Re: 100% disk usage
There is one thing you can try though.
Press the Windowskey and R, then type services.msc .
Once a new windows opens look for superfetch and change start up type to Disabled and reboot. See if that helps sometimes it does. If it doesn't work then you can just got back into services.msc and change the Superfetch service back to Auto again.
