Windows 10: Bluetooth adapter isn't detected after rolling back to windows 10

So around a month ago, I rolled back my HP ProBook 4440s from Windows 11 to Windows 10. I had updated it from win10 to 11 and it didn't show any problems, but on rolling back I had to reinstall windows from a backup bootable USB device. So, I went ahead to connect my headphones and didn't see the option in the action center. Went into the settings, no option to turn on bluetooth as well, and it shows "Couldn't connect". In the device manager too I don't see any bluetooth device detected and running the troubleshooter shows that my laptop doesn't have bluetooth ability and to use an external

Bluetooth in windows 10

My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

USB-BT211 Mini Bluetooth Dongle - Support

• Support A2DP for Wireless Stereo Music Playback

Edit: This is a dongle with old BT version I see now, but I'm sure you can find a Asus BT4.0 version.

Edit2:

@aasim1111 I have this one, it doesn't show that it supports A2DP in the specs but I think it'll work, otherwise send a mail to Asus and ask.

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.
