Bluetooth Turns Off After Restart in Windows 11? 10 Proven Fixes (2026 Guide)

Introduction

If your Bluetooth keeps turning off every time you restart your Windows 11 PC, you’re not alone.

This issue has become increasingly common—especially after recent Windows updates—where Bluetooth either:

• Turns off automatically after reboot
• Fails to reconnect to paired devices
• Completely disappears from settings

In this guide, you’ll learn exact causes + step-by-step fixes that actually work in 2026.

Why Bluetooth Turns Off After Restart

This issue is usually caused by one (or more) of the following:

Power management settings and drivers are among the most common causes.

Fix 1: Disable Power Saving for Bluetooth (Most Effective)

This is the #1 fix.

2. Expand Bluetooth
3. Right-click your Bluetooth adapter → Properties
4. Go to Power Management tab
5. Uncheck:
   • ✔ Allow the computer to turn off this device to save power
6. Click OK

Since Windows may disable Bluetooth to save power, this fix often resolves the issue.

Fix 2: Restart Bluetooth Services

Sometimes Bluetooth fails because its background service didn’t start properly.

Steps:

1. Press Windows + R
2. Type services.msc
3. Find:
   • Bluetooth Support Service

5. Set Startup Type → Automatic
