Great script, I will save it for later usage!

But in the meantime I came to another solution:
Instead of modifying PATH systemwide, I modify it only for cmd.exe.

To achieve this, I set the registry key
"HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun"
to "%USERPROFILE%\autorun.cmd" and write in this file:

If there was already an old value in
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun
it will be saved to %USERPROFILE%\autorun.cmd, too

This autorun.cmd is like .bashrc on UNIX.
