One last comment:
If you were my client, I would:
- Admonish you for not acting more quickly when you saw the white flag
- Tell you that if you did not have good backup of your data, you may have to suffer the consequences
- Bring your computer to my desk and re-install Windows 7
- I would also suggest to you that Windows 10 is very unlikely to be something that you will want to have. Don't experiment with it. Go find it in someone else's computer like a store and check it out. Then if you still want it, wait until the year is up before even considering it baked enough to want to have.
