Solution to the problem that port 80 under Windows is occupied by the System process with pid 4 windows7 download windows xp system download windows7 ultimate version

Foreword

I used to use Windows 7 system. I installed Windows 10 some time ago, and I haven’t had time to set up the php environment yet. I tried a lot today, using nginx+php, the port is 80 (iis service has been stopped), nginx just can't start, and nine times out of ten, the port is occupied.

I found

Using the port mapping command netstat -ano, I found that port 80 is occupied by the System process with pid 4. According to previous experience: one is occupied by IIS; the other is SQL Server Reporting Services Reporting service occupied.

Note: If the system is Windows 7 and below, there is basically no problem in solving the above two.

Question

Both the two services mentioned above have been stopped. What program is occupying the port?

Method

• Use HTTP command netsh http show servicestateLook in detail, you will find the information about port 80, write down the version.
  

• Then, search down and find the version corresponding to the above
  

• Open Task Manager, select Details, find the corresponding process, then right-click Go to Services
  

• After going to the service, right-click to stop the service.
  

Call it a day

Everything is ready, you can safely code.

The above introduces the solution to the problem that port 80 is occupied by the System process with pid 4 under Windows, including Windows content. I hope it will be helpful to friends who are interested in PHP tutorials.
