OK, there's a windows equivalent to tcptraceroute called tracetcp.
If you're up for it, first install WinPcap from
here then tracetcp-0.99.4beta.zip (NOT source.zip) from
here. Unzip the download, copy the tracetcp.exe to c:\windows\system32 & run it from an administrator account in a terminal window.
tracetcp 80.82.140.240
