Got a Windows 8 PC just a couple of days ago, and I was going to make a new account. In the Start menu, I clicked my account at the top and then Guest. Quickly found out it's not what I wanted, and then restarted to see if I could make a new account from the first login screen. And now, I can't even log in as the admin. It just says the user service failed and sends me back to the login. If I input any other password, it'll say 'Welcome' and appear to be loading for around 10-15 minutes before simply going back to the login without any message. I also noticed that the icon at the bottom left does nothing when I click on it... And I've tried to boot into the recovery by Shift+Clicking Restart, and holding Shift and mashing F8 upon startup, but neither works. In fact, the latter method just hangs on a Gateway logo screen as long as I hold Shift, and will just boot into the login screen as usual when I let go. Really don't know what to do... Every method I've found online involved either logging in to a different account or recovery mode, but I can't seem to access anything at all.
