Windows XP hardware optimization full power (1)

        I believe that everyone wants to make their Windows XP boot faster and work more stable, then how to do it, let's briefly introduce how to optimize Windows XP. First, shorten the startup time. It is recommended that you use the Bootvis software released by Microsoft. It can automatically optimize the system to shorten the time it takes to start. Select "Optimize System" in "Trace" and restart it. You can also use Windows. XP built-in MsConfig setting program reduces the program loaded at startup to shorten the startup time. Just enter "msconfig" in the running and then set the relevant settings through "Startup". 1), Bootvis 2), msconfig Second, set the processor's L2 cache capacity Windows XP can not automatically detect the processor's L2 cache capacity, we need to manually set it in the registry, first open the registry (run "Regedit" "), then open: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\ Select "SecondLevelDataCache", according to the processor settings you use, for example PIII Coppermine/P4 Willamette is "256", Athlon XP is " 384”, P4 Northwood is “512”. Third, install UPnP security patch Microsoft recently released the UPnP security patch for Windows XP, this program fixes the security vulnerabilities in WinXP, you can update through the following address: Windows XP Home & Pro UPnP Patch IV, close System Restore and Hibernate Support Although these two features are not completely useless, considering that you need to take up a lot of hard disk space, it is best to turn them off; first click on the "My Computer" on the desktop. Select "Properties", find "System Restore", and tick "Turn off System Restore on all drives". Hibernate support only needs to go through the Control Panel -> Power Options -> Hibernate, remove the check mark in front of "Enable Hibernate", which can free up 512MB of hard disk space. 5. Release 20% of the network bandwidth occupied by the QoS Packet Windows XP built-in QoS Packet needs to occupy 20% of the network bandwidth. Fortunately, we can close it by “Group Policy”. The specific steps are as follows: Enter “gpedit. Msc", after starting the program, select Computer Configuration -> Administrative Templates -> Network -> QoS Packet Scheduler, select "Limit reservable bandwidth" on the right, set it to "Enabled", and then set "Bandwidth Limit" to "0". VI. Virtual memory (page swap file) is prohibited. This method is best used on systems with more than 256MB of memory (384MB or 512MB recommended). To do this, start the Registry Editor and find: HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\ Control\\Session Manager\\Memory Management\\ Select “DisablePagingExecutive” and set it to “1”. This can improve the performance of the memory to a certain extent and improve the running speed of the system. After all, the memory is much faster than the hard disk. Seven, delete Windo

ws XP unneeded components 1), delete system file backup, execute sfc.exe /purgecache2), delete driver backup, delete WINDOWS (XP installation directory) \\driver cache\\i386 directory Driver.cab file 3), delete the DLL backup file, the directory is WINDOWS (XP installation directory) \\system32\\dllcache, 4), delete the WINDOWS (XP installation directory) \\ime under the input method eight, verify whether Windows XP is Activated to enter "oobe/msoobe /a" in the run; the version number can be accessed through WINDOWS (XP installation directory) system32/NTOSKRNL.EXE, right mouse button -> select content to view. Nine, set the IRQ priority from HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control\\PriorityControl, and create a new DWORD key named "IRQ#Priority" on the right side, where "#" is the IRQ number of the related device, for example "8", then The key value is set to "1"; if you encounter IRQ problems, you can try this method. Ten, speed up the shutdown speed and boot, Windows XP shutdown speed is also the same slow, to speed up the shutdown speed, first we must first open the WinXP automatic end task function (AutoEndTasks) through the registry, the specific steps are: find HKEY_CURRENT_USER\\Control Panel\\Desktop, set the key value of AutoEndTasks to 1. Then modify "HungAppTimeout" to "4000 (or smaller)" (default is 50000), the key value is also in the HKEY_CURRENT_USER\\Control Panel\\Desktop directory; the last step is to find HKEY_LOCAL_MACHINE\\System\\CurrentControlSet \\Control\\, Also set the WaitToKillServiceTimeout to "4000"; the shutdown speed after this setting is obviously faster, 11. Turn off the Windows XP file protection function completely. Find HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Winlogon from the registry, modify The "SFCDisable" key value is "FFFFFF9D". If you need to re-enable the function, reset it to "0". Twelve, start the hard disk /optical drive DMA mode to open the system properties -> Hardware -> Device Manager -> IDE ATA /ATAPI controllers, select "Primary IDE Channel" or "Secondary IDE Channel" Check if the DMA mode is enabled. Generally speaking, if the device supports it, the system will automatically turn on the DMA function; in addition, the transmission mode currently used by the drive can also be seen here. Thirteen, disable the Dr. Watson debugger to enter "drwtsn32" in the run, and then remove all except the "(Dump All Thread Contexts) dump all thread context", otherwise the hard disk will ring for a long time if there is a program error, And it will take up a lot of hard disk space.
