DISM /Online /Cleanup-Image /RestoreHealth
After DISM finishes, run sfc /scannow again and restart Windows.
17. Check BIOS or UEFI Bluetooth Settings
If Bluetooth is completely missing from Windows and Device Manager does not detect the adapter, the hardware may be disabled at the firmware level.
Restart your computer and enter the BIOS or UEFI setup. The key varies by manufacturer and may be F2, F10, F12, Delete, or Esc.
Look for settings related to:
- Wireless devices
- Bluetooth
- WLAN
- Internal Bluetooth
- Wireless LAN
If Bluetooth or wireless hardware is disabled, enable it, save your changes, and boot back into Windows.
Important: BIOS/UEFI menus are different for every manufacturer. Avoid changing unrelated settings if you are not familiar with BIOS configuration.
18. Check Whether Your PC Actually Has Bluetooth
Not every desktop computer includes built-in Bluetooth.
If you are using a custom-built desktop, open Device Manager and check whether a Bluetooth adapter is present. Some motherboards include Wi-Fi and Bluetooth together, while others do not.
If your computer does not have Bluetooth hardware, Windows cannot enable Bluetooth through software alone.
In that case, you can add Bluetooth using a compatible USB Bluetooth adapter or an internal expansion card.
