Not sure what you're going to do with that, even with a Linux install it's going to be rather slow with just about anything, As stated above Linux would be a better option over an older version of Windows but you're limited on Distros you can use.
For 1GB RAM use
Bodhi Linux
TinyCore
Damn Small Linux
Porteus ( Cinnamon and MATE desktop will use less than 512mb RAM)
LXLE
Lubuntu
Puppy Linux
Linux Lite "1GB RAM minimum better with 2GB)
More RAM allows better Distros.
This is equally as slow and I had 10 to do. They boot faster than Windows xp and Vista under Linux and you have a large amount of free software you can access via the App center. Older versions of Windows are a security risk and that is something Linux allows you to avoid since very few virus are direct at it.
