(This question is not a duplicate of Find out which process is locking a file or folder in Windows I am asking specifically about when PID-4 is locking it (besides the fact that i'm saying without using guesswork. And that question doesn't even mention PID-4))
When System PID 4 is locking a file or folder, How can I determine what program/process/service is locking it without guesswork?
For example , see this result from process explorer showing a file that may be locked.
Now, without any guesswork, how can I determine what is locking it? (When the only info I see from process explorer is that it's SYSTEM/PID-4)
Somebody asked if it is a duplicate of Process Explorer: How to find out what System PID 4 is The questoin is similar.. but there's no answer there that answered my case.. Also, the question there iis very simplistic and says "How could I find out which application "System, PID: 4" really is?"
I know that PID 4 isn't an application. It is something system related.. and may be a service.
So my question is not the same as that one. That one has misunderstandings about what PID 4 is and somebody could partly answer that question by just saying what it is and is not.
