The following are tips and setup methods for system acceleration and system optimization in Microsoft Windows 2003/XP/vista. It is a widely used "common setting" among netizens. Settings may be inconspicuous or ineffective in individual system environments.
Speed up the switch
"Start" -> "Run", type "regedit" in the open box and click "OK" to open the Registry Editor. Navigate to "HKEY_CURRENT_USER\\Control Panel\\Desktop".
Find "AutoEndTasks" and set its key value to 1;
Find "HungAppTimeout" and change its value to 200, the default is 50000;
The "MenuShowDelay" primary key, change its value to "0" to remove the menu delay effect;
Find "WaitToKillAppTimeout", change its value to 1000, the default is 20000.
Navigate to "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Control".
Set "WaitToKillServiceTimeout" to "200", so the shutdown speed is significantly faster after setting.
Locate the HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Shutdown branch and create a new string value named "FastReboot" in the right window and set its value to 1. Restart the computer after exiting the Registry Editor for it to take effect. This will restart the computer much faster.
Reduce the boot scroll time
To speed up the blue scroll bar when Windows starts, you can open the registry editor and navigate to "HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager \\Memory Management\\PrefetchParameters", find the "EnablePrefetcher" primary key on the right, change its default value from 3 to 1, so that the scroll bar scroll time will be reduced.
Clear the DLL file that is not used in memory
Locate 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.)
Turn on the startup optimization function
Locate HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Dfrg\\BootOptimizeFunction and enable Enable. It is "Y".
improve broadband speeds
Windows default reserves 20% bandwidth, which for personal users no big role, rather than let it idle Mo better to take advantage of it. Start -> Run, type gpedit.msc to open the Group Policy Editor. Find "Computer Configuration" -> "Administrative Template" -> "Network" -> "QoS Packet Scheduler", select "Restrict Reservable Bandwidth" on the right, and select "Properties" to open the Restriction to retain the Bandwidth Properties dialog. In the box, select "Disabled". This frees up the reserved bandwidth and is very useful for making the most of bandwidth and speed when surfing the Internet.
Optimize visual effects
Right click on "My Computer", select "Properties", select "Advanced" in the category view, and click "Settings" on the "Performance" tab. The “Performance Options” window will pop up, click “Adjust to Best Performance” on the “Visual Effects” tab, then “OK”, so that the animation effect of the menu can be removed, and the speed should be significantly improved.
reduce disk detection delay time
DOS command executed chkntfs /t: 0 to reduce the waiting time when a disk is detected, it indicates the waiting time is 0 seconds, or 0 if not specified otherwise The number of seconds, just chkntfs /t, shows the current settings.
