You "can" install SharePoint Foundation to Windows 7 but... You have to own Professional edition.
Unfortunately, with my new Windows 7 Home Premium edition laptop I was not able to set up SharePoint Foundation. I found out that on Win 7 Home Premium IIs supports only Basic authentication and SP Foundation does not work...
I am really angry to Microsoft folks; who forgot to mention about this little issue! I can't use it on my new system, thanks guys...I owe you one :)
