If I am running an alternative shell and not Windows Explorer and Im using a different Filemanger than Windows Explorer, would I still be as vulnerable as users who are running it as their default shell?

It depends.  Some alternative shells hook into the same libraries of Windows as Explorer.  If a vulnerability is found in one of those libraries, you're just as vulnerable.

You'd have to look at them on a case-by-case basis.

Use depends.exe to look at DLL dependencies for Explorer (look at explorer.exe).  Then, compare it to your alternate shell of choice.  If you see any common dependencies, then a vulnerability in one of those DLLs could affect both.
