How can I make my computer run faster and reduce CPU usage (not counting the messy answer)?

1, regularly organize the disk fragmentation

Computer hard disk in the smallest unit is the sector, an archive usually occupy a number of sectors, whenever the hard disk is used for a long time, countless times after the new, change and delete the file, will result in a lot of intermittent sectors, and therefore non-continuous files will be more and more, the hard disk head will need to spend more time jumping to read the data, which leads to the hard disk slowdown. This causes the hard disk to slow down. In view of this, windows will have "defragmentation" appear. As long as the implementation of "organize disk fragmentation", all the non-contiguous files will be rearranged neatly, as for the implementation of time, about a week or so will be able to perform.

2. Remove scheduled tasks

Typically, when Windows XP connects to other computers, it will fully check all scheduled tasks on the other machine, and this check will keep you waiting for 30 seconds or more. The way to get rid of it is to start

a. Modify the run key in the registry to eliminate the few things you don't use often, such as Windows Messenger. enable Registry Manager: Start → Run → Regedit → Find "HKEY_CURRENT_USER\Software\ Microsoft\Windows\Current\\Insertion_Control". Microsoft\Windows\Current\Version\Run\

MSMSGS"/BACKGROUND this key value, right-click → Delete, the world is much clearer, by the way, what a couple of cfmon's are killed it.

b, modify the registry to reduce the pre-reading, reduce the progress bar waiting time, the effect is that the progress bar to run a circle on the login screen, start → Run → regedit start registry editor, find HKEY_LOCAL_MACHINESYSTEM\ Current\Control\SetControl\ Session anagerMemory\ManagementPrefetchParameters, there is a key EnablePrefetcher change its value to "1" on it. In addition to infrequent hardware replacement friends can be in the system properties of the bus device above the device type set to none (none).

3. Turn off the special effects in System Properties

This is a simple and effective way to speed things up. Click Start→Control Panel→System→Advanced→Performance→Settings→In Visual Effects, set to Adjust to Best Performance→OK. This desktop will be very similar to Win2000, I still like XP's blue window, so in the "window and button on the use of visual styles" to put a check mark, so you can see the beautiful blue interface, but also to speed up.

5, Windows XP to achieve a 1-second shutdown

The huge size of the Windows XP operating system shutdown is very slow, about 30 to 50 seconds, but according to the method we provide below to change the registry options, your Windows XP system shutdown speed will be very fast.

Find HKEY-CURRENT-USER＼Control Panel＼Desktop key and change WaitToKillAppTimeout to: 1000, which means that you will wait for only 1 second when closing the program.

Also: How to achieve fast shutdown of programs with program errors and system auto-shutdown that stops responding.

a. Change the HungAppTimeout value to: 200, which means that the program waits 0.5 seconds when there is an error.

b. Set the AutoEndTasks value to: 1 to allow the system to automatically close programs that stop responding.

6, turn off the debugger Dr. Watson

I seem to be from the win95 era began once did not use this thing, you can cancel this way: open the table, find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\Current\Version \AeDebug sub-branch, double-click on the Auto key name under it, change its "numerical data" to 0, and finally press F5 to refresh the settings to take effect, so as to cancel its operation. Along this line of thought, we can have all the debugging function of the option to cancel, such as blue screen memory.dmp, in the "My Computer → Properties → Advanced → Settings → Write debugging information → Select None" and so on.

7, speed up the startup

To speed up the startup of Windows XP. You can modify the registry to achieve the purpose, in the Registry Editor, find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters, in the right to find the EnablePrefetcher main key, change its default value of 3 to 1, so that the scroll bar scrolling time will be reduced;

9, optimize the online neighborhood

Windows XP online neighborhood in the use of the system will be searching for their own *** enjoy the directory and can be used as a network *** enjoy the printer as well as the scheduled tasks and the network of scheduled tasks. Then it will be displayed, which is obviously much slower. You can remove these features if they are not of much use to you. In the registry editor, find HKEY_LOCAL_MACHINEsofewareMicrosoftWindowsCurrent VersionExploreRemoteComputerNameSpace, delete the (printer) and {D6277990-4C6A- 11CF8D87- 00 11CF8D87- 00AA0060F5BF}(Scheduled Tasks), restart your computer and visit Online Neighborhood again, you will find it much faster.

10, automatically close the stop responding to the program

Some times, Win XP will prompt you to stop responding to a certain program, it is very annoying, by modifying the registry, we can let it close on its own, in the HKEY_CURRENT_USERControl PanelDesktop will be the value of the characters of the value is AutoEndTasks value to 1, and then log off or start up again.

11, accelerate the speed of the menu display

In order to accelerate the speed of the display of the menu, we can set up in accordance with the following method: we can find "MenuShowDelay" under HKEY_CURRENT_USERControl PanelDesktop main key, change it to "MenuShowDelay". "main key, change its value to "0" can achieve the effect of accelerating the speed of the menu display.

12, clear the memory is not used in the DLL file

In the registry's HKKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion, in the Explorer to add a project AlwaysUnloadDLL, the default value is set to 1. Note: If the default value is set to 0, this function is disabled.

