If you are searching for How to restart bluetooth service windows, your Bluetooth may have suddenly stopped connecting, your headphones may keep disconnecting, or Windows may show Bluetooth as enabled while your devices refuse to work.
Before reinstalling drivers or making risky system changes, try the overlooked fix: restart Windows Bluetooth Support Service.
Microsoft specifically recommends restarting Bluetooth Support Service when Bluetooth connections repeatedly disconnect. The process takes only a few moments through services.msc and does not require you to reboot the entire PC first.
This guide explains How to restart bluetooth service windows using the standard Services method, along with PowerShell and Command Prompt alternatives, the difference between Bluetooth Support Service and Bluetooth User Support Service, and what to do if restarting the service does not fix the problem.
Quick Answer
For the quickest answer to how to restart Bluetooth service Windows, use the Services console:
- Press Windows + R.
- Type
services.msc. - Press Enter.
- Find Bluetooth Support Service.
- Right-click it.
- Select Restart.
- Wait a few seconds.
- Test your Bluetooth device again.
Microsoft documents this services.msc procedure for Bluetooth connections that repeatedly disconnect.
If Restart is unavailable because the service is stopped, select Start instead.
The service is commonly identified as bthserv. Advanced users can also control Windows services through PowerShell or sc.exe.
Key Takeaways
- The main service to restart for this fix is Bluetooth Support Service.
- The easiest method is
Windows + R → services.msc → Bluetooth Support Service → Restart. - Restarting the service can help with temporary connection and disconnection problems.
- Bluetooth User Support Service is a separate per-user Windows service.
- PowerShell provides another way to restart the service.
- Restarting Bluetooth service cannot repair a missing or corrupted driver.
- If Bluetooth failed after an update, driver rollback may be more appropriate than another update.
- Power-saving settings can contribute to repeated Bluetooth disconnections.
- Bluetooth that is connected but produces no sound may actually have an audio-output problem.
- If Windows cannot detect the Bluetooth adapter, restarting the service alone is unlikely to solve the issue.
What Is the Bluetooth Service in Windows?
Bluetooth on Windows involves both hardware and software.
The Bluetooth adapter is the hardware component that communicates with Bluetooth accessories. Windows services help the operating system manage Bluetooth discovery, pairing, and related functionality.
The service most relevant to this guide is:
Bluetooth Support Service
Its service name is:
bthserv
Microsoft describes Bluetooth Support Service as supporting discovery and association of remote Bluetooth devices. Stopping or disabling it can prevent Bluetooth devices from operating properly or being discovered.
That distinction matters.
Restarting a Bluetooth service refreshes part of the Windows software environment. It does not physically restart, repair, or replace the Bluetooth adapter itself.
Bluetooth Support Service vs Bluetooth User Support Service
When you open services.msc, you may find more than one Windows service containing the word Bluetooth.
Do not assume they are interchangeable.
| Service | What It Does |
|---|---|
| Bluetooth Support Service | Supports Bluetooth discovery and association of devices |
| Bluetooth User Support Service | Supports Bluetooth functionality relevant to an individual Windows user session |
Microsoft documents Bluetooth User Support Service with the service name BluetoothUserService and a default startup type of Manual.
You may also see a user-specific instance such as:
BluetoothUserService_XXXXX
The characters after the underscore can differ between systems or user sessions.
If you are following a guide on How to restart bluetooth service windows, start with Bluetooth Support Service rather than changing every Bluetooth-related service you see.
Do Not Change Every Bluetooth Service
- Seeing Manual beside Bluetooth User Support Service does not automatically mean something is wrong.
- Microsoft documents
BluetoothUserServiceas a per-user service with Manual as its default startup type. - Therefore, do not force every Bluetooth-related Windows service to Automatic simply because another tutorial recommends it.
How to Restart Bluetooth Service Windows
The easiest method uses Windows Services.
Microsoft recommends this method as one of its solutions for Bluetooth devices that repeatedly disconnect.
Method 1: Restart Bluetooth Service With Services.msc
Step 1: Open Run
Press:
Windows + R
Step 2: Open Windows Services
Type:
services.msc
Press Enter or select OK.
The Windows Services management console will open.
Step 3: Find Bluetooth Support Service
Scroll down until you find:
Bluetooth Support Service
Do not randomly restart every Bluetooth-related service in the list.
Step 4: Restart the Service
Right-click Bluetooth Support Service.
Select:
Restart
Windows will stop the service and start it again.
