Run cmd as administrator: Start > Search cmd > Right click and choose "Run as administrator" (or press Ctrl + Shift + Enter)
Input netsh winsock reset, then press enter
Restart computer after that
Hi Pete,
You can use a totally free driver manage and update tool called DriveTheLife to remove unused drivers completely and easily. Download DriveTheLife from official site. Google it, you can get it.
