Version one of the Microsoft “immputable” security laws can be found here: http://technet.microsoft.com/en-us/library/cc722487.aspx.
Currently Microsoft made some amendments and published version 2 of their immutable lows. And the new version can be found on http://technet.microsoft.com/en-us/library/hh278941.aspx.

So those laws apparently were not so immutable. I started wondering what else from the Microsoft category “immutable” is susceptible to changes 🙂 – hope not the .net immutable 😉
