HC-05 Bluetooth Module Windows 7 problems

If you have bought an Arduino bluetooth module (or whatever other device) and it uses the HC-05 chip, then you will probably have a problem establishing a connection with your computer. You will first establish it and shortly the connection will break.
This is because of the Windows 7 bluetooth drivers. I had some serious problems fixing this issue and there were a lot of people having the same issue.
So what is the solution: just install other bluetooth drivers or just install another OS like Ubuntu (it runs flawlessly ).
