It came with Windows vista originally. The product key is still on the warranty sticker on the laptop, but I got a free upgrade to windows 7 and obviously would rather go back to 7 than that god awful vista, but I moved and think the disk and that product key are probably at my parents house somewhere.
I have 2 DVD-Rs that look like they have Windows 7 boots burned onto them, but can I use these if I don't have a product key?
What are my other options?
Please help, in dire need of reformatting and would like to work on it this weekend.
