It would seem I've done something terrible to my computer. After the family computer's time came a few years ago, I cannibalized it to assist in making my new rig. (Mostly just the fans and the hard drives.) So now I have a new (for the most part) computer. The only old part is the hard drive. Having had difficulty with the old profile (also windows 7) I just plastered a new version right over top. I renamed the computer and created a new account. The only one (I thought) on the computer. Now back from the grave for revenge comes the old family computer, hilariously named "Sans Souci." I miss Ernest, and I earnestly long for my old (new) account.
I can see my programs in the C, D and G drives. (The D and G drives being the cannibalized parts.) My question is: Is there any way to return to my most recent version of windows, and how do I escape this blast to the past? Thank you very much for your time, I appreciate any help or advice you can give me.
