Windows 7 boot speed is a little slow solution

I. Software Article 1. Setting up a virtual memory hard disk has a very big data exchange file, which is a place for the system to reserve virtual memory for temporary storage and is frequently used by many applications, therefore, the system often needs to perform a large amount of data access to the primary storage. Therefore, the speed of accessing this file constitutes a very important factor affecting the speed of the computer! In Windows, virtual memory is automatically managed by the system, which automatically adjusts the size of swap files based on the needs of different programs. However, increasing or downgrading this will cause additional burden on the system, this slows down system operations! As you can see, it is recommended that you customize the minimum and maximum values of the virtual memory to avoid frequent resizing. To set the virtual memory, right-click "my computer" and select "properties". In the "performance" dialog box in the "advanced" option, set "Virtual Memory. 3. Check the application software or driver. Some programs will slow down the system when the computer system starts. If this is the reason, we can start it in "security mode. Because this is the original startup, "safe mode" is slower than normal running. However, if you use "safe mode" to start and find that the computer starts faster than normal, a program may be the cause of slow system startup. 4. Too many desktop icons will make it difficult to have too many icons on the desktop and reduce the system startup speed. Every Time Windows starts and displays the desktop, you need to find and load the Desktop shortcuts one by one. The more icons, the more time it takes. At the same time, some anti-virus software provides the system startup scanning function, which will take a lot of time. In fact, if you have enabled the real-time monitoring function of anti-virus software, scanning the system at startup seems redundant. disable this function! We recommend that you put unused desktop icons in a dedicated folder or simply delete them! 5. the system starts slowly due to ADSL. By default, Windows XP performs self-check on network devices such as network adapters during startup, if you find that the IP address of the network card is not configured properly, it will be set. This may be the real cause of slow system startup. In this case, you can open the "local connection" attribute menu and double-click "Internet Protocol" in the "General" item to open the "TCP/IP attribute" menu. Configure the IP address of the network adapter as an unused value in the public network (the default gateway is 192.168.1.1), for example, 192.168.1.x. The value of X is between 2 and 2 ~ The value between 255 and the subnet mask is set to 255.255.255.0. The default gateway and DNS can be set by default. 6. The influence of fonts on speed, although Microsoft claims that Windows operating systems can install 1000 ~ 1500 types of fonts, but in fact, when you install more than 500 types of fonts, problems will occur, such as: the font disappears from the application's font list and the Windows Startup speed is greatly reduced. We recommend that you delete unused or infrequently used fonts. To avoid unexpected deletion, perform necessary backup first. 7. delete a random Start program. What is a random Start program? A random Start Program is a program loaded at startup. The random Start program not only slows down the boot speed, but also consumes computer resources and memory more quickly. Generally, if you want to delete the random Start program, you can delete it in the "Start" list, if you want more details, such as QQ, popkiller, and other software, you cannot delete them in the "launch" list. You need to "affiliated Applications" and then "System Tools ", go to "system information", click "Tools" in the tool column above, and then click "System Configuration editing program". Then, in the "Start" dialog box, the random boot program loaded when the computer is started will be listed in detail! In the XP system, you can also enter msconfig to call the System Configuration Utility to terminate the system random Startup Program. 2000 the system needs to copy the msconfig program from XP. 8. Canceling background and disabling activedesktop I wonder if you have noticed that we have always placed beautiful backgrounds on the desktop, which is a waste of computer resources! Not only that, but it also slows down the speed at which the computer executes applications! We wanted to beautify the desktop, but slowed down the speed of the computer, so we don't need to use the background anymore. The method is: Right-click the desktop and then press the content, then, in the "background" dialog box, select "NONE". In the "appearance" dialog box, change the default "green" to "Black ...... to close activedesktop, you can close the Web screen from the desktop. For example, right-click the desktop and then press the content. Then, in the "background" dialog box, there is a background, the name is Windows XX, which is a Web screen! Therefore, do not enable this function if the system configuration is not high. 10. Make Windows more slim than the DOS system. Windows is too large. With your daily operations, installing new software, loading runtime libraries, adding new games, and so on makes it more huge, more importantly, it is not only its directory, but also its registry and Runtime Library. Because even if a program is deleted, the DLL file used by the program still exists. Therefore, as the program is used for a long time, the DLL dynamic link library files to be loaded during Windows Startup and exit become larger and larger, the running speed of natural systems is getting slower and slower. In this case, we need to use some programs that completely delete the DLL to restore windows to a slim fit. We recommend that you reinstall windows every two months. This is very effective. 