A friend has bought a 2nd hand HP Omnibook 6000 for their mildly autistic adult son.

They asked us to check it over and set it up for them - so we're doing what we can but have very limited knowledge about Windows in the home.

What would you suggest to make things work fairly easily?
I'm thinking codecs, common bits of useful software, security things (eg anti-spyware), anything that we can use to help them remotely (from a linux box!)

It has XP installed and working; we've set updates to be automatic. The AV is AVG free 8.0, they have Symantec on another machine and will probably use it on here (unless you have any suggestions).

I've added:
* Firefox
* OpenOffice

Thoughts?
