Using a SSD to Cache

I got a new laptop that has a 1GB Hard Disk and a 24 GB SSD although Windows says it's 24.9 GB. Can I use my SSD to cache some windows files? Ideally to make windows boot faster or some performance increase. I run Windows 8 so I don't think there would be enough room to install windows on my SSD. Really I'm just trying to figure out what to do with all this free space. Any ideas? Thanks for any tips.

Windows doesn't support SSD caching AFAIK. Except for hardware SSD caching but that's essentially just a normal dirve for the OS so that doesn't count. But I'm pretty sure that 24GB should be enough for a Windows install.
