Microsoft has issued a rare apology following complaints that Windows Vista Ultimate wasn't living up to update expectations.
Microsoft's top-of-the-range version of the operating system is a is supposed to come with lots of exclusive "extras" updates which have not arrived.
So far only four Ultimate extras are available these are BitLocker Drive Preparation, Secure Online Key Backup, an exclusive Texas Hold 'Em game, and 16 language packs for Windows multi-language user interface.
Vista Ultimate director Barry Goffe in a press release said sorry for taking so long to provide a status update to customers.
The extras still needed to fine tuning so they "meet the high quality bar required by our enthusiastic customers."
