The old depends.exe is not working on Windows 10 at all. It hogs all processor power and hangs. There is an open source replacement called dependencies, though. That one also works on Win 10.
But for fast checking of dependencies of a certain dll, you can also use dumpbin, which comes with Visual Studio. Just open the command line from VS, and put this into the shell:
dumpbin /dependents path\to\your.dll
If you’ve got a git-bash with version >= 2.18 on your windows machine, then ldd can do the same for you.
ldd ./path/to/your.dll
