How to reduce windows vista boot up time?

After installing Windows vista on my notebook i noticed that it was taking much booting time compared to its earlier version. but still there are some system hack through which we can reduce booting time in windows vista.

1. HACKING THE BIOS


CHANGING THE BOOT ORDER some times the default boot order is set to boot from CD-DVD drive which means your BIOS search for any bootable media other than primary hard disk which takes few milliseconds to boot up. Set your boot priority to Hard Disk.
Press F2, Delete, or the correct key for your specific system on the POST screen (or the screen that displays the computer manufacturer's logo) to enter the BIOS setup screen.

Using Quick Boot  ture of BIOS ,during the startup of system BIOS checks for different hardware and amount of system memory.BIOS keeps track that all the hardware are working properly. Besides this it perform various memory checks which takes a lot of time because more system memory will need more time to be tested. Today most of the BIOS provide quick boot feature which disables the memory check or perform some specific checks.


2.Hacking Windows Boot manager
 Lowering OS Timeout values
If you have multiple operating systems installed on your computer and the Windows Boot Manager is installed, the default selection timeout is often way too high. It is much better to set a lower timeout so that if you do not make a selection, it quickly reverts to the default OS, making your boot time much faster.

Using Device Manager to disable hardware

Getting rid of extra hardware with Device Manager is an easy way to speed up your boot. Follow these steps to disable your extra hardware devices:

1. Click the Start menu, type devmgmt.msc in the Search box, and press Enter.
2. After the Device Manager loads, you can browse through your devices that are connected and currently running or disabled by browsing though the device type sections. To disable a device, right-click the device name, and then select Disable.
3. To re-enable a device, right-click the device name and select Disable.
   
   

   Which hardware devices should you disable?

   Each user uses (or doesn't use) devices differently depending on the system setup. Nonetheless, some classes of devices are more commonly disabled than others. Knowing which ones will help you make your decision as to which devices you should disable. The following classes of devices are frequently disabled:
4. Network adapters: Especially on notebook computers, there is often more than one network device. Disabling the network devices that you do not use will definitely save you some booting time.
5. FireWire: If you have 1394 connections, otherwise known as FireWire, you might consider disabling them. Unless you are using your FireWire port to connect your digital video recorder to your computer, or have other external FireWire devices, you have no need to have this device enabled.
6. Biometrics: Some of the latest computer hardware includes biometric sensor equipment such as a fingerprint scanner. If you do not use these security features, you can save time by disabling these devices, too.
7. Modems: Do you have a broadband connection? If so, consider disabling your modem. If you rarely use it, why not disable it? If you ever need to use it again, just re-enable it.
8. TPM security chips: Does your computer have a Trusted Platform Module (TPM)? These chips are typically used as a secure place to store an encryption key that would be used for something such as hard drive encryption. If you are not using any of these advanced security features of Windows Vista, disable these devices, too.
9. Multimedia devices: Your computer has lots of multimedia devices. Take a look at the "Sound, video, and game controllers" section in Device Manager. You will find a lot of device drivers that are loaded during your boot. Some are used by all users, but you will find a few that you do not use. For example, I do not use my game port or my MIDI device, so I disabled both of those.
10. PCMCIA cards: If you are a laptop user, consider disabling your PCMCIA card controller located under "PCMCIA adapters." The PCMCIA (Personal Computer Memory Card International Association) slot is a special expansion slot that is rarely used today on laptops except for wireless and wired network cards and card reader attachments for compact flash and other solid-state memory cards. Most laptops now have built-in network adapters, and some even have built-in wireless adapters. If you do not use your PCMCIA adapter, it is yet another device you can safely disable.

Caution

Do not disable any hardware devices located under the Disk Drives, Computer, Display Adapters, IDE Disk Controllers, and the System sections (except for the system speaker). These hardware devices are critical to the operation of your system.

Removing extra fonts for speed

Windows Vista has more than 200 different fonts and variations that it loads for use when the system boots up. Of these 200-plus fonts, only a handful are used on a regular basis. Every single font that Windows loads increases the amount of time the operating system takes to boot. If you are like me and have installed one of those font CDs that add hundreds of additional fonts to your system, you will notice that your computer does not boot up as fast as it once did. Simply put, systems with a lot of fonts will take more time to load because the system has to load and index each font. Thankfully, there is a very simple answer to this: Just remove the fonts that you do not use from your font directory.

You can go about removing the unneeded fonts from your font directory in a number of different ways. The best way is to move the unused fonts to a separate folder on your system so that in the event that you ever want to use one of those extra fonts again, you just have to copy it back to the Fonts folder.

Caution

When you remove fonts from your computer, you will no longer be able to use them in any software application, including Adobe Photoshop, Microsoft Word, and Excel.

 

Disabling unneeded services

A service is a software application that runs continuously in the background while your computer is on. The Windows operating system has numerous services that run in the background that provide basic functions to the system. Network connectivity, visual support, and external device connectivity such as printer services are all examples of the types of services that the Windows services provide. Each service that is running in the background takes up system resources, such as memory and CPU time. Also, during the booting of the operating system, the service has to be loaded. On most computers, there are nearly 20 services that are loaded upon startup. Of these 20 services, only a handful are system-critical services; all the others can be disabled.

