my computer is a pesario  CQ57 windows 7. i Ihave just got sky drive and sent an email with photo email.to check I sent it properly  I went to sent box. beside the title on the photos was written "download" which I clicked . I got access to all areas of my computer- files docs everything. does this mean the recipient will be able to access my whole computer? I am most concerned that I could have done something that stupid. do I change my password if this is the case. it all looked straightforward to me . can u help please? This has never happened with my other emails.
