Although it's not very common, it is possible for the Bluetooth® module in your wireless adapter to fail independently from the wireless side in the same card.
If you suspect this is an issue resulting from an OS update, we could confirm this by performing a system restore using any restore point predating the problem.
1. Select the Start button, type control panel and then choose it from the list of results.
2. Search Control Panel for Recovery.
3. Select Recovery > Open System Restore > Next.
4. Choose any restore point with a date previous to the issue, and then select Next > Finish.
If after performing this restore the issue continues, you could give another try to a clean installation using the latest drivers for your adapter. But at this point, it might be good to engage your motherboard manufacturer for warranty support, it might be necessary to replace the wireless adapter.