11. Although you already know how to add and delete some random boot programs when you change the system boot time, do you know that during the period from boot to windows, what is the computer doing? Or, what program is executed? Those programs must be fully loaded before entering windows. Have you ever thought that if you can delete unnecessary programs during startup, will the boot speed be accelerated? The answer is yes! To modify the settings, press start, select execute, and type win. INI. After it is enabled, you can delete the content of the following sections. Delete the content and do not delete the title! They include: [compatibility], [compatibility32], [imecompatibility], [compatibility95], [modulecompatibility], and [embedding]. Ii. Hardware Article 1. Shut down the hard disk DMA mode in windows. We should all know that the PATA mode of the hard disk includes dma33, dma66, dma100, and dma133, the latest SATA-150 has come out! Generally, most people use the PATA hard disk. The hard disk uses the DMA mode, which is 2 ~ faster than the previous Pio mode ~ 8 times. The use of the DMA mode plays a substantial role in the system performance. But do you know? In Windows 2000, XP, and 2003, the hard disk's DMA mode is sometimes disabled and automatically switched to Pio mode! This results in a sudden decline in hard disk performance in the above system, the most obvious phenomenon is: the system boot speed is obviously slow, generally, when a Windows XP system is started, the slide from left to right can be up to 2 ~ The system can be started four times, but this problem may take 5 ~ 8 times or more! In addition, the hard disk operation is obviously slow when running the system. When running some large software, the CPU usage often reaches 100%, causing a pause. When playing some large 3D games, the screen is obviously paused, when the above problem occurs, you 'd better check whether the DMA mode of your hard disk is disabled by the Windows system. Check whether your system has enabled the DMA mode:. double-click "Management Tools", and then double-click "Computer Management"; B. click system tools, and then click Device Manager. C. expand the "Ide ATA/atapi controller" Node; D. double-click your "Main ide controller"; 2. Check whether the CPU and the fan are operating properly and cooling enough. When the CPU fan speed slows down, the CPU temperature increases. To protect the CPU security, the CPU automatically reduces the Running frequency, which causes the computer to run slowly. There are two methods to detect the CPU temperature. You can use the finger method to test whether the temperature of the processor is hot, but note that you must unplug the power plug before using this method, then a ground wire is connected to prevent the static electricity on the body from penetrating the CPU and causing damage. Another scientific method is to use a multimeter with a temperature sensor to detect the temperature of the processor. The appropriate temperature varies depending on the type and model of the processor. But in general, the temperature should be less than 110 degrees. If you find that the processor test is higher than this temperature, check whether the fan in the chassis is working properly. 3. The impact of USB and scanner is caused by the detection of each drive (including the optical drive) during Windows startup. Therefore, if the optical drive is placed in the optical drive, the startup time of the computer will be extended. So if a computer is installed with a scanner or a USB hard disk is connected at startup, try to disconnect them first to see if the startup speed has changed. Generally, due to the slow speed of the USB interface, the corresponding device will have a significant impact on the startup speed of the computer. Try to connect the USB device after startup. If you do not have a USB device, we recommend that you disable the USB feature directly in the BIOS settings. 4. Is disk compression used? Because "disk compression" may cause a sharp drop in computer performance and slow down the system speed. Therefore, you should check whether "disk compression" is used. In this case, right-click "my computer" and select "attribute" from the pop-up menu, to check the properties of the drive. 5. If the NIC is improperly set, the NIC will significantly affect the system startup speed. If your computer is connected to the LAN, after installing the NIC driver, by default, the system automatically obtains the IP address through DHCP, but most companies' LAN does not have DHCP servers. Therefore, if you set it to "automatically obtain the IP address ", when the system starts, it will constantly search for DHCP servers in the network until the IP address or timeout is obtained, which naturally affects the start time. Therefore, it is best for LAN users to specify a fixed IP address for their computers. 6. When folders and printers are shared and Windows XP Professional Edition computers are installed, the startup may be very slow. Sometimes the system seems to be dead. After logging on to the system, the desktop does not appear, and the computer is like stopping the reaction. It can be used normally after 1 minute. This is because, after the bootvis.exe program is used, the mrxsmb. dll file adds 67 seconds for the computer startup! To solve this problem, just stop the shared folder and printer: Select Start → settings → network and dial-up connections, right-click local connection, and select Properties ", in the displayed window, cancel the check box before Microsoft network file and printer sharing under "Use the following selected components for this connection" and restart your computer. 