I am in a couple forums and almost on all of the forums it states their is a way to do a non destructive system restore where if you did a system restore if you have a file like windows office you wouldnt have to reistall the applcaiton so if you dont have a product key for it then you would loose the software...

Is this true or am i right to think that its a myth/////

and if that true about it being a myth. what would be the best method to solve the problem assuming you would have that problem iwth the windows office software
