Go to Linux Mint download page: https://www.linuxmint.com/download.php
If you have a 32 bit CPU, down load the 32 bit version. However, if it is a 64 bit CPU - go with that one.
Burn it to DVD, and then boot from your DVD. This will give you the chance to play with Linux Mint. It is great for surfing, email, general use. The great thing about the DVD is that you get to play without changing your laptop. If you want to switch to Mint, you can install either as a replacement for Windows or as a dual boot option.
Trust me, you will be much happier. My 65 year old Mother-in-law loves it. She has very little technical expertise.
I dumped WinXP totally 2 months ago and couldn't be happier.
LibreOffice comes with it and is a complete replacement for MS Office. All Office doc formats work with it.
If you HAVE to have some of your programs that only run in Windows...install PlayOnLinux via the Software Manager. You can run most Windows programs on Linux with it. Plus a 10 year old can figure out how to use PlayOnLinux with no manual or training. It has a learning curve that looks like an F-16 going vertical at full throttle on a 500 foot runway.
And, Firefox comes native. Importing your current profile to the Linux machine is easy.
Can you tell I love Linux?
