By Windows Resource Monitor (win + R: resmon) can see that 80 port is already occupied, the next figure is already solved, could not capture the situation is occupied, the solution is given below.
PS: posted two nice windows cmd command
View occupy the port program PID (last column represents PID):
-aon netstat | findstr " port number "
Corresponding PID viewer:
tasklist|findstr "PID"
Open Device Manager, click on the menu bar View -> Show hidden devices , this time you can see non-Plug and Play Drivers , start, find HTTP , switch to double-click the Driver tab , set the type to have disable , OK, reboot the system . (Note: In theory, you can also directly point to stop, but then I always get stuck click on the system to be set off, or otherwise, after the system has restarted 80 is occupied.), HTTP drive is usually a printer device port occupancy caused.
