding. It has no negative effect on your computer's performance, but it does hide the model name you need for driver downloads. 2. How to Identify Your Bluetooth Hardware
Since Windows isn't telling you the model, you have to look deeper into the hardware IDs or the "BaseBoard" (motherboard) information. Method A: Check the BaseBoard Model
Even if the "System Model" is blank, the BaseBoard Product often contains the actual model number. Press Win + R, type msinfo32, and hit Enter. Look for BaseBoard Manufacturer and BaseBoard Product. How to Fix "To Be Filled By OEM"
For example, if it says "Micro-Star International" and "B850 GAMING PLUS WIFI," you know to look for MSI drivers. Method B: Use Hardware IDs (Most Reliable)
If you can't find the motherboard model, identify the Bluetooth chip itself:
"To be filled by O.E.M." is a common placeholder text found in the Windows registry and BIOS that indicates your computer's manufacturer (Original Equipment Manufacturer) did not enter specific model or serial number information into the system's firmware. This is particularly common in custom-built PCs, unbranded systems, or motherboards purchased directly for self-assembly. Why You See This for Bluetooth Drivers
When you search for Bluetooth drivers on Windows 10 (64-bit) and see this label, it typically means the system is identifying the hardware through a generic placeholder because the specific SKU or model name was never "filled in" at the factory. This generally does not affect your computer's performance, but it can make finding the correct driver more difficult since you lack a specific model name to search for. How to Install the Correct Driver
Since the "To be filled by O.E.M." label won't point you to a specific download, follow these steps to find the actual driver your hardware needs:
Identify the Chipset Manufacturer: Instead of looking for the "OEM" model, look for the actual manufacturer of the Bluetooth module (often Intel, Realtek, or MediaTek) in Device Manager.
Use Windows Update: Go to Settings > Update & Security > Windows Update and click Check for updates. Windows will often find the correct driver automatically based on the hardware ID, even if the label is generic.
Manual Download: If you know you have an Intel-based system, you can download the latest 64-bit Bluetooth drivers directly from the Intel Driver Support Page.
Motherboard Manufacturer Site: If you built the PC yourself, visit the support page for your motherboard model (e.g., MSI, ASUS, Gigabyte) to find the specific Bluetooth drivers for that board. How To Install Bluetooth Drivers On Windows 11 / 10 Right-click the Start button and select Device Manager
If your system information displays "To Be Filled By O.E.M."
, it simply means the manufacturer of your custom-built or unbranded PC did not enter specific model details into the BIOS. This placeholder does not affect your computer's performance, but it does make finding drivers manually a bit trickier. Microsoft Learn Windows 10 64-bit
system, follow these steps to identify and install the correct Bluetooth drivers. 1. Identify Your Bluetooth Hardware
Since the system model is hidden, you must find the specific brand of your Bluetooth radio (e.g., Intel, Realtek, or Qualcomm). Use Device Manager : Right-click the button and select Device Manager Locate the Adapter : Expand the

: If the device is listed as "Unknown Device," right-click it > Properties tab > select Hardware Ids
from the dropdown. You can search for the "VEN" (Vendor) and "DEV" (Device) codes online to find the exact manufacturer. 2. Download Drivers from the Manufacturer
Once you know the hardware brand, download the latest 64-bit driver directly from that company's support site rather than third-party portals.
The “To be filled by OEM” issue in Windows 10 64-bit is a driver identification failure, not a hardware fault in most cases. By correctly identifying the Bluetooth chip (via Wi-Fi combo, USB tools, or physical check) and installing the matching 64-bit driver from the chip vendor or PC OEM, full Bluetooth functionality is restored. If the problem persists after following this report, consider replacing the Bluetooth module or using an external USB adapter.
