1. Repairing Windows XP does not need to be activated
If you need to reload Windows XP, you usually have to be reactivated. In fact, as long as you first activate, back up the WPA.dbl file in the Windows / System32 directory, you don't have to operate. After reinstalling Windows XP, you only need to copy the file to the directory above. (This fee is told! It is useless. In order to save the original text, keep it! Otherwise I will delete it) huh! ! !
2. How do you know if your Windows XP is activated?
Open the start → run, enter: OOBE / MSOOBE / A, after entering the bus, the system will pop up the window tells you whether the system is activated.
3. Let Windows XP can also engrave ISO files
Windows XP does not provide a function of direct burning ISO files, but you can download a third-party plug-in to add this feature for the system. The download address of the plugin is
http://members.home.net/alexfein/is.....rderSetup.msi.
4. Login Interface Background variable color
Open the registry editor, find [HKEY-USERS / .DEFAULT / Control Panel / Colors], change the value of Background to "0 0" (without quotation marks), so that the login background is black.
5. Fully uninstall XP
Some friends find themselves after installing Windows XP, then you can start using the Windows 98 installation CD to the DOS status, then type: format -ur can remove all XP files, and reinstall Windows 98 / Me
6. The system will save straw
When the system is suspected that the system is restarted, the changes can cause the computer to cause the fault, and the F8 key can be pressed when the system is started, select "The last correct configuration" to restore the changes made to the system.
7. Restore hardware previous drivers
When the new hardware driver is installed, the system is unstable or the hardware cannot work, simply select the "Driver Recovery" button in Device Manager to return to the previously normal system state. But you cannot recover the printer driver. 8. Automatically log in
Click Start → Run, enter "Rundll32Netplwiz.dll, Usersrundll", then cancel "User Must Enter Name and Password To Use Computer" in User Accounts, click "OK", then pop up In the dialog box, enter the username and password you want to log in to yourself.
9. Quick shutdown or restart shortcut (can be timed)
Right-click on the desktop, select New (shortcut, enter the position in the pop-up wizard): c: / windows / system32 /shutdown.exe -t 10 (where -s can be changed to -r, that is, re- Start, and -t 10 indicates a delay of 10 seconds, you can change this number according to your own needs). After making this shortcut, follow the method to specify an icon for it. This fast shutdown or restart skill will display a comparison Beautiful dialog prompts to shut down (restart), and you can add "-c" I want to shut down! "", This sentence will be displayed in the dialog box, of course, you can write freely, but pay attention to Can't exceed 127 characters.
10. Shutdown, restart as long as 1 second
If you want Windows XP to shut down instantly, you can press CTRL Alt Del, then click "Shutdown" → "Shutdown" in the pop-ups, with this, while holding down Ctrl, less than 1 second you will It is found that the system is closed, it is just between the blink. Also, if you select "Restart" in the "Shutdown" menu, you can restart quickly. 11. Looking for a lost fast boot bar
Move the mouse to the blank area of the taskbar, click Right-click to select "Properties" from the pop-up menu, select the "Task Bar" tab in the pop-up window, and then "display" "Task Bar Appearance" box "Show" Show fast start "The check box is selected," OK "is fine.
12. Batch file rename
Windows XP provides a function of batch renaming files. Select a few files in the Explorer, then press the F2 key, then rename one of these files, so all selected files will be renamed to new files Name (add incremented numbers at the end).
13. Quickly lock the computer
Right click on the desktop and select New "Shortcut" on the subsequent shortcut menu. Next step, enter the name of the shortcut in the pop-up window, click "Finish". Of course, the simplest locking computer is straight to press WINKEY L.
14. Let the double key mouse with roll page function
Double-click the "Mouse" item in the control panel, select the "Start Click Lock" item in the "Click the Lock" bar in the "Mouse Properties" dialog box. Then click the "Settings" button, set the mouse to the shortest "click Lock Settings" dialog box, click "OK" to save. Open a web page, click on the spool of the web, this function can be implemented up and down without moving the mouse not far from the web page reel. Click on the spool of the web again to close this feature.
