1) Connect a mouse with a scroll wheel to the laptop and wait for it to install. When you see the pointer move when you wiggle the mouse you'll know it's ready to go. Now, click any blank space on the Desktop. Next, while holding down the [Ctrl] key, scroll the mouse wheel backward and forward and watch the icons get smaller and bigger as you do so. When they are the size you want, that's it, you're done.
2) Is the computer faster when running in "Safe mode with Networking"? If so, one or more programs that you have running while running normal mode, (that don't run in Safe mode), is/are slowing your computer down. Use the process of elimination to determine the culprit(s) and remove what you don't need.
If runs at about the same "slow" speed in "Safe mode with Networking", and you have an old fashioned spinning hard drive, run the hard drive manufacturer's diagnostic utility to make sure the hard drive is okay. If it's failing, it needs to be replaced.
