How to reconnect to a already paired bluetooth A2DP headset?

Thank you that was very helpful.  I was looking for a connect button in Windows 10 but could not find it and kept removing the device and re-pairing my headset to get it working with Windows 10 again.  Now I just have to right click on the speaker icon, select playback devices then right click on the headset and click connect.  Brilliant much appreciated.  I think that the Microsoft development team should put a connect / disconnect button on the Bluetooth page under settings, but this work around will work for me.

In case anyone is running windows 10, the following instructions worked for me:

1. Click to open the notification center
2. Click on "Connect" (the icon with a speaker and a monitor)
3. Select your previously paired device.

I was becoming tired of removing and repairing my devices each time but this works like a charm !

Surprisingly in windows 7 there's no way of connecting to a already paired headset. (when you right-click on the headset icon under bluetooth devices there's no 'connect' options.). Now one might ask why don't you restart the headset? But it'll never work since headset will try to connect to the last device it connected. (in this case my mobile phone). Only way I can connect my headset to Windows 7 now is putting the headset back into pairing mode, deleting the headset from windows, and re pair it. This will take a lotof time and this will also install drivers for four bluetooth profiles headset supports. (A2DP, AVRCP, handsfree, headset). (This will also create a system restore point to make things slower).

I just had the same problem and am just as surprised that windows has no "Connect/Disconnect" interface solution but I have just found the solution. Forget all the re-installing process. Simply put off your PC's bluetooth connection and put it on again while your headset is ready to connect. Windows will automatically recognize the device and ping it. 

Hope this helps some troubled soul. I have this tried and tested on Windows 10. I assume it is the same with the older Win 7.

I use a bluetooth stereo headset with my Laptop running Windows7/Fedora 12 and also with my mobile phone and with my ipod. I want to connect my headset to one of above devices at a time.

I have paired my headset with all of above devices (Windows 7, Fedora 12, my mobile and my ipod). Suppose I've currently connected my headset to the ipod and now I want to use it with my mobile. All I have to do is disconnect headset from ipod and connect it to my mobile. (The 'connect' and 'disconnect' facilities are there in both my ipod and mobile).

Suppose now I want to use the headset with Windows 7. (it's already paired and shown under Bluetooth Devices). Surprisingly in windows 7 there's no way of connecting to a already paired headset. (when you right-click on the headset icon under bluetooth devices there's no 'connect' options.). Now one might ask why don't you restart the headset? But it'll never work since headset will try to connect to the last device it connected. (in this case my mobile phone).

This will take a lotof time and this will also install drivers for four bluetooth profiles headset supports. (A2DP, AVRCP, handsfree, headset). (This will also create a system restore point to make things slower).

Similar to my mobile phone and ipod in Fedora linux it's just a matter of right clicking bluetooth icon and selecting 'connect'. I have not used windows for a long time and may be I miss something very obvious or the way Windows 7 bluetooth works is very frustrating.

I use Windows 7 professional in a Dell Inspiron laptop. The bluetooth stack used is the one supplied with Wndows 7.
