well Ashu, Windows Vista is also more secure than earlier versions of the Windows® operating system. For example, Windows Vista had fewer security vulnerabilities in its first 12 months than Windows XP in its first 12 months. In the first half of 2007, Windows Defender detected 60 percent fewer malware and spyware infections on Windows Vista than on computers running Windows XP with Service Pack 2 (SP2). Windows Vista and Windows Live™ made major advancements in the way people interact with technology, connect with each other, and maintain a more secure and safe computing environment.
The release of Windows Vista SP1 enables customers to take advantage of improvements that Microsoft and its partners developed. It’s a continuation of Microsoft’s and its partners’ drive to provide the best experience possible. The goal is to address key feedback that Microsoft has received from customers without regressing application compatibility. SP1 delivers improvements and enhancements to existing features that significantly affect customers, but it does not deliver substantial new operating system features. For example, the service pack improves file-copy performance but does not include a new version of Windows Explorer. The updates in SP1 fall into three categories, which the following sections describe in more detail:
1• Quality improvements, including all previously released updates, which address reliability, security, and performance (SP1 doesn’t include updates released in the two months prior to the SP1 release, reducing the number of last-minute changes in the critical time just prior to release.)
2•Support for emerging hardware and standards, such as an Extensible Firmware Interface (EFI) and flash-based devices formatted using the Extended File Allocation Table (exFAT) file format
3•Improvements that help businesses better optimize their IT infrastructures
Windows Vista SP1 includes many performance enhancements. For example, SP1:
•
Addresses an issue in the current version of Windows Vista that makes browsing network file shares consume significant bandwidth and not perform as quickly as expected.
•
Improves the performance of copying files. In internal tests, copying files from one folder to another on the same local disk was 25 percent faster. Copying files from a remote computer that was not running Windows Vista SP1 was 45 percent faster. Because of networking improvements in SP1, copying files from a remote computer that was also running Windows Vista SP1 was as much as 50 percent faster.
1• Improves the progress estimation when copying files by using Windows Explorer so that the time estimate in the progress window appears within two seconds.
2•Improves the speed of adding files to and extracting files from compressed folders.
3• Improves the performance of power transitions (for example, resuming from hibernation and standby mode).
4• Improves the performance of domain-joined computers when operating off the domain. Before Windows Vista SP1, users would experience long delays when opening the File dialog box.
5• Improves battery life on some computers by reducing CPU use and redrawing the screen less frequently.
6• Improves the logon experience by removing the occasional 10-second delay between pressing CTRL-ALT-DELETE and the password prompt appearing.
7• Reduces the time to return to a user’s session when using the Photo screensaver.
8• Improves overall media performance by reducing many glitches.
9• In internal testing, reduces by approximately 75 percent the time to start Event Viewer.
