DETAILS OF WINDOWS VISTA OS

Microsoft published the new product name Vista for this new Windows Version on an event in the USA/Atlanta on 21-07-2005. This Windows Version was known under the development name Longhorn before. The installation of Vista is based on WIM (Windows Imaging format), a file-based Image Format. It compresses the contained files and can be used for the installation on several platforms from the same Image. The image on the DVD contains a pre-installation of the system directories of Windows in the Windows Imaging (.WIM) file and adapts to the hardware configuration. With the User State Migration Toolkit the user defined settings can be imported of Windows 2000 and Windows XP. An advantage of WIM images is the easy integration of new drivers and updates, the LZX compression provides the smallest file size and XPress compression the fastest compression. The installation DVD of Windows Vista already contains about 16,000 drivers, the Windows update offers further 14,000 drivers for supported hardware. There is no licence key during the Windows Vista installation necessary, in this case it start with a 30 days trial license. After this time period the activation of the operating system is inevitably with the Internet Explorer, after the start-up Windows opens only this window for activation.

Developer take advance from the new graphic interface WPF (Windows Presentation Foundation) for the component-based development of 2D and 3D applications, WPF was designed under the code name Avalon. This framework supports the use of vector graphic for better scaling of applications on the display screen.

For better Security Microsoft has integrated useful functions. The automatic update of the operating system provides the installation of new patches. When required the function UAC (User Account Control) asks the user whether it shall unlock unlimited user rights for the execution of a program. InfoCards makes the automated log-on and register of login informations for web pages possible. Windows Defender extends Windows by an spyware/malware protection, the Windows Firewall monitors connections which are incoming and outgoing.

The performance is for a shorter reactivation time of Windows with the active programmes after a cold start of the PC improved by Windows SuperFetch. Windows ReadyBoost provides an additional working memory on USB flash devices and can be combined with SuperFetch. The USB flash storage has much faster access times than hard disks.

Preinstalled Programs by Microsoft were updated. The Internet Explorer 7 contains a Phishing Filter opposite to the previous version and supports Tabbed Browsing. The navigation in the Windows Explorer was revised, the address bar is equipped with single-line option fields displays for faster navigation in the directories on the file system. The search after files is possible with the use of many filters. Outlook Express was renamed in Windows Mayl and got version 7.0 now.