Step 5: Test Bluetooth
After the restart:
- turn the affected Bluetooth accessory off and back on
- wait several seconds
- open Settings > Bluetooth & devices
- try reconnecting the device
If Bluetooth begins working normally, you can stop troubleshooting there.
This is the simplest method for most people who want to know how to restart Bluetooth service Windows without rebooting their entire computer.
Method 2: Restart Bluetooth Service With PowerShell
Advanced users can restart Windows services with PowerShell.
Open PowerShell as Administrator and run:
Restart-Service -Name bthserv
To check the service state afterward, run:
Get-Service -Name bthserv
Restart-Service stops and restarts a specified Windows service, while Get-Service lets you check its current state.
If the service is already stopped, PowerShell may attempt to start it.
Method 3: Restart Bluetooth Service From Command Prompt
You can also control the service through an elevated Command Prompt.
Open Command Prompt as Administrator.
Stop the service:
sc.exe stop bthserv
Then start it again:
sc.exe start bthserv
To query its status:
sc.exe query bthserv
The sc.exe query command displays status information about a specified Windows service.
Which Method Is Best?
| Method | Difficulty | Best For |
|---|---|---|
services.msc |
Easy | Most Windows users |
| PowerShell | Medium | Advanced users |
sc.exe |
Medium | Command-line troubleshooting |
For most readers searching how to restart Bluetooth service Windows, services.msc is the best starting point.
How to Restart Bluetooth Service Windows After an Update

If Bluetooth stopped working immediately after Windows Update or a Bluetooth driver update, restarting Bluetooth Support Service is still worth trying first:
Windows + R → services.msc → Bluetooth Support Service → Restart
However, an update-related problem may actually involve the driver.
If Bluetooth worked before a recent Windows or driver update, rolling back the Bluetooth driver may resolve the problem.
A sensible sequence is:
Restart Bluetooth service → test Bluetooth → inspect the driver → roll back the driver if the problem started after an update
This avoids reinstalling software unnecessarily while still addressing update-related failures.
Why Restarting Bluetooth Support Service Can Work
Bluetooth can fail even when the adapter itself is still functioning.
Repeated Bluetooth disconnections can be related to factors such as:
- temporary system glitches
- power-saving settings
- outdated drivers
Restarting Bluetooth Support Service can refresh the Windows service responsible for part of Bluetooth device discovery and communication.
A restart is especially worth testing when Bluetooth:
- suddenly stops responding
- repeatedly disconnects
- worked normally earlier
- stops reconnecting after sleep
- refuses to reconnect to an already paired accessory
- appears enabled but behaves inconsistently
However, restarting bthserv is not a universal repair.
If Windows cannot detect the Bluetooth adapter or the driver is damaged, the underlying issue exists at another layer.
Restart Bluetooth Service vs Turn Bluetooth Off and On
These fixes sound similar, but they refresh different parts of the Bluetooth environment.
| Action | What It Refreshes | Best Used For |
|---|---|---|
| Turn Bluetooth off/on | Bluetooth connection state | Minor pairing glitches |
| Restart Bluetooth Support Service | Windows Bluetooth service | Service-related failures |
| Update or restart adapter driver | Hardware-driver communication | Driver problems |
| Restart PC | Wider Windows environment | Persistent system issues |
If you are learning How to restart bluetooth service windows, it helps to understand that restarting Bluetooth Support Service is different from simply switching Bluetooth off and back on.
Turning Bluetooth off, waiting about 10 seconds, and turning it back on can help with basic connection or pairing problems.
A useful troubleshooting order is:
Toggle Bluetooth → restart Bluetooth Support Service → test again
What If Bluetooth Support Service Is Stopped?
If Bluetooth Support Service is already stopped, you may not see an active Restart option.
Instead:
- Right-click Bluetooth Support Service.
- Select Start.
- Wait for the service state to change.
- Test Bluetooth again.
If Windows refuses to start the service, do not immediately edit the Registry.
Check the Bluetooth adapter and driver first.
What If Restart Bluetooth Service Is Greyed Out?
A disabled or unavailable Restart option can happen when:
- The service is already stopped
- Your Windows account lacks sufficient permission
- Windows is currently changing the service state
Try opening Services with administrator privileges.
If Bluetooth Support Service is stopped, use Start rather than Restart.
If the service still cannot be controlled, inspect the Bluetooth driver in Device Manager.
What If Bluetooth Still Does Not Work After Restarting the Service?
