Can I create an SSL certificate on windows signed with the machine's certificate?

From MMC > Certificates I can see there's a certificate for the current machine under 'Trusted Root Certification Authorities > Certficates'. e.g. on my workstation called 'RoryWorkstation1' there's a certificate called 'RoryWorkstation1' listed along with all the normal ones like Baltimore, Microsoft Root Authority, Thawte, Verisign, etc. Can I use this machine certificate to generate an SSL certificate that I can use on the local machine? Clearly it'll only be trusted from the local machine, but for example I'll be able to make requests to https://localhost and the browser will treat that as trusted.
