I have a friend's Dell Inspiron M5040 laptop computer running Win 7 Home Premium. She has completely trashed the OS and I have tried everything to get the laptop up and running to no avail. What I am looking for is a web site where I can safely download a new copy of Win 7, place the image on a disk and reinstall the OS on the laptop. I recall doing this a couple years ago and used the product code that came with the computer and everything worked fine. I would like to do the same with this laptop - download a legit copy of Win 7 and use the product code that came with the computer. The problem is that I do not recall the web site I downloaded the software from. When I Google for some sites it appears the sites are 3rd party distributers and want money or are loaded with unwanted programs. Could someone recommend a site to download Win 7 safely without all of the add-ons. Thanks for your help in advance.