If you have followed the main how to restart Bluetooth service Windows steps and Bluetooth still fails, the service is probably only one part of the problem.
Work through the following fixes in order.
1. Turn Bluetooth Off and Back On
Open:
Settings > Bluetooth & devices
Turn Bluetooth off.
Wait approximately 10 seconds.
Turn it back on.
Then try reconnecting the accessory.
2. Remove and Pair the Device Again
If a device appears in Windows but refuses to connect:
- Open Settings > Bluetooth & devices.
- Find the device.
- Open More options.
- Select Remove device.
- Select Add device.
- Pair it again.
Removing and re-adding the device can resolve corrupted or outdated pairing information.
3. Run the Bluetooth Troubleshooter
Windows 11 includes an automated Bluetooth troubleshooter through the Get Help app.
Use it before making major driver or system changes because it can identify and attempt to correct common Bluetooth problems automatically.
4. Check the Bluetooth Driver
If Bluetooth Support Service restarts successfully but Bluetooth still fails, check the adapter driver.
Open:
Device Manager > Bluetooth
Right-click the Bluetooth adapter and choose:
Update driver > Search automatically for drivers
A newer driver may also be available from your PC manufacturer’s official support website even if Windows reports that the current driver is already installed.
Avoid unknown third-party driver download sites.
Prefer:
- Device Manager
- Windows Update
- Your PC manufacturer’s official support page
5. Roll Back the Bluetooth Driver After an Update
Updating is not always the right answer.
If Bluetooth worked before a recent update:
- Open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter.
- Select Properties.
- Open the Driver tab.
- Select Roll Back Driver, if available.
- Follow the prompts.
Consider rollback especially when Bluetooth stopped working immediately after Windows Update or a driver update.
The Roll Back Driver option may be unavailable if Windows does not have an older version stored.
6. Check Windows Update
Some Bluetooth drivers and compatibility fixes are distributed through Windows Update.
Open:
Settings > Windows Update > Check for updates
Install applicable updates and restart the PC if prompted.
7. Verify Airplane Mode Is Off
Press:
Windows + A
Make sure Airplane mode is disabled.
It is a simple check, but it can save time when Bluetooth appears to have suddenly disappeared or stopped connecting.
8. Check Bluetooth Power Management
Power-saving behavior can contribute to repeated Bluetooth disconnections.
Open Device Manager, expand Bluetooth, and open the affected Bluetooth device’s properties.
If a Power Management tab is available, look for:
Allow the computer to turn off this device to save power
Temporarily clear the option and test Bluetooth again.
This can be particularly useful when Bluetooth:
- disconnects after inactivity
- stops working after sleep
- repeatedly reconnects
- behaves differently when the laptop is on battery power
Not every Bluetooth adapter exposes this option.
9. Check Energy Saver or Battery Saver
Power-saving mode itself can also affect Bluetooth connectivity. If Bluetooth becomes unreliable while your laptop is conserving power, temporarily disable Energy Saver or Battery Saver and test again. If the connection stabilizes, power management may be contributing to the problem.
10. Bluetooth Connected but No Sound
If your Bluetooth headphones show Connected but you hear no audio, restarting the Bluetooth service may no longer be the relevant fix.
Check Windows audio output.
Open:
Settings > System > Sound
Under Output, select your Bluetooth headphones or speaker.
Also verify:
- Windows is not muted
- Device volume is high enough
- The Bluetooth accessory itself is not muted
- Another speaker is not selected as the active output
Connected but no sound and Bluetooth cannot connect are different problems.
11. What If Bluetooth Completely Disappeared?
A missing Bluetooth toggle usually deserves more than repeated service restarts.
If Bluetooth has disappeared:
- Run the Bluetooth troubleshooter.
- Open Device Manager.
- Check whether the Bluetooth adapter appears.
- Update its driver.
- Check Windows Update.
- Verify Airplane Mode is off.
- Restart Windows.
If Windows cannot detect the Bluetooth adapter at all, repeatedly restarting Bluetooth Support Service is unlikely to fix the root cause.
12. Reinstall the Bluetooth Driver
If updating or rolling back the driver does not work, reinstalling it may help.
The general process is:
- Open Device Manager.
- Expand Bluetooth.
- Right-click the Bluetooth adapter.
- Select Uninstall device.
- Restart the PC.
Windows normally attempts to reinstall the Bluetooth driver after the restart.
Because driver removal is more disruptive than restarting a Windows service, try the service restart first.
