Dear Bore07tm
Welcome to Microsoft Community.
I understand that you have previously added and removed your Bluetooth device and you are moving pictures or documents with a message that the device is disconnected. The problem may be caused by residual Bluetooth connection information or corruption of system files. You can refer to the following steps:
- Open Device Manager, check Show hidden devices in the menu bar "View", check if there is a Bluetooth device you are using before, if so, uninstall its driver. After uninstalling the driver, see if the problem is solved.
- Create a local account Creating a new local account can help you troubleshoot problems caused by user profiles.Create a user account in Windows - Microsoft Support。 If the problem disappears after creating a new local account, the problem may be caused by missing or corrupted user profiles for the original account. You can transfer your existing data to a new account.
- Eliminating interference from third-party software Interference from third party programs can also cause problems.I recommend trying a clean bootwhich starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem. These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step. If the problem does not appear after a clean boot, the error is related to third party software. (If you have third party protection software installed, such as 360, McAfee etc., please uninstall the third party protection software before a clean boot)
If the problem is still not solved by the above steps, you can share the recent progress with me in the reply. I will work with you to try other possible solutions to resolve the problem.
Thank you for your patience and understanding, and we look forward to your reply.
