Microsoft, for a reason known only to themselves has left an ultra vital tool in the 32 bit version of Windows 10 Preview. Personally I have no idea what I would do without EDLIN.COM. It has been in all non x64 Windows/DOS version since oh, DOS 1!!
When are they going to remove the crap that is no longer needed? Most of the kiddies out there would not know what EDLIN is let alone know how to use it. CRTL + Z
