I have tried to figure this out on my own, but.... I have lost my use of Help and Support. I restored my system as far as I could go (Nov 2) and discovered that Help and Support didn't even work then, so I don't know when I lost this service, or what I did to lose it. I have since added two new keys to my registry that points to where helpctr.exe and msconfig.exe are located: C:\windows\PCHealth\HelpCtr\Binaries. When I click on Help and Support, the error message says the system service is not running. When I try to start the system service, I get an error 1083: the executable program that this service is configured to run in does not implement the service. The path to the executable (Help and Support properties) is C:\WINDOWS\System32\svchost.exe -k netsvcs. I don't know if that has anything to do with it. I am grasping here... I ran Panda Titanium 2006 for any viruses: nothing. I have also tried to rebuild Help and Support according to suggestions from this link (http://www.kellys-korner-xp.com/top10faqs2.htm), but nothing changed. Msconfig works if I click on it from within its location in Binaries, but does not work when I use Run - msconfig. It says it can't find it...? Any suggestions? Thanks.
