If the computer did not come with an XP disk then there is probably a way to do a Factory Restore within the computer. You could have a look in the manual for this. If you don't have a hardcopy manual then there is probably one on the computer somewhere.
Or you could download one from the manufacturer's website. Dell computers, for example, have a Factory Restore that you can access by pressing on boot. Acers have a Factory Restore that you can find in All Programs, under Acer Utilities I think.
Other makes are different. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
