I have a Dell Laptop which I am thinking of replacing and would wish to make it available for use by a family member ( one yet to be decided). However, I would wish to clear out all personal items, such as E/.mails, Pictures, Documents, etc and am wondering if perhaps I should endeavour to return the machine to original factory settings and then re-load all that I consider is appropriate. My fear is that I will mess-up things and loose Windows Vista Home Premium in the process; along with Internet Explorer.
