On my Windows 7 machine, using the System Properties > Environment Variables tool, I try to add %USERPROFILE%\Bin to the system variable PATH. For some reason, that doesn't work, even though %SystemRoot%\system32 works fine.

When I try to run commands from the console, files in my Bin folder are not found, even though files in the System32 folder are found.

The only difference between UserProfile and SystemRoot that I can see is that the former is a user variable while the latter is a system variable.

I i write echo %USERPROFILE%\Bin it yields c:\Users\zano, and if I add c:\Users\zano\Bin explicitly, everything work fine.

What's the problem here?
