The “To be filled by OEM” string originates from the SMBIOS (System Management BIOS) tables, specifically the “Manufacturer” field for system slots or devices. When the Bluetooth adapter is integrated into a Wi-Fi/Bluetooth combo card (e.g., Intel, Realtek, Qualcomm Atheros) and the motherboard BIOS does not properly populate the device’s vendor information, Windows substitutes the placeholder.
Technical flow:
The VID (Vendor ID) and PID (Product ID) are the keys. Here are common Bluetooth VID codes:
Download USBDeview (NirSoft) or Speccy (CCleaner). Run as administrator. Look for any entry labeled "Bluetooth Radio" or "Bluetooth Adapter." The manufacturer name will be displayed correctly, even if Windows driver shows "To Be Filled By OEM."
If correct OEM driver still not working:
A “new” system in this context means:
The phrase "To be filled by O.E.M." is a placeholder used by hardware manufacturers when the specific model or branding information has not yet been finalized or assigned to a system's BIOS or firmware. This typically occurs with custom-built PCs, white-label laptops, or unbranded motherboards where the "Original Equipment Manufacturer" (OEM) left these fields blank.
When this appears in your Bluetooth driver information on Windows 10 64-bit, it means Windows cannot identify the exact computer model to provide a tailored driver, forcing you to identify the hardware manually. How to Identify and Install the Correct Driver
Because your system isn't identifying itself by a brand name (like Dell or HP), you must find the specific Bluetooth chip 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. to be filled by oem bluetooth drivers windows 10 64 bit new
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.
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:
The phrase "To Be Filled By O.E.M." is a common placeholder used by motherboard and system manufacturers when they haven't customized the BIOS with a specific model name. This often happens with custom-built PCs or unbranded systems.
To find the correct Bluetooth drivers for Windows 10 (64-bit) for such a system, you must first identify the actual hardware inside. 1. Identify Your Bluetooth Hardware
Since your system model name is missing, use Device Manager to find the specific manufacturer of your Bluetooth chip (likely Intel, Realtek, or Broadcom): Right-click Start and select Device Manager. Expand the Bluetooth section.
Look for an entry like "Intel(R) Wireless Bluetooth" or "Realtek Bluetooth Adapter".
If you only see "Generic Bluetooth Radio," right-click it, select Properties, go to the Details tab, and select Hardware Ids from the dropdown. You can search for the "VID" (Vendor ID) and "PID" (Product ID) online to find the exact manufacturer. 2. Download and Install Drivers The “To be filled by OEM” string originates
Once you know your hardware manufacturer, download the official drivers directly:
Intel: Use the Intel® Driver & Support Assistant to automatically find the right 64-bit driver.
Realtek/Broadcom: These are often bundled with motherboard Wi-Fi drivers. If you know your motherboard model (e.g., ASUS, MSI, Gigabyte), go to their specific support page for that board.
Microsoft Generic: If specific drivers fail, Windows 10 includes a native Generic Bluetooth Radio Driver that provides basic functionality. 3. Quick Update via Windows If you prefer an automated method: Identify Your Bluetooth® Driver Version - Intel
The phrase "To Be Filled By O.E.M." is a placeholder used when the computer manufacturer did not enter specific model details into the BIOS. This usually happens with custom-built PCs or unbranded motherboards and does not impact performance, but it makes finding the right Bluetooth driver slightly more complex than just searching for a model name. 1. Identify Your Real Hardware
Since the "System Model" field is blank, you must find the actual manufacturer and model of your motherboard or the specific Bluetooth chip.
Check the Motherboard: Open System Information (search msinfo32 in the Start menu) and look for BaseBoard Manufacturer and BaseBoard Product. These will tell you the real model (e.g., MSI B850 Gaming Plus).
Find the Hardware ID: If you cannot find the motherboard name, you can identify the Bluetooth chip directly: Open Device Manager (right-click the Start button). Expand Bluetooth (or "Unknown devices" if missing).
Right-click your adapter (e.g., Generic Bluetooth Adapter) > Properties > Details tab.
Select Hardware Ids from the dropdown. Copy the top string (e.g., USB\VID_xxxx&PID_yyyy) and search for it online to find the exact manufacturer (Intel, Realtek, or Qualcomm). 2. Download the Correct 64-bit Driver
Once you know the hardware, visit the official support page for that specific brand to download the latest Windows 10 64-bit driver. Reboot
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?
