Command prompt got messed up?

-I recently downloaded a C++ compiler from Borland to start learning C++ programmming language. I'm not sure if it has anything to to with the problem but......yesterday I had to do various things in the command prompt in order to set-up the compiler....everything was working fine so, I decided to shut off my computer and test it out the next morning.
When I tried testing it out, I had to edit some files by putting "edit" at the beginning, and everytime I did this, it responded "'edit' is not recognized internal or external command, operable program or batch file." At this point I was like......wtf?. Then, I said to myself, thats weird, so I decided to check the problem.....reinstalled the compiler...still...same prompt. Wtf?. Then I said, ok, lets see if the command prompt is the problem....I type in "ipconfig" which is a commonly known command. Guess what Mr. Command Prompt says......"'ipconfig' is not recognized internal or external command, operable program or batch file."wtf!!!!

"Something messed with my systems path statement." I had to change a system variable named "path" in order to install the compiler, how can I now fix my command prompt and still have something to help me learn C++ programming.

try to check ur 'PATH' environment variable.

It should have at least this: %SystemRoot%\system32;%SystemRoot%;

Something messed with your system's path statement.
