Hello , i updated my pc yesterday and saw it was like a big update cause it was copying all my files and restarting many times. After the update finished i shut down my pc. The next day turn on my pc and see some visual differences and some problems, first my mouse didnt work correctly and when my friend tried to skype me i could not answer cause there is a problem with audio devices.

Now i dont have sound my mic doesnt work and i cant configure my mice settings.

If someone could help me with this problem ,i would be really happy.
