Thanks for the reply guys and yes I am using XP Pro but checked my reg and can not see msconfig in the folder suggested so I presume I must have uninstalled it. Funny also my windows help menu does not work aswell comes up with the same error. If I do a search for msconfig it finds it and have now created a short cut to my desktop, so it is there but cant seem to get it from my run cmd. Will try to resolve it from my XP Disc. Any more help would be apprecisted, Dave.
