Julia upgraded to Windows 10 and she doesn't like it at all. She wants to downgrade, but the problem is that she is past the 30 day downgrade window. Leo says that at this point, the only thing she can do is get out her Windows 7 disc, wipe the drive, and reinstall. Her computer may not have come with one, which is common. She did make system recovery discs onto a DVD, however. So it should be a matter of running the install, formatting the hard drive, and getting back up. She may want to put that recovery onto a USB key instead. It'll last longer.
