Service Control Manager transmits control requests to running services and driver services. It also maintains status information
about those services, and reports configuration changes and state
changes.

I got few questions

How frequently Service control Manager transmits Control request, does it check at regular intervals or for any changes?
I noticed once the SCM sends a request the service will enter
running or stopping state without any user intervention or any
failure action configured?

How frequently Service control Manager transmits Control request,

Why would it transmit control requests in ANY interval? It sends them when a control request is needed (i.e. user presses stop).

I noticed once the SCM sends a request the service will enter running or stopping state without any user intervention or any failure action> configured?

Yes. Is there a question here? Obiously - Service running, gets stp control request, status is shown as stopping. What is the question?

Windows – How to find what process is holding a file open in Windows

I've had success with Sysinternals Process Explorer. With this, you can search to find what process(es) have a file open, and you can use it to close the handle(s) if you want. Of course, it is safer to close the whole process. Exercise caution and judgement.

To find a specific file, use the menu option Find->Find Handle or DLL... Type in part of the path to the file. The list of processes will appear below.

If you prefer command line, Sysinternals suite includes command line tool Handle, that lists open handles.

Examples

c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "e:\" (finds all files opened from drive e:\"
c:\Program Files\SysinternalsSuite>handle.exe |findstr /i "file-or-path-in-question"
