關掉自動備份不能把系統恢復到你所需要的狀態。
先檢查一下你的設置看看是不是保留了太多的空間給系統恢復備份。
Start->Computer->right click->Properties->System Protection->Pick up your system drive under Protection settings->Click Configure button->Check Disk Space Usage and the Max Usage. 10% Max Usage should be enough. If it is too big set it back. Also check other non-system drives' settings. You could turn off Protection Settings for non-system drives if they are on and delete their restore points. If all the settings are ok, it may be other reason(s) that took space.
