Your wireless headphones connect everywhere except the one machine you actually need them on, or your mouse stutters across the screen like the battery is dying when it is fully charged. Bluetooth problems on Windows 11 rarely announce a cause, so the smart move is to work through the simplest checks first and only touch drivers once the quick toggles fail. The fixes below are ordered from the safest, fastest options to the deeper driver work, and almost every one applies to Windows 10 too. Just keep in mind that Microsoft ended Windows 10 support on October 14, 2025, so the steps here center on Windows 11 with Windows 10 paths noted alongside.
Start With the Switch That Is Often Off
Before anything technical, confirm Bluetooth is actually turned on and that Airplane mode has not quietly disabled your radios. On Windows 11, select the Network, Sound, or Battery icons on the right side of the taskbar, then select the Bluetooth quick setting tile to turn it on. While you are there, check that the Airplane mode quick setting is turned off, since it shuts down Bluetooth along with Wi-Fi.
You can also flip the switch from the settings app at Start > Settings > Bluetooth & devices and set Bluetooth to On. On Windows 10, open the action center on the taskbar and select the Bluetooth tile, or go to Start > Settings > Devices and switch Bluetooth on; confirm Airplane mode is off under Start > Settings > Network & Internet.
Let the Built-In Troubleshooter Do the First Pass
Microsoft ships an automated Bluetooth troubleshooter that runs inside the Get Help app and can fix common issues without any manual digging. It is worth running early because it costs nothing and often catches a stuck radio or a misconfigured setting on its own.
To open it manually on Windows 11, follow this path:
- 1.Go to
Start > Settings > System > Troubleshoot > Other troubleshooters. - 2.Find Bluetooth in the list.
- 3.Next to Bluetooth, select Run and follow the prompts.
On Windows 10, the equivalent lives at Start > Settings > Update & Security > Troubleshoot. Let it finish, then test your device before moving on.
Rule Out the Device Itself
A surprising share of Bluetooth failures come from the accessory, not the PC. Make sure your Bluetooth device is turned on, charged or fitted with fresh batteries, and sitting within range of your computer rather than across the room or behind a wall.
The device also has to be in pairing or discoverable mode for Windows to see it, and the method differs by product, so check the device's manual for how to put it in pairing mode. If it still will not connect, turn Bluetooth off on your PC, wait a few seconds, then turn it back on to clear a stuck state.
Forget the Device and Pair It Fresh
When a device used to work and suddenly stops, a stale pairing is a common culprit. Removing it and pairing again rebuilds the connection cleanly. On Windows 11, do the following:
- 1.Open
Start > Settings > Bluetooth & devices > Devicesand find the device. - 2.Select More options (the three dots, shown as ...).
- 3.Choose Remove device, then select Yes to confirm.
- 4.Select Add device and choose your device from the list to re-pair.
On Windows 10, go to Start > Settings > Devices > Bluetooth & other devices, select the device, choose Remove device and confirm with Yes, then select Add Bluetooth or other device, pick Bluetooth, and select your device.
Give the Bluetooth Support Service a Restart
Windows runs a background service that handles Bluetooth, and restarting it can revive a connection without a full reboot. This is safe and quick, and it often clears problems where the radio is on but nothing will connect.
- 1.Press the Windows key + R to open the Run box.
- 2.Type
services.mscand click OK. - 3.Scroll down to Bluetooth Support Service.
- 4.Right-click it and select Restart.
Bluetooth Support Service is the name you will see in the list. Once it restarts, try your device again.
Stop Windows From Powering Down Your Adapter
If your Bluetooth keeps disconnecting at random, Windows may be cutting power to the adapter to save energy. You can turn that behavior off in Device Manager.
- 1.Open Device Manager and expand the Bluetooth section.
- 2.Right-click your Bluetooth adapter and choose Properties.
- 3.Select the Power Management tab.
- 4.Uncheck the box labeled "Allow the computer to turn off this device to save power."
Click OK to save. With that power-saving option disabled, the adapter stays awake and is far less likely to drop your connection mid-use.
