I. How to Use the boot password of any computer

A little trick can be used to understand the password of any computer, without any tools or discharge. When a computer needs a password, you only need to open the chassis, unplug the sound card or any other part in the device, power it on, and shut down the device after self-check on the motherboard. Plug the unplugged part into the device, start the device, and clear the password automatically, experiment with bailing.

2. Make your keyboard speak

For a long time, we will inevitably get tired of our silent computers. If the input content is read by the system, can you still enter the wrong content in silence? Take a little-known "narrator" in Windows 2000/XP as an example to teach you how to DIY a completely free voice keyboard.
In "run", enter"Narrator", Click"OK". Click "OK" and skip it. The main character of this article-"narrator" will be displayed ". What do you hear if your speaker has been turned on? If you don't want to listen, press Ctrl. Try again by pressing any key. The keyboard you entered was read by the system in standard American English, and a completely free voice keyboard was born in your hands.

5. Speed up on/off

When shutdown in Windows XP, the system will send a message to the running program and remote server, telling them that the system is shutting down and the system will start to shut down after receiving a response. To speed up the boot process, you can first set Automatic task termination, first findCURRENT_USER \ Control Panel \ DesktopAutoendtasksTo1; Then there is a"Hungapptimeout", Change its value to"4000(Or less).

When a Windows XP Network Neighbor is used, the system searches for its shared directory, printers that can be used as network shares, and scheduled tasks related to the network in the scheduled task, the speed will obviously be much slower. If these functions are not very useful to us, we can delete them. In the Registry Editor, findHKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ remotecomputer \ namespace, Delete(Printer)And(Scheduled tasks), Restart the computer and access the network neighbor again. You will find it much faster.

Follow these steps to make better use of the CPU efficiency:HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ prefetchparametersRight window, SetEnableprefetcherThe numeric data of is changed as follows. For example, we recommend that you change the numeric data4Or5Otherwise, we recommend that you retain the default value:3.

13. Reduce project loading during startup

Many applications are automatically added to the system startup group during installation. Each time the system is started, the system runs automatically. This not only prolongs the startup time, but also consumes system resources after the system is started!
Start the "System Configuration Utility", list the projects and sources loaded during system startup in the "Start" item, and carefully check whether you need it to be automatically loaded, otherwise, clear the check box before the project. The fewer projects to load, the faster the startup speed. This item must be restarted to take effect.
