CMD set path problem

Ok currently when i go System Property's > Advanced > Environment variables

The "Path" variable has a lot of clutter in it

C:\WINDOWS;C:\WINDOWS\SYSTEM32;C:\PHP\;C:\Program Files\Common Files\Teleca Shared;C:\Program Files\QuickTime Alternative\QTSystem\;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Common Files\Roxio Shared\9.0\DLLShared\;"C:\Program Files\Zone Labs\ZoneAlarm\MailFrontier"

All of that
I have been reading that it should just be

C:\WINDOWS;C:\WINDOWS\SYSTEM32

But what effect will it have deleting the other stuff?

Thanks

I wouldn't bother. Looks like applications you've installed on your system have added to the path variable so that they can find their own files easily. Deleting these other entries may cause your applications to malfunction.
