Click Performance, which should be on the left, and then on the left under Tasks you should see Adjust Visual Settings.

Select Adjust for best performance and scroll to the bottom and check the box Use visual styles on windows and buttons.

Manage Startup Applications

Defragmentation

Click Defragment Now.
