Numerous improvements to the Windows Explorer, along with an updated Internet Explorer 7, Windows Media Player 11, instant search, new 3-d games and other items made it into the final version of Windows Vista. Several features of Longhorn planned that were actually shipped include the glass replicating Aero theme (which followed the Slate and Jade themes from earlier builds), along with the Windows Sidebar - although this was shipped as a standalone utility where as most builds (at least in pre-reset) shipped this as part of explorer.exe. This combined with Microsoft's trustworthy computing initiatives caused the reset. Features were being written into the OS at an alarming rate with a significant lack of QA or vision of true requirement. The reset occurred as Microsoft's development staff had lost focus on the project as a whole and what was required to be done in order to bring it to market. Development on the OS started in May 2001 and went through two unique development cycles separated by a development reset in 2004.
