My video will teach you how to make a custom user account picture in MS Paint for Windows 7 and how you can change your user account picture.
All you need to do is set your image size to 128 x 128 pixels by pressing the re-size button and picking pixels, and type in 128 x 128 pixels for both your width and height. When you are done drawing your avatar, you need to save it as a PNG or BMP image file. Lastly, right click on your desktop and pick personalize. From the left sidebar, click “change your account picture” link in personalization window. Lastly, click on “Browse for more pictures…” link at the bottum left of the window, and click on your picture.
This tutorial also works for Vista.
