From istartedsomething.com: So I guess this is what you call teaching an old dog new tricks. A couple of days ago Microsoft released a new update for Windows Vista that adds additional wireless support and functionality to the operating system through a "feature pack". Specifically it adds support for Bluetooth 2.1, a new "Unified Pairing" interface as well as "Windows Connect Now" updates and can only be installed on Vista SP1.
This is interesting to me not because any of the features above, but because up until now, the client version of Windows has never had "feature packs". We have hotfixes, security patches, service packs and rollups, but not feature packs. What are they?
Upon a little investigation (Google Search, first search), it"s apparent feature packs are quite abundant for Windows Server. To be exact, there are 16 feature packs for Windows Server 2003 which adds a variety of functionality to the server. In essence, they provide new features to an existing operating system as a standalone update. Someone smarter than me might have came to that conclusion just by looking at the name and I envy you.
