Hello Bethany_13
Welcome to the Microsoft Community.
It sounds like you're facing a Bluetooth device conflict on your Dell Inspiron laptop, where your headphones disconnect when your Bluetooth mouse is connected. This issue could be related to Bluetooth resource management or interference between devices. Here are some steps you can try to resolve the problem without reinstalling the latest update:
- I understand that you are using a DELL laptop. Regarding DELL notebooks, DELL officially provides SupportAssist. You can download it and update all your drivers. There is also a fault repair function on it. SupportAssist for Home PCs | Dell USA Disclaimer: This is a non-Microsoft website. The page appears to be providing accurate and safe information.

- Change Bluetooth Connection Settings:
- Press "Win+Q", search and open "Settings". Navigate to: Settings > Bluetooth & Devices > Devices.

- Adjust Power Management Settings:
- Press "Win+Q", search and open "Device Manager".
- In Device Manager, under Bluetooth, right-click on your Bluetooth adapter and select Properties.
- Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power."
- Remove and Re-pair Devices:
- Remove both the mouse and headphones from Bluetooth & other devices in Settings.
- Restart your computer.
- Pair the headphones first, then the mouse, to see if the issue persists.
If there is anything not clear or I can't understand your problem, please do not hesitate to let me know.
