What is process PID 4? PID 4 is the Process ID for the Windows SYSTEM process. It’s a lot like PID 1 on Unix systems, in fact. A lot of services run under PID 4.

What is System PID 4 must be killed?
If it is a System Process—PID 4—you need to disable the HTTP. sys driver which is started on demand by another service, such as Windows Remote Management or Print Spooler on Windows 7 or 2008.
What is System PID?
In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels—such as those of Unix, macOS and Windows—to uniquely identify an active process.
How do I fix system high disk usage?
System process High Disk or CPU usage
- Update old drivers or roll back to the earlier update.
- Clear the Page file at shutdown.
- Don’t use a Power saver plan.
- Use SysInternals Process Explorer.
- Disable Idle task.
- Use Event Tracing for Windows to capture CPU sampling data.
How do I check if Windows is port 80?
To check what’s using Port 80:
- Open Command Line and use netstat -aon | findstr :80. -a Displays all active connections and the TCP and UDP ports on which the computer is.
- Then, to find which programs are using it, take the PID number and put them in tasklist /svc /FI “PID eq [PID Number]”
- Closing programs should resolve.
Why is system constantly writing to disk?
There are several potential causes for high disk usage in Windows 10, but most come down to the same basic idea: Too many things are running for the computer to handle. One common cause is swapping or paging. As Windows works with that information, it constantly reads and writes to swapfile. sys, driving up disk usage.
What PID should system always be?
The system process is responsible for the system memory and compressed memory in the NT kernel. The system process has always the PID 4 (Process Identification) in the Windows Task Manager, otherwise it is malware.
Is 0 a valid PID?
PID 0 is the System Idle Process. Since that process isn’t really a process and never exits, I suspect that it is always the case.
Why is system using up so much disk space?
Everything that can’t be fit into memory is paged to the hard disk. So basically Windows will use your hard disk as a temporary memory device. If you have a lot of data that has to be written to disk, it will cause your disk usage to spike and your computer to slow down.
What to do about excessive disk access with PID 4?
Using the Resource Monitor I detected excessive disk access from the system process with PID 4. Following some tips, I disabled the anti-virus on the System Volume Information folder, hoping it will help (I don’t want to disable system restore).
Where does the high disk usage come from?
High disk usage (100%) coming from System process (PID 4) with zero indication of why. My system: MSI GTX 970 Golden Edition @ 1.3GHz 256GB Samsung 850 Pro SSD for OS drive. 2x 3TB WD Red drives for data. The data drives are what is being used 100%, not the OS drive.
Which is the process ID for Windows 7?
PID 4 is the Process ID for the Windows SYSTEM process. It’s a lot like PID 1 on Unix systems, in fact. A lot of services run under PID 4. – sysadmin1138♦ Aug 19 ’12 at 13:13.
How many MBS does PID 4 read per second?
When running a simple extraction of a ZIP file, I can see the WinRAR reading a few hundreds KBs per second from the file, but PID 4 reads dozens of MBs per second from the same file. After cancelling the operation, PID 4 keeps accessing the file for around 30 seconds, reading many MBs per second.