Switch Off Energy Saver So It Stops Interfering
Battery-focused power modes can throttle Bluetooth to extend runtime, which sometimes breaks connections on laptops. On Windows 11, select the Battery icon in the taskbar and turn off Energy Saver mode so it does not interfere with Bluetooth.
On Windows 10, the same setting is called Battery Saver, and you turn it off the same way from the taskbar. If your problem only shows up when the laptop is unplugged or low on charge, this is very likely the cause.
Update the Bluetooth Driver
An outdated or buggy driver is one of the most common reasons Bluetooth misbehaves, and updating it is straightforward. Use Device Manager to pull the latest driver Windows can find.
- 1.Select Start, type Device Manager, and open it.
- 2.Expand the Bluetooth section.
- 3.Right-click your Bluetooth adapter and select Update driver.
- 4.Choose Search automatically for drivers and follow the prompts.
- 5.Restart your PC when it finishes.
You can also pull driver updates that arrive through Windows Update by going to Start > Settings > Windows Update > Check for updates and installing anything offered.
Roll the Driver Back If the Trouble Started Recently
The flip side of updating is that a recent driver can be the thing that broke Bluetooth. If your connection was fine until an update landed, rolling back to the previous driver is the targeted fix.
- 1.In Device Manager, expand the Bluetooth section.
- 2.Right-click your Bluetooth adapter and select Properties.
- 3.Open the Driver tab.
- 4.Select Roll Back Driver if it is available.
If the Roll Back Driver button is greyed out, Windows has no earlier version stored, so this option will not apply and you can move on to the next fix.
Reinstall the Driver by Uninstalling the Adapter
When updating and rolling back both come up short, reinstalling the driver from scratch can resolve a corrupted installation. Windows handles the reinstall for you automatically.
- 1.In Device Manager, expand the Bluetooth section.
- 2.Right-click your Bluetooth adapter and select Uninstall device.
- 3.Restart your PC.
After the restart, Windows reinstalls the Bluetooth driver on its own, giving you a clean copy. This is safe to do because the system rebuilds the driver during boot, but make sure you save any open work before you restart.
Install Windows Updates and Reboot
System updates frequently include Bluetooth fixes and driver improvements, and a plain restart clears many transient glitches on its own. Go to Start > Settings > Windows Update on Windows 11, or Start > Settings > Update & Security > Windows Update on Windows 10, select Check for updates, and install whatever is available.
Restart the PC once the updates are in place, even if Windows does not force it. If your Bluetooth was acting up because of an outdated system or a temporary fault, this final step often clears it for good.
Frequently Asked Questions
Why does my Bluetooth keep disconnecting on Windows 11?
The most common cause is Windows powering down the adapter to save energy. Open Device Manager, right-click your Bluetooth adapter, choose Properties, open the Power Management tab, and uncheck "Allow the computer to turn off this device to save power." Turning off Energy Saver mode from the Battery icon in the taskbar can help too.
How do I restart the Bluetooth service in Windows?
Press the Windows key + R, type services.msc, and click OK. Scroll to Bluetooth Support Service, right-click it, and select Restart. This refreshes the background service that manages Bluetooth without requiring a full system reboot.
My Bluetooth device will not pair. What should I check first?
Confirm the device is turned on, charged, within range, and in pairing or discoverable mode, since the steps to enter pairing mode vary by product and are listed in the device's manual. If it still will not pair, remove the device under Start > Settings > Bluetooth & devices > Devices and add it again from scratch.
Do these Bluetooth fixes work on Windows 10?
Yes. Nearly every fix here applies to both versions, with Windows 10 using slightly different menu paths such as Start > Settings > Devices for Bluetooth settings and Start > Settings > Update & Security for the troubleshooter and updates. Keep in mind Microsoft ended Windows 10 support on October 14, 2025.
What is the fastest fix to try first?
Make sure Bluetooth is actually on and Airplane mode is off using the quick settings on the taskbar, then run the built-in Bluetooth troubleshooter through the Get Help app. These two steps are the quickest and safest, and they resolve a large share of problems before you ever need to open Device Manager.
