Windows 2000 has none of the algorithms used by TLS 1.2, so even if you install a modern browser which can do TLS 1.2 on a Windows 2000 machine, it doesn't have the maths to do the encryption. Windows XP can do TLS 1.2 with Service Pack 3 or 4 installed.
== Secure Hashing Algorithms ==
As a generic approach to writing an encryption algorithm, SHA-1 gives rise to most of the SSL through TLS 1.0 cipher suites.
TLS 1.2 needed a more complicated algorithm which is called SHA-256, or SHA-2 for short.
