Connect a Win 8 tablet to a Vista laptop

Hi

I've been playing with Win 8 for a while now and love it but I'd like to try and share stuff on my old laptop with it.

I can connect my Vista laptop to my tablet, because I can view devices on the network, but Win 8 uses Homegroups which I believe Vista doesn't.

I've never use Win 7 so have no experience.

Can anyone offer any assistance?

Cheers in advance

Chris
