5 Ways to fix Bluetooth in Windows 10

Bluetooth is to devices as bridges are to banks of a river, a medium of connection. Technically, Bluetooth is defined as a short-range wireless connection between electronic devices like mobile phones, computers, tablets etc. This connection can be used to transfer files from source device to the device it is connected to. Bluetooth has wide range of applications and now-a-days all devices are getting an in-built Bluetooth system. Devices like headphones and earphones are also getting a Bluetooth system built in to make it more user friendly.

When Windows 10 was launched and people started installing it as fast as they could, they were met with some serious bugs and troubles, one of it being the problem with Bluetooth devices and its connections. Apparently, after the upgrade, Windows 10 was completely ignoring various Bluetooth devices and was not connecting to most of the gadgets. Error messages like “Bluetooth unable to connect”, “Bluetooth not detecting devices”, ”Bluetooth is not available” or ”Bluetooth disappeared” were common in many systems.

If you are facing a problem like this, then this article has you covered. Stating the obvious, make sure Bluetooth is switched on in both devices and both the devices are recognisable.                                        The device which you want to connect must have a working Bluetooth.                                                                                                                             


A simple solution is to check for updates of your Bluetooth drivers and downloading the necessary updates. This is one of the easiest to solve and generally the only problem faced by the computer while you try to use your Bluetooth.

Driver updates for Windows 10 and many devices like monitors, printers, video cards etc. are automatically downloaded and installed through Windows updates. To update drivers manually follow these steps-

STEP 2- Find Bluetooth device, right-click on it and select the update driver option.

STEP 3- Select “Search automatically for updated driver software”.

STEP 4- Wait for the download of these updates to finish.

STEP 5- Restart your computer. Hope this will resolve err_cache_miss issue


If updating Bluetooth device wasn’t enough to get the job done, you can try reinstalling the drivers of Bluetooth. Here’s how it’s done-

STEP 1, and select it from the results.

STEP 2- Find Bluetooth device, right-click on it and press UNINSTALL.

STEP 3- Windows will ask for confirmation for the uninstallation. Click on UNINSTALL.

STEP 4- After confirming and uninstalling your Bluetooth driver, restart your computer.

STEP 5- When the computer will boot up, it will automatically attempt to reinstall the driver. If it                        does not, for some reason, visit your device manufacturer’s website and check if there is a new driver available for Windows 10.


There is a chance that maybe your Bluetooth device isn’t even running to begin with. This silly mistake should be rectified by enabling your Bluetooth device by following these steps-

STEP 1- Select the START button, type services.msc in search bar, and select it from the results.

STEP 2- Find the Bluetooth Support Service.

STEP 3- If this service is not enabled, for some reason, right click on it and select START. If it’s enabled, right click on it and select Restart.

STEP 4- Wait for the process to finish.

STEP 5- Restart your computer.


If all the fore-mentioned solutions didn’t work for you, try the Windows 10 built in Bluetooth troubleshooting tool. A troubleshooter is basically a program built to locate trouble and make repairs in machinery and technical equipment. To access it, simply

STEP 1- Select the START button then go to Settings.

STEP 2- Select Updates and Security > Troubleshoot.

STEP 3- Select Bluetooth, and go to Run the Troubleshooter.

STEP 4- Follow the on-screen instructions and allow the process to finish.

STEP 5- Restart your computer.


Although Bluetooth and power saving options looks completely unrelated to the naked eye but when power saving settings are on, it sometimes disables the Bluetooth device. Changing this setting can hopefully make your Bluetooth work again. Follow these steps-

STEP 1- - Select the START button, type Device Manager in search bar and open Device Manager.

STEP 2- When Device Manager opens, locate your Bluetooth and double click it.

STEP 3- When properties window opens, look for Power Management and uncheck Allow the computer to turn off this device to save power. Now click on OK to save changes.

STEP 4- Restart your computer.

These are a few ways to handle your Bluetooth connection or system problem on your own and trying to fix your problem manually. While it is almost certain that these fixes will probably solve your problems with your Bluetooth and Bluetooth devices, there can be some instances where the problem is not rectified.

If such a case appears (I HOPE NOT), try seeking professional technical help buy contacting your manufacturer (to check for faulty parts or tampered product) or an IT specialist (to check if any part is tampered or broken or if there is some other problem).

That’s about it, I certainly hope that at least one of these solutions helped you in resolving your problem.
