This introduction is very troublesome. I will give you the address of the video tutorial:/pcedu/soft/gj/sys/0510/709175. HTML optimization expert. Automatic detection of system information: In the system information, the Windows Optimizer provides a powerful system software and hardware information detection function. It can detect information including CPU, BIOS, memory, hard disk, LAN and network card, Internet, graphics card, modem, CD-ROM drive, monitor, multimedia, keyboard, mouse, printer and software. You can also test and compare system speeds. System detection modules are divided into nine categories according to system information overview, processor and BIOS, video system information, audio system information, storage system information, network system information, other external devices, software information detection and system performance benchmark testing. 2. Disk cache. Provide disk minimum cache, disk maximum cache and buffer read-write unit size optimization; Shorten the waiting time for Ctrl+Alt+Del to close the unresponsive program; Optimize page, DMA channel buffer, stack and breakpoint values; Shorten the waiting response time of application errors; Optimize the queue buffer; Optimize virtual memory; Coordinate virtual machine work; Quick shutdown; Memory sorting, etc. 3. Menu speed optimization Using the optimization master's optimization of menu speed gives us the most obvious feeling. Windows Optimizer provides the following features. Starting the optimization of menu speed and menu running speed can speed up the running speed of all menus, and the value can be adjusted to the fastest. The optimization of desktop icon cache can improve the display speed of icons on the desktop. This option is used to set the maximum size of hard disk space occupied by files stored in the system icon cache. The adjustment range allowed by Windows is 256 kb-8 192 kb. When entering this page, Windows Optimizer can detect how much icon cache is currently used by the system. There is always nothing wrong with using the maximum value for an undetectable system. Accelerating the refresh rate of Windows actually enables Windows to have automatic refresh function. Rebuild the icon cache. In order to speed up the display, Windows will put the icons of all installed applications in the cache file, but when the application has been deleted, Windows will not delete the icon of the application in the icon cache file. This feature can help you reduce the size of the icon cache file. Turn off visual effects such as animated windows, menus and lists. For Windows9X, the Windows optimizer will close the animation display window, menu and list; For Windows2000, Windows Optimizer will turn off animated windows, menus and lists, as well as faded visual effects. For WindowsXP, Windows Optimizer turns off animated windows, menus and lists, fades in and out visual effects, and turns off menu shadow effects. 4. File system optimization Windows Optimizer provides seven file system optimization methods for different user types. Including Windows standard users; Computer game enthusiasts and users; Users with tight system resources; Multimedia lovers; Large software users; CD burner users; Recording equipment users. CD/DVD-ROM optimization. Windows Optimizer will automatically provide users with the most accurate and optimal CD/DVD-ROM access mode according to the user's memory size and available hard disk space. For users who don't use the virtual CD-ROM drive, it is recommended to adjust the adjustment bar to "Windows Optimizer Recommended Value" when setting this item. For virtual CD-ROM drive users, the adjustment bar must be adjusted to the maximum value. 5. Network Optimizer Windows Optimizer will list the detected modems at the top of the page. If the user runs under Windows2000/XP, the Windows optimizer will also list the entries of TCP/IP. MaxMTU/MaxMSS optimization: Windows' default MaxMTU (the largest TCP/IP transmission unit) is 1500 bytes (Ethernet standard), which will reduce the transmission efficiency for dial-up Internet users, and should generally be changed to 576 bytes. MaxMSS (maximum number of packets) should generally be MaxMTU-40. 6. The system security optimization function mainly includes scanning and immunizing hackers and virus programs; Prevent anonymous users from logging in with ESC key; Automatically enter the screen saver when starting; Automatically clear the history every time you exit the system; Enable Word97 macro virus protection; Automatic operation of optical disks is prohibited. In addition, a start menu is provided; Provide applications and more settings for users who need more advanced security features. Process management can view system processes, modules loaded by processes (DLL dynamic link libraries) and priorities, and can terminate the selected processes. Local port analysis can find the open TCP/IP ports in the current system, and it also provides the editing function of port description information for experienced users. Remote port scanning can detect open ports of remote computers. 7. Registry cleaning scans to delete redundant and error information in the registry, scans to delete redundant DLL information in the registry, scans to delete residual anti-installation information in the registry, and scans to delete other redundant information in the registry. 8. The main functions of file cleaning are: cleaning the hard disk according to the file type list; Clean up invalid shortcuts; Clean up zero byte files; Clean up all kinds of temporary files generated by Windows; Hard disk usage analysis; At the same time, it also provides duplicate file analysis and redundant DLL file analysis for professional users. 9. Personalized settings and other optimizations include right-click settings, desktop settings, OEM information settings, DirectX settings, AGP bus and graphics card optimization, and other settings. In other optimizations, system files can also be backed up. 10. The main function of boot optimization is to optimize the boot speed and manage the boot self-startup program.
