Boot your computer Faster

Many computers take a lot of time to boot (or start ).This is due to many reasons.

Some slight changes can do wonders for your system:

1.Press start->run then type msconfig and press enter.

Go to the startup tab. Here you will see a list of startup items. These are all the programs that automatically start when you boot your PC. It is these that slow down the boot up process.

So uncheck all the unwanted items like ms-office, messengers other utilities that u may not need at startup). Don't uncheck your antivirus software.

Restart your Pc to and see for yourself, your pc will now boot faster....

2.A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option is enabled, but on some systems it is not, so below is the information on how to turn it on:

Go to Start Menu and Click Run
Type in regedit then click ok
Find "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOpt imizeFunction"
Select "Enable" from the list on the right
Right on it and select "Modify"
Change the value to Y .
Reboot your Pc and see the change yourself.

3.SPEED UP BOOT BY DISABLING UNUSED PORTS.!!

You may have tried many tweaks like modifying windows XP start-up applications, prefetches, unload DLLs method, etc. And yes those methods do work for me.
I have just accidentally found out another way to give you an extra boost in windows XP's boot performance. This is done by disabling your unused devices in
Device Manager. for example, if you don't have input devices that are connected to one of your USB's or COM ports, disabling them will give you an extra performance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart

IMPROVE XP SPEED

This tweak reduces the time XP waits before automatically closing any running programs when you give it the command to shutdown.
Go to ‘Start’ then select ‘Run’
Type 'Regedit' and click ok
Find 'HKEY_CURRENT_USER\Control Panel\Desktop\'
Select 'WaitToKillAppTimeout'
Right click and select 'Modify'
Change the value to '1000'

Click 'OK'

Now select 'HungAppTimeout'
Right click and select 'Modify'
Change the value to '1000'

Click 'OK'

Now find 'HKEY_USERS\.DEFAULT\Control Panel\Desktop'
Select 'WaitToKillAppTimeout'
Right click and select 'Modify'

Change the value to '1000'

Click 'OK'

Now find 'HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\'
Select 'WaitToKillServiceTimeout'
Right click and select 'Modify'
Change the value to '1000'

Click 'OK'

VISTA REQUIREMENTS

According to Microsoft corp, computers capable of running Windows Vista are classified as Vista Capable and Vista Premium Ready.

A Vista Capable or equivalent PC needs to have at minimum an 800 MHz processor, 512 MB RAM and a DirectX 9 class graphics card. A computer that meets these requirements will be capable of running all editions of Windows Vista although some of the special features and high end graphics options may require additional or more advanced hardware.

Hardware Requirements
A Vista Premium Ready PC will take advantage of Vista's "high-end" features but will need at least a 1.0 GHz processor, 1 GB main memory, and an Aero-compatible graphics card with at least 128 MB graphics memory and supporting the new Windows Display Driver Model. The company also offers Windows Vista Upgrade Advisor from its website to determine the ability of a PC to run Vista in its various guises. The utility runs on Windows XP (with Service Pack 2) and Windows Vista.
Microsoft lists some Vista capable hardware on their website. The "Windows Vista Premium Ready" laptops they specify have Intel Core 2 Duo T5500 or above CPUs and 1 GB memory.

Windows Vista's "Basic" and "Classic" interfaces will work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA GeForce FX family and later, the ATI Radeon 9500 and later, Intel's GMA 950 integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported. Though some XGI Technology Volari chips were DirectX 9 (including the Volari V3XT which was available in PCI cards), with XGI's exit from the graphics card business it appears none of its chips are supported as of Vista Beta 2. A PCI Express (PCIe) video card is not a requirement for Windows Aero, but Microsoft recommends PCIe video over an AGP device due to the interface's greater bandwidth. There are some PCI cards available that are compatible with Windows Vista as well.