15. Let Windows XP read English letters
Find the "Test Man" program in the "Auxiliary Tool" group, click the "Sound" button, enter the "Sound Settings" interface to set up after saving. When you point your mouse to dialog boxes, menus, and buttons, you will hear a male voice read English letters.
16. Cancel the arrow on the shortcut icon
Previously implemented this feature is more trouble, we are, just need to create a new binary value of the Link in HKEY_CURRENT_USER / Software / Microsoft / Windows / CurrentVersion / Explorer inside and amended to 00 million can be achieved.
17.Microsoft Windows XP installation essence
Install Windows XP under Windows
Insert a Windows XP disc, automatically run, display the installation interface, click "Install". If there is no automatic run, double-click the setup.exe of the optical root directory to start installing. Before restarting your computer, there are several options, you need to pay attention to: If you intend to install Windows XP to other partitions instead of C drive, you have to pay attention to the "Advanced" option, and remember to select the installation process Select a partition ", otherwise you will not be able to choose the installed partition after you will be able to select the installed partition.
Install under DOS
This situation may be a new computer, or the Windows system cannot enter. Will choose to install under DOS. The NT system is different from the 9X system. It is not like installing Windows 98 in DOS, but then loads SMARTDRV.EXE, then runs the Winnt.exe under the / i386 directory.
The specific operation method is as follows:
Suppose smartdrv.exe this file is on a disk, the optical drive is a G disk (Note: This file is on the Windows 9x CD or the Windows 9x system's Windows directory)
A: /SMARTDRV.EXE
A: / g:
g: / cd i386
g: /i386/winnt.exe
This is ok, you must remember to load smartdrv.exe. Otherwise, huh, you can't finish Windows XP.
18. Other payments ---- NTFS
About NTFS selection, if you want to install multiple operating systems, remember not to convert the C drive to NTFS. Specifically, regarding NTFS and FAT32 distinguish between FAT file systems, please see other documents, this is not fine here. If you don't know if it should be converted to NTFS, a simple way is to use FAT32, select "Do not convert". After you understand NTFS, you can use Convert.exe in command line mode to transform at any time, such as "CONVERT C: / FS: NTFS" converts the C disk to NTFS. 19. Do not load the DLL file
The browser often has some DLL files to cache a long period of time in memory, and a large part of the memory will be used by the DLL file. In order to prevent this, find the registration list as follows:
HKEY_LOCAL_MACHINESOFTWAREMICROSOFTWINDOWSCURRENTVERSIONEXPLORER This next creates a double-byte value called AlwaysunloadDll, the value is 1. If you want to remove this optimization, just set this key value to 0 (you can also delete the key). Note: This optimization takes effect after Windows reboot.
20.xp prefetcher
Windows XP comes with a service called Prefetcher. This service manages Windows startup programs initial, where specified programs can be quickly loaded in later use. PrefetCher is open by default, but its performance can also be further improved. Open the Registry Editor and find it in the registry:
HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETCONTROLSESSION ManagerMemory
ManagementPrefetchParameters, where there is a key value name EnablePrefetcher, in most cases it is 3. The recommended set value is 5 - on my machine, the work status is optimal when set to 5. You can try different values until you find the value that is best suited for your machine. You can also disable PrefetCher, just set the value to 0. However, unless it is for testing, the average will not be stupid to set it to 0.
21. Fully turn off the Windows XP file protection. This trick use
Find hkey_local_machine / software / microsoft / windows nt / currentversion / winlogon from the registry, modify the "sfcdisable" key value "ffffff9d", if you need to re-enable this feature, you can reset it to "0".