To disable a service, you first need to know more about what the services in Windows Vista do. Table will help you understand what the most common services are, what they do, and whether they can be disabled. The services marked in bold are started by default in Windows Vista.

Optimizing the location of the boot files

The speed at which your files are read depends on your physical hard drive access speed and where the files are located in your hard drive. To increase the speed of your boot, you want to have the files used to boot your computer in a location that will allow the fastest read speed possible.

Windows Vista does a good job of this from a fresh install, but over time as your hard drive fills up and you make changes to the configuration of Windows, some of your boot files can become scattered all over inside the hard drive, resulting in a slower possible read speed. In addition, adding new applications and new hardware can contribute to this even further. Over time, your original boot optimization fades away as your internal hard drive data makeup changes.

Using Windows Vista Disk Defragmenter

Starting with Windows XP and continuing in Windows Vista, the Prefetcher service will automatically optimize the location of the boot files in your hard drive using Windows Disk Defragmenter. However, this occurs only after a certain number of boots and when it gets around to it (because it runs only when your computer is idle).

Microsoft has a talented team working on the Prefetcher service that even took into consideration your system boot changes. For example, you might install an updated device driver or add new hardware. To solve this problem, the systems will re-defragment the boot files every three days.

Tip

Windows keeps track of the last time that it has optimized the boot file so that it can calculate how often it should run the boot defrag. If you are interesting in finding when the last time was that the boot defrag was run, open regedit and navigate to HKEY_LOCAL_MACHINE\ SOFTWARE\Microsoft\Windows NT\CurrentVersion\Prefetcher, and then look for the key named LastDiskLayoutTimeString.

An operating system that takes care of itself? Yes, Windows is getting smarter and smarter. However, there is still one problem: There is no possible way to directly initiate a boot defrag. The only way is to leave your computer on for a little while without using it at all. If you are impatient and do not want to wait, I have a solution for you.

As I mentioned earlier, the system will initiate the boot defrag only when the system is idle. Typing in a command that will start the boot is not possible. However, you can tell your computer, even when it is not idle, to process the idle tasks. This will indirectly start the boot defrag. Because the boot defrag is most likely not the only idle task waiting to be run, other processes will be run, too, which can cause your computer to appear to be doing a lot of hard work-from a few minutes up to half an hour-as it completes all tasks. During this time, your computer should not be used for any intensive activities such as playing games. If you try to use your computer while the idle tasks are being processed, you will notice slow performance until the tasks are completed.

Perform the following steps to process all idle tasks:

1. Click the Start button, type cmd in the Search box, and press Enter.
2. When the command prompt opens, type Rundll32.exe advapi32.dll, ProcessIdleTasks and press Enter. Your computer will now work on the tasks.

Performing these steps will allow your system to defrag the boot files; however, the boot defrag is done every three days. Processing the idle tasks more frequently will do nothing to help you boot because the boot defrag will not be on your idle tasks lists all the time.

Using other third-party boot defrag programs

The built-in boot defragmenter is pretty darn good. However, a few third-party defrag utilities think they can do it better. To name a couple, Diskeeper and O&O Defrag both offer boot defragmentation support. Third-party defrag utilities often use different defrag algorithms that they believe work best. In the , I show you how to use Diskeeper to run a boot defrag.

Boot-time system defrag with Diskeeper

To defragment system files, and other files that are normally in use, the defragmentation must be run during the early stages of system boot. This will allow the defrag program to have full access to all files so that it can place them together on the disk. One programs that allows this to be done is called Diskeeper, which was developed by Executive Software. A trial copy of Diskeeper 2007 can be found on Executive Software's Web site (http://www.Diskeeper.com). If you have not already installed Diskeeper, do so now before proceeding any further. After you have it downloaded and installed, follow these steps:

1. Click the Start Button, type Diskeeper, and press Enter.
2. When Diskeeper 2007 loads, click Action, expand Volume Properties, and select Boot-Time Defragmentation.
3. Boot-Time Defrag Properties will now load. Select the drive where your OS is installed, usually C. You can also select multiple drives by holding down Ctrl and clicking them. This is useful if you may have applications that are stored on a drive different than where your OS is stored.
4. Under the Boot Time Defragmentation section, select Enable boot-time defragmentation to run on the selected volumes, as shown in 
   
   
5. Check Defragment the Master File Table (MFT), too.
6. Press OK and reboot your computer.

Caution

If you have enabled the alternate book screen, as shown in, you may have issues with running a boot-time defrag with Diskeeper. In current versions, the defrag status will be hidden from view behind the alternate boot screen. If you want to see the status of the defrag, disable the alternate boot screen, as shown in.

When you reboot your computer, you will notice that instead of loading into Windows all the way, Diskeeper will run in a pre-Windows environment so that it can have full access to your disks before any system files load. Depending on the size of your hard drive, the defragmentation process can take hours. It is best to do a boot-time defrag overnight
