Hello
I would like to start by saying I've been stupid. I'm hoping someone on here can help as it is beyond my knowledge. It started because I have XP home but wanted to be able to remote desktop from my laptop to the affected PC. I found this posy
http://www.geekport.com/2007/08/15/enabling-remote-desktop-in-xp-home/ and began to follow it. I edited the productoptions as stated. When I tried to press F8 on start up to use last know good configuration i couldn't as I have a USB keyboard.
(I won't go into everything or the silly reasons I did what I did next as I now know exactly what I should have done)
I went into ms config and selected selective start up and unticked all boxes then restarted. This didn't work obviously. I then found out about enabling USB support and enabled this. I then pressed F* and loaded last known configuration. There were other things I did between these two but I cannot remember exactly now. The long and the short of it is that I finally loaded last know configuration and a lot of things including internet, usb support for memory stick do not work. My simple way of thinking is that I have loaded the selective start up and cannot get back to the original start up with full support etc. The system restore had been turned off when I mucked about with start up and therefore I cannot restore. I have a start up disc that will restore to factory settings but i really do not want to do this.
Please can anyone help and believe me I have learnt a valuable lesson.
Ash.