13. Accelerating pre-reading improves boot speed

Windows XP pre-reading settings can improve system speed and boot speed. In accordance with the following method of modification can further capitalize on the efficiency of the CPU: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManager

MemoryManagement], in the PrefetchParameters In the right window, change the value of EnablePrefetcher as follows, such as the use of PIII 800MHz CPU or above, it is recommended to change the value to 4 or 5, otherwise it is recommended to retain the value of the data for the default value that is 3.

Four, Windows 2003

The latest Microsoft operating system is Win Server 2003, which corresponds to the server. It corresponds to the server, now there are more and more friends have upgraded to Windows 2003, after the installation, we found that some operating systems have a lot of trouble, so the function is not, that function can not open, and even listen to the song, play the game has become a problem. In fact, Server 2003 in the XP basis to strengthen the security and stability, had to close some of the workstation system. We are using Win 2003 as a workstation, of course, to re-open these services.

1, for DirectX acceleration

Just installed Windows 2003, but now found that a lot of 3D games can not run, only some traditional 2D plane game can still barely run, and the speed is very slow. It feels like Windows 2003 is fast at running PhotoShop, but why can't it run 3D games?

It's not that Windows 2003 doesn't support 3D games, it's a system setup problem. First, make sure you install your graphics drivers the right way, and then turn on DirectX acceleration, which is a basic requirement for 3D gaming, but which Microsoft has turned off by default "in order" to make Windows Server 2003 more server-oriented. However, "in order" to make Windows Server 2003 more oriented to server platform applications, Microsoft turned off its acceleration by default. Even after installing the latest DirectX 9.0, acceleration is not automatically turned on, but must be set manually. Open the DirectX Diagnostic Tool by typing "dxdiag" in the Start → Run dialog box. Then enable DirectDraw, Direct3D, and AGP texture acceleration in the Display column. In this way, Windows Server 2003 can run all kinds of 3D games. In addition, Windows Server 2003 also disables hardware acceleration by default, which you can set to Full Acceleration in the Advanced menu of the Display Properties.

2. Turn off the server wizard

After installing Win 2003, you will find "Manage your server" appears, put the bottom left corner of the "Do not show this page when you log on" check. If you can't find it when you boot up, you can go to Control Panel - Administrative Tools - Manage Your Server to find it

3. Turn on Hardware Acceleration

Right-click on your desktop and go to Properties - Settings - Advanced

This is the first time you've ever seen a computer with hardware acceleration.

4, sound acceleration

Start-Run-type dxdiag-sound, pull the "sound hardware acceleration level" to "full acceleration ".

6. Improve system performance

Right-click on the My Computer icon, go to Properties-Advanced-Performance-Settings, and adjust to the best performance.

7. Accelerate the taskbar

In addition to "Keep taskbar in front of other windows" all other removed, for the following reasons:

Auto-hide the taskbar: to avoid not finding the taskbar, and occupies the system grouped in similar

Taskbar buttons: the program is too centralized, it is difficult to find

The taskbar buttons.

Show Clock: There is no need to use the clock if there is a clock

Hide inactive icons: I don't know what applications are being used

8. Increase the speed of the desktop display

Right click on the desktop to enter the Display Properties, turn off the desktop wallpaper and screen saver, and remove all the hooks in the Appearance - Effects

9.

9, Explorer speed

In Explorer or My Computer, select Tools - Folder Options - General, select "Use windows traditional style folders".

Remove all options except "Hide protected operating system files" and "Hide extensions of known file types". In particular, turn off "Remember view settings for each folder", "Show alerts when mouse points to folders and desktop items", and "Show file size information in folder alerts". The first is to turn off and de-personalize the settings.

The third is the optimization of Explorer, which uses a "list" format to display content with minimal icons and information. In the toolbar menu, the standard buttons and links are removed, all of these functions can be realized through the shortcut keys, and it is not beneficial to leave more.

10, turn off the system desktop icons

Right-click on the desktop, select Arrange Icons, remove the hook to display desktop icons, turn off all the icons, save a lot of resources.

11, IE optimization

IE's interface optimization is basically the same as Explorer, which is to reduce the function bar as much as possible, leaving only the address bar. However, there is a lot of fun stuff in Tools - Internet Options.

General - blank page for changeable home page, open without loading any web page, fast

Advanced - multimedia, remove "Enable automatic image resizing" and just display the whole image to reduce IE's workload of IE.

Browsing, remove "Enable scheduled synchronization of offline projects", what's the point of being offline when broadband monthly subscription is so popular?

Remove "Use smooth scrolling", so that the navigation bar on the left can quickly turn pages in the normal page up/down fashion.

Remove "Notify when download is complete", it's redundant to notify when download is complete.

Remove "Show go to button in address bar", we don't have much use for go to URLs.

Remove "Automatically check for Internet Explorer updates", manual updates are always faster than automatic updates, and you don't have to keep IE constantly on the lookout for updates.

14. Optimize system startup items

Some applications are not loaded through the startup menu at startup, but run directly through the registry, for this part of the program, we can start - Run, enter msconfig, in the startup to find out the options that do not work. For example:

realsched: upgrade option for real player

elbycheck: real-time monitoring for CloneCD

qqtask: taskbar for Quicktime player

neroCheck: check for nero burning software

Adobe Gamma Loader: Gamma correction for Adobe software (Photoshop stream)
