As a specific example, I was troubleshooting something related to javaws.exe (Java Web Start) and found it in two places:
I'm guessing the Java installer put it in both folders. Is it also in the System32 folder because C:\Windows\System32 is in the PATH? Which means you can call
javaws from a cmd shell without specifying the absolute path (is that correct?).
My background is mainly Linux, so just trying to understand Windows a little deeper. Thanks!
