Windows 10: Sluggish and no games work

[legendaryc4]

I have recently upgraded to Windows 10 from Windows 7. Windows 7 ran fast, played games , and worked. I upgraded to Windows 10 because others were saying "If you love Windows 7 you'll love Windows 10!" also because of DirectX12. So I install Windows 10, I was very excited everything looked amazing. I restart the system because things were going sluggish. Systems turns back on it's a little bit better but Windows 7 would be faster. I try opening Dragon Ball Z Xenoverse, black screen. I try opening Titanfall I get under 10 fps on low settings 1600x900 on Menu. I try playing Battlefield 4, when loading the level everything went fine until I randomly got 1 FPS music stuttering. Level never loaded. Sometimes my CPU is at 60 or at 99% when just browsing the web... Never happened on Windows 7. Is there anyway I can get things to work or restore back to Windows 7 without losing any files?
SPECS

Yes, you can uninstall W10 and roll back to 7 if you haven't cleaned up the installation files.

However, it sounds like you need to look and see what process is eating up your CPU power from Task Manager. Find it - and kill it. I wonder if it's indexing stuff - mine did that for a couple hours when I upgraded.
