Windows 10: why is my processes in task manager showing ports like 100028,103904 ?

I am on W10 x64. This is unusual . I haven't seen port number that high .I know only 65535 are possible in any windows system. I am attaching a screenshot

why is my task manager under processes tab disk 50% under performance tab disk 100% and computer freezing

Hello Kay,

If the tasks you're doing requires more resources than the capacity of your hardware, then you might experience lagging issues. However, you can still perform your tasks. We recommend that you see this article:

why is my task manager under processes tab disk 50% under performance tab disk 100% and computer freezing

In task manager under processes tab my laptop says disk 50% under performance tab it says 100% i changed my hard drive because my old hard drive had bad sectors. This hdd has less space then my old one the old one didn't freeze like this one does but the
computer freezes for a second and sometimes longer. The disk usage isn't always 50% but when it does get that high my computer freezes, this happens when I'm downloading, installing or sometimes idk what causes it. I have a G75vx ASUS running windows 10 hdd
500 gb

 

It's a Process ID (PID) not port number.

 

Microsoft has made it quite clear that we should attach to significance to the size of process id numbers. While the numbers are unusual I don't think they mean anything, at least none that has been documented.

In the past Windows tried to keep these values low but this was only for cosmetic reasons. Maybe that has changed?

In Linux a process ID cannot exceed 65535 but that is not the case in Windows. I have heard of process IDs over 400000 in busy servers.

Edit: Port numbers , as used in TCP/IP networking, are limited to 65535 but a PID is something very different and not related in any way.

A PID is an arbitrary number that uniquely identifies a process or thread. When the process or thread terminates the number is eventually recycled. It is officially documented as a DWORD, meaning it can have a value from 0 to 4,294,967,295. Officially a PID can be any value in that range. Currently it is a multiple of 4 but that is merely an implementation detail that could change at any time. In Windows 95 PIDs in fact had values in the high end of that range but as Task Manager did not show PIDs that was not well known. In early beta versions of Windows 2000 PIDs often had high values, causing concern that this indicated some kind of error. So in later versions Windows tried to keep the values low, purely for cosmetic reasons. That policy may have changed. But don't expect to see documentation regarding changes in undocumented behavior.
