Dear Tushar Gupta,
Welcome to the Microsoft Community
I understand you're experiencing issues with connecting Bluetooth devices to your Windows 10 32-bit system, and that you're unable to find a compatible Bluetooth driver for your system.
Please note that Bluetooth drivers are typically provided by the hardware manufacturer, not by Microsoft. This means that Windows only provides basic drivers, and any updates or specific drivers are usually released directly by the manufacturer. In your case, it seems the driver available on Intel's website may not support your version of Windows.
To help you further, could you please provide the model number of your motherboard or network card module? With this information, I can assist you in finding a compatible Bluetooth driver that should work with your Windows 10 32-bit system.
Looking forward to hearing from you!
Best Regards,
Martin | Microsoft Community Support Specialist
