This isn't exactly an advertised fact, and you may already be aware of this, but......
Microsoft will allow users of Windows 8 Pro to downgrade their new PCs to Windows 7 or even Vista, according to the operating system's licensing agreement.
Not surprisingly, users may not downgrade to the still-used-but-slated-for-retirement Windows XP.
So, if using legitimate copies of Windows is an issue, for you and you would rather use windows 7! You can legally do so.
