XP operating system optimization skills

registry, as the core of the Windows operating system, we have not used a lot of functions. Have you ever thought about speeding up your system by modifying the registry or deleting some unwanted features? The registry, as the core of the Windows operating system, we have not used a lot of functions. Have you ever thought about speeding up the system by modifying the registry or removing some unwanted features? Please see the tips for improving the Windows XP system by modifying the registry.

1. The new party running when the program starts up fa

Click “Run” in the “Start” menu, enter “Regedit” in the “Run” dialog box to open the registry. editor. Expand the registry to HKEY_CURRENT_USER\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Windows, create a new string value here, and right click on the primary key "Windows", select "New" → "String" from the pop-up menu. Value", the string value is named "load". Then, double-click "load" and change its key value in the pop-up window to the program path that you want to run automatically. Note that the short file name of the file should be used, ie "C:\\Program Files" should be written as "C:\\Progra~1".

2, speed up the system boot and shutdown speed

Windows XP system "start" -> "run" -> type "Regedit" --> "HKEY_CURRENT_USER" - -> "Control Panel"--> "Desktop", change the value data of the string value "HungAppTimeout" to "200", change the value data of the string value "WaitToKillAppTimeout" to 1000. Also in "HKEY_LOCAL_MACHINE" --> "System"--> "CurrentControlSet"--> "Control", change the value data of the string value "HungAppTimeout" to "200", change the value data of the string value "WaitToKillServiceTimeout" to 1000 .

3, improve the response speed of XP

Find the HKEY_CURRENT_USERControl PanelDesktop subkey in the Windows XP registry, modify the HungAppTimeout value. The HungAppTimeout value indicates the time limit for the system to manually end the suspended task. The default value is 5000 and the type is REG_SZ. Decreasing the value can reduce the response delay of the system under certain special conditions. For example, you can set the value to 1000. . When adjusting this key value, you should be aware that if some software runs slowly on your system, setting the key value too small may cause XP to mistakenly believe that the running software has been suspended. If this happens, you can gradually increase the HungAppTimeout value by 1000 each time until XP no longer mistakes the running software for "stopping response."

4, clear the DLL file not used in memory

In the "start" --> "run" -> type "Regedit" --> "HKKEY_LOCAL_MACHINE" -- > "SOFTWARE"--> "Microsoft"--> "Windows"--> "CurrentVersion", add an item "AlwaysUnloadDLL" in "Explorer", the default value is set to 1. Note: If the default value is set to “0”, this function is disabled.

5, change the "My Computer" and "My Documents" location

Win2000 version of the Windows operating system "My Computer" chart is placed in "My Documents "On top of it, the Win2000 and later operating systems are just the opposite. In Windows XP, we can modify the registry to put the "My Computer" icon on the "My Documents", the specific steps are as follows: find HKEY_CLASSES_ROOT\\CLSID\\{450D8FBA-AD25-11D0- in the registry 98A8-0800361B1103}, then create a new Dword value "SortOrderIndex" and modify its key value to "54" (hexadecimal). If you want to put "My Documents" in the first place, you only need to modify the key value of "SortOrderIndex" to 48 (hexadecimal).

6, prohibit IE download files

Public computers sometimes need to prohibit downloading file functions, although some management software can do this, but installing and debugging such software is too much trouble . In fact, a slight modification in the registry can meet everyone's requirements. Open the registry editor, find HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings\\Zones\\3, then find the DWORD value of 1803 on the right and change its key value to 3. Restart IE to see if you can download it. If you want to cancel the restriction, you only need to restore the DWORD value to 0.

7, let IE support multi-threaded download

In general, everyone uses multi-threaded download software such as Flashget to download files, in fact, IE can also support multi-threaded download, but Microsoft will This feature is hidden. We can dig it out and use it. Open the registry editor and create a new double-byte value item "MaxConnectionsPerServer" under the registry HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings, which determines the maximum number of simultaneous downloads, usually 5~8 The number of connections is better. In addition, for the HTTP 1.0 server, you can add a double-byte value item named "MaxConnectionsPer1_0Server", which is also used to set the maximum number of simultaneous downloads, or you can set it to 5-8.

8. Hotkeys in the shielded system

Click "Start" → "Run", enter Regedit, open the registry editor.

Then open to HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer, create a new double-byte value, the key name is "NoWindows Keys", the key value is "1", so you can disable The user uses the system hotkey to execute some disabled commands. To restore, just set the key to 0 or delete the key.

9. Speed ​​up menu display

At "Start"-->"Run"-->Type "Regedit"-->"HKEY_CURRENT_USER"-->"Control Panel"-->"Desktop", change the value data of the string value "MenuShowDelay" to "0". If you feel that the menu display speed is too fast after adjustment, you can change the value data of "MenuShowDelay" to " 200", restart it
