I was searching for a way to find all the processes running right now, who has loaded particular DLL.. And found a really good command that shows really useful output..
You dont have to install anything on your windows, just go to command prompt and fire command.
PS: Replace wbemsvc.dll with DLL in question.
The same command can be used to see services each process is hosting..
There are also many other useful parameters that you can pass with tasklist like, see processes list running on some other machine (provided you can give correct credentials to connect to that machine!)
