Optimize Windows Vista for Better Performance
When you buy a new computer at that time you get the best performance from your computer but over a period of time you install anti-virus, anti-spyware and many other programs. Gradually your computer behaving very poorly. Whatever the cause, there are a lot of ways to help speed up Windows and make your PC work better—even without upgrading your hardware. Here are some tips to help you optimize Windows Vista for faster performance.
Delete unused programs:It’s a good idea to uninstalled programs you don’t have used over a long period of time. Many computer manufacturers load a lot of free utility software’s in computer and these software’s use your precious processing power, memory and disk space.
Limit startup load programs: Many software programs are designed in such way that they start when windows starts and run in background. Automatically loaded programs add an icon in system tray so it’s easy to figure out which programs are loaded when windows started. Automatically loaded programs can also be removed form Windows Defender.
Software Explorer of Windows Defender will help to you to enable or disable startup programs.

Clean and Defragment Hard Drive: Disk Defragmenter rearranges fragmented data on hard drive and this result in better performance of hard drive. While browsing the internet and using computer programs you get a lot of temporary file it’s better to delete all those file. For deleting these file you can use disk cleanup.
Disable Unwanted Service: Windows has more then 100 running in background and these service starts when windows starts and stop when windows get shutdown. Some secure Microsoft services cannot be disabled, but most others can be. Many software companies also install their own services, some of which you can disable to conserve memory and processor power. Service that you won’t require stops those services or make them as “start manually”.
Check Viruses and Spyware’s: If your computer running slower then the normal computer performance, programs are automatically starting, hard drive is constantly working and unexpected pop-up messages are coming then it might be that your computer is infected with some virus. Before all these problems start worrying you checks your computer for viruses regularly. Spyware is a type of program that is installed, usually without your knowledge, to watch your activity on the Internet. You can check for spyware with Windows Defender or other anti-spyware programs. The best way to deal with viruses is to prevent them in the first place. Always run antivirus software and keep it up to date. Even if you take such precautions, however, it’s possible for your PC to become infected.
Check Computer Performance: If all of the above tips won’t work for then check your computer performance. Windows provides a way to check and rate your PC’s speed with a tool called the Windows Experience Index. The Windows Experience Index rates your computer on five key components and gives you a number for each, as well as an overall base score. This base score is only as good as your worst-performing component sub-score. Base scores currently range from 1 to 5.9. (There is no score yet of 6.0 or higher, although Microsoft plans to raise the ratings in the future as hardware improves.) If your PC is rated lower than 2 or 3, it might be time to consider a new PC, depending on what tasks you want to do with your computer.
