Performance up to 128 MB VRAM! He has Windows XP Home! Since no security is given you can install another operating system u. Must be removed Windows XP! Mfg Peter

Is that a question? I think he will hardly pack anything other than XP.

So if you would do 512MB of RAM, then you could use Windows 10 32 bit, but I would not recommend it! I think it's more like Windows 7, but you also need a whole gigabyte of RAM.
