I built my PC on July 25th and Windows 10 came out on the 29th, so I should've been eligible to get it right?
I also bought a copy of Windows so it wasn't pirated
You don't see the little windows icon in the bottom right hand corner in the system tray?
See if any of this helps http://answers.microsoft.com/en-us/windows/forum/windows_10-win_upgrade/i-want-to-reserve-my-free-copy-of-windows-10-but-i/848b5cce-958b-49ae-a132-a999a883265b
IS windows up to date all the way?
How do I check that?
Make sure windows update is fully up to date, the windows 10 downloader is installed from an update. Go into control panel and type in the search field in the top right corner 'windows update' and then press check for updates now. Probably a good idea to make sure the update settings are set to automatically install updates