22. Memory performance optimization
There are several options in Windows XP to optimize memory performance, they are all in the registry: HKEY_LOCAL_MACHINE / SYSTEM / CURRENTCONTROLSET / CONTROL / Session Manager / Memory Management
23. Disable memory page scheduling
Under normal circumstances, XP will write a piece of memory into the hard disk, we can prevent it from doing so, let the data are kept in memory, and increase system performance. It should be noted that users with a lot of memory (more than 256M) are used to use this setting. The name of this setting is just like its function, called "disablepagingexecutive". Change it from 0 to 1 to disable memory page. 24. Lifting system cache
Change the LARGESYSTEMCACHE key value from 0 to 1, Windows XP will distribute all of the 4M memory all divided into the file system cache, which means that the XP core can run in memory and greatly improve the system speed. The remaining 4M memory is used to do disk buffer, and XP will also allocate more when needed under certain conditions. In general, this optimization will enhance system performance, but it is also possible to reduce certain applications performance. As mentioned earlier, there must be more than 256M memory, so you can activate LargeSystemCache, otherwise don't move it.
25. Input / Output Performance
This optimization is only true for Server users - it enhances the performance of the system for mass file transmission. In the default, this key value does not exist in the registry, and must build a DWORD key value to name IOPageLockLimit itself. Most people have found the best performance between 8 and 16M bytes when using this optimization, what is the value set, which value can be given to see which value can be achieved. Remember this value is calculated by bytes, so if you want to assign 12M, it is 12 * 1024 * 1024, which is 12582912. Like the previous memory optimization, only the value here is changed when your memory is greater than 256m.
26. Optimize processor secondary cache capacity
Windows XP cannot automatically detect the second-level cache capacity of the processor, you need to manually set in the registry, first open the bill (enter "regedit"), open:
HKEY_LOCAL_MACHINE / SYSTEM / CURRENTCONTROLSET / Control / Session Manager / Memory Management /
Select "SecondLevelDatacache", according to the processor settings you have, for example, PIII Coppermine / P4 Willamette is "256", Athlon XP is "384", P4 Northwood is "512"
27. For IRQ interrupt request row priority
Each of the main components of the computer has an IRQ interrupt number. Here is to achieve optimization by modifying the priority of each IRQ request. The main optimized object here is a system / CMOS real-time clock, which enhances performance through the motherboard. First, you have to determine which component you want to get higher performance, then find this hardware is using the IRQ interrupt number. How to find it? Turn on the system properties in the control panel (you can also turn it on the Windows Break hotkey combination on the keyboard). Check the Hardware tab and click the Device Manager button. Right click on the component you want to check the IRQ number, select Properties, and then click the "Resources" tab.
Here you can see the IRQ interrupt number in use (if there is no IRQ interrupt number, select another device). Keep the interrupt number, then run the registry editor regedit, find the hkey_local_machine / system / currentcontrolset / control / priorityControl location in the registration. We have to build a DWORD double-byte value called IRQ # priority (where "#" is the specific IRQ interrupt number, and then set it to 1. For example, my system CMOS real-time clock IRQ interrupt code is 8, the key name I want to build is Irq8Priority. After restarting your computer, you will find that the performance of the originally optimized components has improved. The author strongly recommends using this method to optimize the system CMOS real clock because it improves the performance of the entire motherboard. Of course, multiple IRQ interrupt numbers can be improved, but the effects doing have not been so good, and it is possible to cause system unstable. If you want to cancel this optimization, you will be OK as long as you delete the registry key value you just created. 28. Accelerate sharing
This is a great optimization. Before finding this optimization, I often wait for the window to display the shared catalog on other machines. Typically, when Windows XP is connected to other computers, all predetermined tasks on the other party are checked - this is extra, and you will make you wait for 30 seconds, it is too bad. Fortunately, it is easy to ban this process. First, find HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / Current in the registry
Version / Explorer / RemoteComputer / Namespace. In this, there should be a {D627990-4C6A-11CF-8D87 -00Aa0060F5BF} key. Just delete it, after restarting the computer, Windows no longer checks the scheduled task, and the speed is clear!
