Foreword

I used to useWindows 7system. I installedWindows 10some 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 commandnetstat -ano, I found that port 80 is occupied by the System process with pid 4. According to previous experience: one is occupied byIIS; the other isSQL Server Reporting ServicesReporting service occupied.

Note: If the system isWindows 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?

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.
