Games like Minesweeper or FreeCell received a much needed visual update with improved graphics and audio. This was something that Microsoft has not done since Windows 95. Looking back most games that came preinstalled in Microsoft operating systems looked the same over the years. Minesweeper for one did not look that much different in Windows 95 and some people say that even experienced users would be hard pressed to tell the differences.

This has changed with Windows Vista. That has not been the only change though game wise. Microsoft developed new games that were included with Windows Vista. Looking back anyone will notice that previous operating systems were all shipping with the same games.

The most popular games of previous systems have been ported to Windows Vista. Nine games are preinstalled in Windows Vista on all editions of the operating system. Five games of nine are known from previous Windows operating systems. Included are the popular card games Hearts, FreeCell, Solitaire, Spider Solitaire and the game Minesweeper.

Additionally four new games are included that cater to a wide variety of tasks: Chess Titans, Mahjong Titans, Purple Place and Inkball are as different as possible.

Chess Titans and Mahjong Titans are conversions of the two popular boardgames Chess and Mahjong. Purple Place was designed for a younger audience and Inkball which is probably the only fail in the list of games since it was designed for Tablet users and is not that playable with a mouse in advanced levels.

Two additional games have been released for Windows Vista Ultimate users. Windows Vista Ultimate Hold ‘Em is a conversion of the popular Texas Hold ‘Em poker game which is probably the most popular card game in the world thanks to the Poker craze.

The second game is called Tinker. A strategic game where the player has to guide a robot from start to exit avoiding obstacles in the way. It ships with 60 levels and does come with a level editor and download levels created by other players.

Microsoft created an interesting variety of games for Windows Vista users that can all be accessed in the excellent Windows Vista Game Explorer which acts as a central game hub on the system.

Windows Vista is different from XP starting by the fact the PBR code written by Windows Vista no longer looks for Ntldr. The new boot loader in Windows Vista is Bootmgr. This component loads the Boot Configuration Database (BCD), which in turn loads an OS loader boot application (Winload.exe, in the case of Windows Vista). Finally, the OS loader application is responsible for initializing the kernel. This process is illustrated below.

You can think of this change in two elements:

The two key actions performed by Ntldr in previous Windows versions have been divided between two components:

1. Bootmgr reads the boot configuration, including device and path locations.

2. WindowsSystem32Winload.exe initializes the kernel.

The boot configuration stored by Boot.ini in previous Windows versions is now stored in an extensible database, BootBCD, the Boot Configuration Database (BCD).

These changes are significant because of the impact they have:

1. The boot process can be extended to support other applications, such as other operating systems or other versions of the OS.

2. Only nonversion-specific components are stored in the root of the active partition. This means that theoretically Windows Vista could be installed on a machine running some future Windows version with the same boot structure, and it would not break the boot process for that future version. With legacy Windows, installing an older Windows version last causes the newer version to fail on start-up. This is due to version-specific code improvements in Ntldr.

3. Tool-oriented boot entries can be supported to offer maintenance options on boot when a previous start-up failed. In the past, Windows supported an menu provided by a target operating system. This new structure can make tools available earlier during the boot process, meaning that they are available even if all OS-specific boot entries are damaged. The Windows Memory Diagnostic tool is provided in the boot menu in this way.

BCD Store

The Boot Configuration Data (BCD) store contains boot configuration parameters and controls how the operating system is started in Microsoft Windows Vista operating system. These parameters were previously in the Boot.ini file in BIOS-based operating systems or in the nonvolatile RAM (NVRAM) entries in Extensible Firmware Interface-based operating systems. You can use the Bcdedit.exe command line tool to affect the Windows code which runs in the pre-operating system environment by adding, deleting, editing, and appending entries in the BCD store. Bcdedit.exe is located in the WindowsSystem32 directory of the Windows Vista partition.

The BCD is a database used by Bootmgr. It contains the functions of Boot.ini and is located in the {ActivePartition}boot folder

Bcdedit.exe

You can use Bcdedit.exe to modify the Windows code which runs in the pre-operating system environment by adding, deleting, editing, and appending entries in the BCD store. Bcdedit.exe is located in the WindowsSystem32 directory of the Windows Vista partition.

Boot.ini Compared to BCD

BCD eliminates the need for Boot.ini in Windows Vista, although Boot.ini is still present on dual-boot systems for backwards compatibility. Because the BCD boots to the boot environment first instead of Ntldr, the location of Ntldr is not verified unless a legacy operating system is chosen.

Configuration Tools

The BCD store can be modified or repaired using several tools:

System Properties in Control Panel

SystemPropertiesAdvanced.exe

Msconfig

Windows Recovery Environment (WinRE) Startup Repair

Bcdedit.exe

Bootrec.exe

Most of these tools enable you to perform simple tasks, such as setting a boot menu timeout, setting a default operating system, or configuring boot options such as /SOS and /SAFEBOOT. Others are repair-oriented tools; Startup Repair and Bootrec.exe, in particular, provide automated mechanisms for fixing problems in the BCD.

Bcdedit.exe is the main tool for detailed BCD store modifications. You can use Bcdedit to change Bootmgr options; add boot, delete, and edit boot entries; import and export the BCD store; and create a new store if it becomes significantly damaged. Bcdedit.exe is located in the WindowsSystem32 directory of the Windows Vista partition and is also available in WinRE.

BCD Store Location

The BCD store is a registry hive, stored as BootBCD on the active partition. This hive is loaded but hidden from view in Regedit.exe within Windows Vista. The store is loaded to the following registry location: HKLMBCD00000000.

You can also view the store manually in WinRE by loading the hive from the Boot folder. To obtain a copy of the hive on a running system, use the Bcdedit /export filename command to export a hive file for offline examination. This command exports the BCD store to a file called filename in the current directory.

Related Components

Msconfig

Msconfig is the preferred PSS UI tool for managing boot settings. The tool supports BCD and allows the user to enumerate all BCD objects in the system store. It allows certain elements to be altered for each OS object, including debug settings, safe mode settings, and other popular PSS options. It cannot be used with the WinRE console; Bcdedit needs to be used in these cases.

Bcdedit.exe

Bcdedit.exe is a command line tool that can be used to manage BCD settings. In summary, Bcdedit.exe is a replacement for Bootcfg.exe. However, it is enhanced for better scripting and to expose some of the more powerful features of BCD that bootcfg.exe did not expose for manipulating Boot.ini. Bcdedit.exe is designed to work on previous operating systems and in recovery environments.
