cmd prompt not opening exe's

[sachinmehta]

hello everyone,

my cmd prompt is showing a very weird problem.
after installing an simulator for alarms, when i type notepad or
ipconfig on the prompt, then it replies back that an unknown command
has been given.

to make these applications work i have to type notepad.exe or
ipconfig.exe
i think the problem might be in the registry, but cant figure out
where...

can anyone please help me out with this?

thanks in advance,
sachin.

Search for the files you have to type EXE for.

Your looking for BAT, COM or no extension files of the same name.

If you find these you need to find the cause.

It seems you have a damaged or missing environmental variable
called %pathext%. Your problem is likely to go away after you
restore the variable. Here is what it normally looks like:

PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH
