Bluetooth suddenly stops working on Windows 10 — it’s a common issue, and usually not as complicated as it seems. Sometimes it's a small driver problem, other times it could be a system glitch or hardware misconfiguration. Let’s break down the most likely causes and how to actually fix them.

Check if Bluetooth is Enabled and Supported

Before diving into advanced fixes, make sure your PC even supports Bluetooth and that it's turned on. Many desktops don’t come with built-in Bluetooth modules, and some laptops have a physical switch or function key combo (like Fn F8) to toggle it.

• Look for a Bluetooth icon in the taskbar (near the clock). If you don’t see it, click the up arrow ^ to reveal more icons.
• Press the correct function key combination to enable Bluetooth if your laptop has one.
• If your computer doesn’t have Bluetooth built-in, you can use a USB Bluetooth adapter — just plug it in and Windows should recognize it automatically.

If you're sure Bluetooth is supported and enabled but still not showing any devices or turning on, move on to the next step.

Restart Bluetooth Services via Services Manager

Sometimes the Bluetooth services in Windows stop running or get stuck. Restarting them manually can often resolve the issue.

Here’s how:

• Press Win R, type services.msc, and hit Enter.
• Scroll down and look for these services:
  • Bluetooth Support Service
  • Bluetooth User Support Service
• Right-click each one and select Restart. If they’re already running, try stopping and starting them again.
• Set their startup type to Automatic so they run every time you boot.

This often fixes issues where Bluetooth appears grayed out or fails to detect devices.

Update or Reinstall Bluetooth Drivers

Outdated or corrupted drivers are a major reason Bluetooth might stop working.

To check:

• Press Win X and open Device Manager.
• Expand the Bluetooth section.
• Right-click each device listed and choose Update driver > Search automatically for updated driver software.

If updating doesn’t help:

• Try uninstalling the Bluetooth drivers entirely.
• After uninstalling, restart your PC — Windows will attempt to reinstall the drivers automatically.

If Windows doesn't find new drivers, go to your laptop or motherboard manufacturer’s website and download the latest Bluetooth drivers directly.

Run the Windows Bluetooth Troubleshooter

Windows 10 comes with a built-in troubleshooter specifically for Bluetooth issues. It can catch problems you might miss.

How to access it:

• Go to Settings > Update & Security > Troubleshoot.
• Click on Bluetooth and then Run the troubleshooter.
• Follow the prompts and let it scan for issues.

This tool often catches small glitches, like incorrect profiles or missing components.

Check for Windows Updates and Known Issues

Microsoft regularly releases updates that include bug fixes and compatibility improvements.

Go to:

• Settings > Update & Security > Windows Update.
• Click Check for updates and install any available updates.
• Restart your PC after installation.

Also, occasionally there may be known issues with certain Windows versions affecting Bluetooth. Check Microsoft’s support site or forums to see if others are experiencing similar problems after an update.

Fixing Bluetooth issues on Windows 10 usually involves checking hardware status, restarting services, updating drivers, and using built-in tools. Most of the time, one of these steps will get things working again.基本上就這些。
