So I reformat my computer recently, thus expect that all my files swiped out except for my pictures as it was saved in my external hard drive. The only important thing that how I to get it back is my Microsoft Windows where I can write and record my expenses. I need to have that and I don’t know where to get it then I realized I have a CD of Microsoft Windows in my closet drawer, my husband handed it over to me that last time he was here. So I installed it in my computer, it worked however I don’t have the product key and I don’t have any idea what email that my husband saved it there. I asked him the product key and he gave me some but those didn’t worked, it says that the product key I encoded does not belong there. My husband just then told me that he will try to find the case in the storage room. I will just have to wait.
