Since windows vista is released in the market for home and business world , windows vista was not able to capture the market due to some of the some of the disadvantages/ Drawbacks associated with this .

1. Requirements high,

Windows vista consumes a lot more resources than its predecessor windows XP. For vista Aero to work, you need to invest something more than what you would have expected to invest before. The graphics card requirement is quite high. The graphics card must be of DirectX 10 supported. The required minimum graphics memory on the graphics card is 128 MB. For better performance, graphics memory must be of 256 MB. The minimum hard disk space required is 20 GB for installation of Windows Vista. Processor speed is also expected to be high for Aero to work smoothly without causing any hiccups. The memory requirement for Windows Vista system is high. The system will work smoothly when one has got RAM of about 2 GB installed. Totally, I would like to say that, Windows vista eats up lot of resources, than its predecessor, the Windows XP.

2. Issue with the Drivers compatibility :

One of the common issue with the windows vista is that the ,device drivers compatible for windows vista are not released by all the manufactures of the hardwares ,so many of the device such as graphics card and webcam had compatilbility issue with the windows , before purchasing any new device we need to check out for Vista compatible or Vista ready logo, which is put up on the device.

3. Regarding price :

The price for Windows Vista editions are also high. Ordinary users cannot thus, have a look into all the features of Vista, which is only available in the Ultimate Edition. Microsoft seems to be not so interested in country wise markets. The prices are set according to the US market. However these prices are on higher side for developing asian countries. Microsoft should set the price of Vista as per the market.

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 .

and now one more effort from microsoft removing all these issues , microsoft is ready to release SP2 for windows vista ,On Wednesday, Microsoft announced that Windows VistaSP2 is RTM (Released to Manufacturing), which means Service Pack 2 (SP2) for Windows Vista will soon 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 .

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 use of windows vista Sp2 , after the release of windows 7 having some of the enhanced features .
