Have done all that and it still 'hangs' on the welcome screen - I can bypass
it by using CTRL+ALT+DEL and opening the task manager, and have to say my
laptop is running quicker now but it's infuriating that it gets stuck on the
welcome screen (it's not stalling because the icon still spins round so it's
trying to log in!!).
Any suggestions as I don't want him to wipe the laptop and reinstall
everything if I can help it!!
