How to know which DLLs are being used by a program in Windows?

From the command line run the following command syntax:

tasklist /m /fi "IMAGENAME eq [filename.exe]"

Replace the [filename.exe] above with the executable file name for which you need information.

For example: With Notepad.exe

Command:
tasklist /m /fi "IMAGENAME eq notepad.exe"

Sample Output:
