Unfortunately, I have a computer at work that runs W8. I would PAY money to be able to revert to W7, but HP doesn't offer that possibility. And yes, W8 "is" that bad.
Right now, I am trying to upgrade that machine to 8.1 (thus far unsuccessfully) in hopes that some of the changes move at least slightly in an acceptable direction. NOTHING about Windows 8 is in the least attractive if you need to get real work done.
Fortunately, that machine is NOT my main desktop, which has W7.
Download a live Linux distro and boot up from that instead if possible. Since everything runs off of the disc, it will not touch your system files and you might be a whole lot happier using that instead.
