-1 PID of 4 no use. C:\blah>netstat -abon | more "Active Connections TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4 Can not obtain ownership information" and after clicking 'show processes from all users' in windows 7 task manager, task manager lists "System" for PID of 4. –

For example, the table below shows what's included in SYSTEM PID 4 (output from Process Explorer on a normally-running Windows 7 system). There is no one answer to all of the problems experienced by people who use Task Manager to see "SYSTEM" behaving badly.

tasklist /FI "PID eq 4" Another way to get the process ID using the port: Get-Process -Id (Get-NetTCPConnection -LocalPort 80).OwningProcess Check whether the port has ben reserved for use by another process with: netsh int ipv4 show excludedportrange protocol=tcp Also look in Resource Monitor to see if that gives you any more clues.

2013年1月1日 · Windows 7 - SP1 Over the last few days, I've noticed the hard disk light blinking away furiously. I checked the resource monitor tons of read/write activity: Image/System; PID/4. The apparently

Using Process Explorer I can see that a certain file is locked by "System, PID: 4". This blocks the VB.NET VS2012 IDE from recreating the file.

Not sure which program disabled it. I just typed services.msc in the Windows start menu. Then I located the service "Application experience" and restarted it.

2011年11月22日 · System (PID 4) sockets might be http.sys, in which case you can use netsh command given by PiBa-NL. But note there are a few parameters. It seems the defaults are equivalent to: netsh http show servicestate view=session verbose=yes The sessions view didn't help in my case, but this showed the PID: netsh http show servicestate view=requestq

On Linux, the process with the lowest PID is init with PID 1, since it is the first process that gets started after the kernel loads, and is responsible for starting all other processes. pi@raspberry:~ $ ps -ef --sort=pid | head -n 5 UID PID PPID C STIME TTY TIME CMD root 1 0 0 Jan22 ?

我的notebook 長期都顯示有一項system 程序 PID 4 NT Kernel & System長期占用CPU資源, 令CPU 長期處於turbo boost 最高頻率模式, 非常浪費電力. 已經嘗試安全模式, 以及選擇基本服務啟動, 情況一樣, 資源管理器亦沒有透露程序詳細資料, 該程式又無網絡、磁碟活動, 究竟係甚麼程序如此 …

4 Most probably, that's http.sys, the kernel-mode side of the new Windows HTTP stack. It does system-wide port sharing and caching for web servers who are his clients (think of it as a kernel-mode nginx reverse proxy where your web servers can register), but of course it doesn't play well with web servers which want to listen directly on HTTP ...
