Windows Vista Service Pack 2 is an important update that includes support for new types of hardware and emerging hardware standards. You will find information about the specific changes and improvements included in SP2 below.
Even after the release of SP1 for the winodws vista all these drawbacks are not removed compatibility , one of the major concern for the windows vista user is regarding drivers compatibility , many of the drivers for the devices are not compatibile for the Windows Vista .
Microsoft has released SP2 for Windows vVsta ,On Wednesday, Microsoft announced that Windows VistaSP2 is RTM (Released to Manufacturing), which means Service Pack 2 (SP2) for Windows Vista will be available for download.
While Vista SP1 was a comprehensive updates that fixed the now well-known performance- and device-driver compatibility issues that early Vista users faced, Vista SP2 fine-tunes performance and adds support for new types of hardware and emerging standards.
We can download SP 2 from Windows Update and If you have SP1 already you'll only have to download 43MB of files (60MB for 64-bit); the full installer is anywhere from 302MB to 622MB depending on the languages and whether it's 64-bit).
You'll get some of that space back; the Service Pack Clean-up tool removes files from RTM and SP1 that SP2 replaces. Expect to have to install an update and reboot first; this update installs a servicing stack that makes the SP2 installation faster and handles removing updates and optional features once it is installed. If you tried the beta of SP2, you have to uninstall it first to get the release version.
This speeds up both indexing and search, it indexes shared folders and (if you want) encrypted files and it's more reliable (Microsoft says it fixes over 85 per cent of reported crashes), but you can download it separately.
Some of the key features of the windows vista SP2 are the followings :--
1. Windows Search 4.0 for faster and improved relevancy in searches.
2. Bluetooth 2.1 Feature Pack supporting the most recent specification for Bluetooth Technology.
3. Ability to record data on to Blu-Ray media natively in Windows Vista.
4. Adds Windows Connect Now (WCN) to simplify Wi-Fi Configuration.
5. Windows Vista SP2 enables the exFAT file system to support UTC timestamps, which allows correct file synchronization across time zones.
But its a big question mark on windows vista Sp2 success after the release of windows 7 which will have some enhanced features.
