How do remove the student version label in AutoCad?

The student version is marked "student version" for a reason. It is illegal to use for non-student work. 

If you have a legal copy of AutoCAD 2007, then saving your drawing as a DXF file and importing that DXF file into your 2007 version should offer you some way to delete those "student labels" while still having your basic geometry.

                              

                                                       Thanks & Regards
