there is no way (that I know of) to look at what your PATH was before it was destroyed and the PATH is often updated by installers (as it is with dmd).
If you haven't rebooted your machine yet - Windows stores a backup copy of the system registry hives for the "last known good configuration" boot feature. These copies are stored in C:\Windows\Repair (XP and before) or C:\Windows\System32\config\RegBack (Vista and after). You will not be able to access these files directly, though - you'll need to use a tool or risk a poweroff and boot from another OS. Once you have a readable copy, you can "mount" the hives to an empty key in your registry with RegEdit. PATH is located at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment (though you won't see CurrentControlSet in the mounted hive, it's a symbolic link of sorts to one of the ControlSetXXX keys).
