How can recover windows 7 original operating system which is formated if we inst

Combine the the human qualities of cheap, stupid, and the larceny of wanting something for nothing (variation is MS is big and rich I am entitled to steal from them) and you get a reason. Ssjensheer I suggest you purchase an OEM version and clean install it on a formatted drive. Of all the software a system uses you would think people would want their OS to be secure. BTW it is not so hard to embed malware ito a pirated version of the OS. GL to you.
