Is your Bluetooth turning off or resetting every time you restart your Windows 11 PC?

This is a common issue faced by many users — Bluetooth headphones, mice, or other devices stop working after reboot, or the settings don’t get saved.

In this guide, we’ll walk you through the most common causes and step-by-step solutions to keep Bluetooth working normally.

目次

Cause 1: Fast Startup is Enabled

Fast Startup is a Windows feature that allows your PC to boot faster. However, it sometimes interferes with saving the state of Bluetooth devices.

How to Disable Fast Startup:

  1. Search for “Power Options” in the Start Menu and open it
  2. Click “Choose what the power buttons do”
  3. Click “Change settings that are currently unavailable”
  4. Uncheck “Turn on fast startup (recommended)”
  5. Click “Save changes”

Disabling Fast Startup has little to no impact on boot speed, but it may prevent your Bluetooth settings from resetting.

Cause 2: Outdated or Corrupt Bluetooth Driver

Bluetooth drivers act as the bridge between Windows and your Bluetooth hardware. Outdated or broken drivers can lead to connection issues or settings not being saved.

How to Update the Driver:

  1. Right-click the Start button and open “Device Manager”
  2. Expand the “Bluetooth” section
  3. Right-click your Bluetooth adapter and choose “Update driver”
  4. Select “Search automatically for drivers”
  5. Restart your PC after updating

If Bluetooth doesn’t show up, try “View” → “Show hidden devices” in Device Manager.

Cause 3: System File Corruption

If important Windows configuration files are damaged, Bluetooth services may not behave correctly or fail to save settings.

Fix It Using SFC and DISM:

Open “Terminal (Admin)” from the Start menu and run the following commands one by one:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Then restart your PC.

Cause 4: Registry Settings Disabling Bluetooth

Some Windows registry entries can disable Bluetooth or prevent it from starting automatically after a reboot.

⚠️ This step is for advanced users. Be careful when editing the registry.

How to Check the Registry:

  1. Press Win + R, type regedit, and press Enter
  2. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BTHPORT\Parameters
  3. If you see a key named AutoEnableBluetooth, set its value to 1

Back up the registry first or consult someone knowledgeable if unsure.

Cause 5: Power Management Settings Disabling Bluetooth

Some laptops automatically turn off Bluetooth to save battery, especially during sleep or low-power modes.

How to Fix This:

  1. Go to “Device Manager” → expand “Bluetooth” → right-click your adapter → “Properties”
  2. Click the “Power Management” tab
  3. Uncheck “Allow the computer to turn off this device to save power”

This prevents Windows from disabling your Bluetooth adapter when idle or during reboot.

Bonus Tip: Using a USB Bluetooth Adapter

If your built-in Bluetooth continues to fail, a low-cost USB Bluetooth dongle can be a reliable workaround.

Summary

Bluetooth issues after restarting Windows 11 are often caused by power settings, Fast Startup, outdated drivers, or registry conflicts.

Try each method above step by step. In most cases, one of these will solve the problem and make your Bluetooth devices work reliably again.

If not, you may consider replacing the adapter or seeking professional PC support.