13. What If Windows Does Not Reinstall the Driver?
If the adapter does not return after rebooting, first check Windows Update and your PC manufacturer’s official driver page.
You can also open Device Manager and scan for hardware changes if necessary.
If the Bluetooth adapter remains completely undetected after driver troubleshooting, hardware should become a stronger suspect.
Should You Change Bluetooth Support Service to Automatic?
Changing Bluetooth Support Service to Automatic may look like an easy fix, but it is not necessary for every Bluetooth problem.
If Bluetooth normally works and only fails occasionally, restarting the service is usually a better first step than changing its startup behavior.
Also remember that Bluetooth User Support Service (BluetoothUserService) is a separate per-user service. Seeing it set to Manual does not automatically mean something is wrong.
A better approach is to troubleshoot in this order:
Restart Bluetooth Support Service → test your device → check the Bluetooth driver → change service settings only if the problem clearly points to startup behavior
If you are following a guide on How to restart bluetooth service windows, focus first on restarting the correct service rather than changing every Bluetooth-related setting in services.msc.
This keeps the fix simple and avoids unnecessary changes to Windows services.

When Restarting Bluetooth Service Is Most Likely to Help
Restarting Bluetooth Support Service is a strong early fix when:
- Bluetooth recently worked normally
- Several devices suddenly fail
- Bluetooth repeatedly disconnects
- Windows still detects the adapter
- Bluetooth appears enabled but does not behave correctly
- Connectivity fails after sleep or wake
- You want a reversible fix before rebooting or reinstalling anything
This is why learning how to restart Bluetooth service Windows is useful before moving to more disruptive driver or hardware troubleshooting.
When Restarting Bluetooth Service Probably Will Not Fix It
Look beyond the service when:
- Windows cannot detect the Bluetooth adapter
- Device Manager shows an adapter error
- Bluetooth stopped working directly after a driver update
- The PC does not contain Bluetooth hardware
- Only one accessory is failing
- The accessory battery is depleted
- The device is not in pairing mode
- Airplane Mode is enabled
- Headphones are connected, but Windows has the wrong audio output selected
- The Bluetooth adapter itself has failed
The service can only manage Bluetooth functionality that Windows can actually detect and use.
Windows 11 vs Windows 10: Does the Restart Method Change?
The core how to restart Bluetooth service Windows procedure remains essentially the same:
Windows + R → services.msc → Bluetooth Support Service → Restart
The main difference in 2026 is operating-system support.
Microsoft ended standard Windows 10 support on October 14, 2025. Windows 10 PCs can continue to function, but long-term operating-system, security, and hardware-vendor support should be considered when diagnosing recurring Bluetooth problems.
This does not mean Bluetooth immediately stops working on Windows 10. It simply makes current drivers and hardware support increasingly important.
Best Order to Troubleshoot Windows Bluetooth
After trying the core how to restart Bluetooth service Windows method, avoid jumping between random fixes. Use this troubleshooting order instead:
- Confirm Bluetooth is enabled.
- Make sure Airplane Mode is off.
- Turn Bluetooth off for about 10 seconds and turn it back on.
- Restart Bluetooth Support Service.
- Test the accessory.
- Remove and re-pair the device.
- Run the Bluetooth troubleshooter.
- Check Windows Update.
- Update the Bluetooth driver.
- Roll back the driver if the problem started after an update.
- Check Device Manager power-management settings.
- Test without Battery Saver or Energy Saver.
- Restart Windows.
- Reinstall the Bluetooth driver if necessary.
- Install the correct manufacturer driver if Windows does not restore it.
- Investigate hardware if the Bluetooth adapter remains undetected.
This order starts with the simplest reversible fixes and moves toward driver and hardware troubleshooting only when necessary.
Common Mistakes to Avoid
If you are learning How to restart bluetooth service windows, keep the troubleshooting simple and avoid unnecessary system changes.
- Restarting the whole PC too early: Restart Bluetooth Support Service first.
- Changing every Bluetooth service: Focus on Bluetooth Support Service, not every Bluetooth entry.
- Assuming Manual means broken: Bluetooth User Support Service can legitimately use Manual startup.
- Ignoring driver issues: If Bluetooth failed after an update, check whether driver rollback is more appropriate.
- Using random driver websites: Prefer Windows Update, Device Manager, or the manufacturer’s official support page.
- Editing the Registry too soon: A normal Bluetooth service restart does not require Registry changes.
Start with the simplest fix, test Bluetooth, and move to drivers or hardware only if the problem continues.
Conclusion
