The library could be a good place to install Windows 7 and Internet Explorer to have a central place for people to go to, for sign up on the Healthcare site.
Some libraries might still be using a compatible system like Windows 7.
Check your library and ask what they are running, or, if Windows 7 can be installed to help people log onto the government website.
Use Explorer 9. I think 10 will work too.
