So my PC is showing that I had a backup of windows 7, even though I never installed windows 7 on this system. I bought the components and assembled this PC earlier this year.
I am having windows 10 64 bit pro on this system currently. I never tried to install windows 7 in this.

My old PC had windows 7 but that's completely irrelevant, since I didn't reuse any component, not the hard drive. I didn't copy the data too. (The old hdd data was already lost forever).

Why does my pc think windows 7 was previously installed?
