I can't use my microphone

I had an update last night and now when I go to the Restore, it took away my Restore Points and I can't use my microphone. so I re-booted my computer and that didn't help. I unplug the microphone and plug it back in which didn't help. I check my USB slot and it works so I can't figure out what's wrong?

What is Make and Model # of your Mic?
Have you gone to the Mic's Manufacturer's Download site and download the latest Driver?

Press the Windows Key +X choose Device Manager.
Here ,Are there any devices, especially under Universal Serial Bus Controllers with a yellow marks? These devices need drivers installed from the manufacturers web site.

You can also try the Mic on another computer for a test.
