Oppose So how do we define the time when it is being officially being pushed out Microsoft has officially announced the rebranding of Windows Live ID to Microsoft account Ref As you mentioned some products such as Windows 8 and Visual Studio 2012 already refers to it as Microsoft account Some service will gradually transition to the new name Whilst some other products may never transition do we really expect Microsoft to update mentions of Windows Live ID in Windows 7 There will never be a fine line to say yes Microsoft account has been officially pushed out today In such case I believe that the official announcement is sufficient Furthermore Windows Live ID already redirects to Microsoft account and hence readers will have no issue reaching here
