Customer Question

I was online with a technician this morning to replace my Windows 7 Ultimate that seems to be corrupt. The new license key was checked and it is a valid key. The technician helped on my PC to download a replacement .iso file which is now downloaded but I do not know how to install it. it is on my desk top now.
JA: Just to clarify, what's the make and model of your computer? What version of Windows are you running?
Customer: This PC was made for me in 2011. The Windows 7 Ultimate came with it. It is only now when I tried to upgrade to Windows 10 that I was advised that the Windows 7 on the PC is invalid (6 years later). I am running Windows 7 Ultimate (which I was advised this morning is corrup, hence the new donwload).
