Tweak Windows For Performance

Follow the guide on how to debloat and optimize Windows 7 for better performance.

Use Pale Moon Optimized For Atom

Download Pale Moon

Pale Moon is a free and open-source fork of the popular Firefox browser available for Linux, Windows, and Android. This browser is relatively faster than vanilla Firefox or Chrome on this setup.

This version of Pale Moon is optimized specifically for use on Intel Atom™ processors and compatible with the Windows XP and Server 2003 operating systems.
Many low-powered netbooks and laptops are equipped with this processor, and using a build of Pale Moon specifically optimized for this processor will reduce power consumption and increase speed of the browser for these systems.

Install Modded Graphic Drivers

Download Chell Drivers

These drivers provide a decent boost in graphical programs but obviously you won't be playing any recent AAA game with this kind of hardware as it is very limited.

League of Legends - Lowest settings: 10-12 FPS

Use GMABooster

This little program will boost the clock of the graphics chip GMA 950 up to 400 Mhz (2.4x boost), giving you a slight FPS increase.