7. Improper configuration of system accessories some users tend to ignore some small items when assembling machines, resulting in improper configuration of computer accessories and a speed bottleneck. For example, some friends choose a high CPU grade, but they can use sound cards but have bought ordinary cheap goods. In fact, this is often not worth the candle. In this way, the computer needs to adopt software decoding because the sound card occupies a high CPU resources and its data transmission speed is slow when running a game or playing a video disc, it often causes audible pauses, or even program running intermittently. Another example is that some of my friends' machines are upgraded. In the past, some components on old machines, such as memory stick, were reluctant to be discarded and used on new machines. However, due to the speed limitation of old memory, it is often necessary for new machines to lower the speed to accommodate it, thus reducing the performance of the entire machine and greatly affecting the overall operation speed. 9. Disconnect unused network drives. to eliminate or reduce the number of network connections that windows must establish again, we recommend that you disconnect unnecessary network drives, that is, access my computer ", right-click the network drive that has been mapped and select "disconnected. 10. One of the advantages of the lack of sufficient memory Windows operating system is the multi-linear and multi-task performance. The system can use the CPU for time-sharing operations so that you can do many things at the same time. But there are naturally some advantages and disadvantages, and multi-task operations will also put forward higher requirements for your machine. Friends know that even the most commonly used word software requires about 16 MB of memory, and 64 MB of memory is not enough when running large software such as 3D Max. In this case, the system automatically uses the hard disk space to virtualize the primary memory for running programs and storing swap files and various temporary files. Because the hard disk is a mechanical structure, and the memory is an electronic structure, the speed of the two is several orders of magnitude. Therefore, using the hard disk to virtualize the main memory will greatly reduce the running speed. 11. One of the disadvantages of using the Windows System Platform with insufficient hard disk space is that you are not clear about file management. Sometimes you do not know whether the file is useful to the system, as a result, the number of files in the Windows directory is increasing, and the capacity is also growing. In addition, the current software prefers to grow bigger and bigger, and some temporary files generated by the system, swap files, all of these will make the hard disk available space smaller. When the available space of the hard disk is small to a certain extent, there will be a lack of available space for the system's swap files and temporary files, reducing the operating efficiency of the system. More importantly, because we frequently store and delete various software on the hard disk, the available space on the hard disk becomes fragmented. Therefore, the system often does not store files in a sequential order, this will cause the system to frequently move the head when storing and reading files, greatly reducing the system operation speed. 12. There are too many hard disk partitions. If your Windows 2000 instance is not upgraded to SP3 or SP4, and too many partitions are defined, the startup may be too long or even suspended. Therefore, we recommend that you upgrade the latest SP4, and do not divide the hard disk into too many areas. Windows must load each partition at startup. As the number of partitions increases, the total time required to complete this operation will also increase. Iii. Virus article if your computer is infected with a virus, the system will run slowly. After the virus invaded the system, it first occupied the data base of the memory, and then began to constantly replicate itself in the memory. As it grew larger, it quickly occupied a large amount of memory, this causes the program to slow down or even fail to start due to the lack of primary memory. Meanwhile, virus programs will force the CPU to execute useless junk programs and keep the system busy, this affects the running of Normal programs and slows down the computer speed. Next we will introduce several viruses that can slow down the system. 1. Bride virus type that slows down the system: hacker program Attack Time: Random transmission mode: network infected objects: Network vigilance:★★★★Virus Description: This virus can run normally in Windows 2000, Windows XP, and other operating system environments. The website will be automatically connected during running. If the website cannot be connected, the virus will sleep for several minutes, and then modify the Registry to add itself to the Registry self-startup Item, the virus will release four viruses and a vulnerable virus email, and send out emails via the email system. The virus will also release funlove virus to infect LAN computers, finally, the virus will kill dozens of known anti-virus software to invalidate them. Virus Characteristics if the user finds these characteristics in the computer, it is likely to be infected with the virus. · The website will be automatically connected after the virus runs. · Virus releases the bride.exe, msconfig.exe, and regedit.exe files to the system directory, and releases the help. eml and assumer.exe files to the desktop. · The virus will add the path of regedit.exe to the hkey_local_machinesoftwaremicrosoftwindowscurrentversionrunentry of the registration table. · When the virus runs, A funlove virus will be released and executed. The funlove virus will multiply in large numbers in the computer, resulting in system slowdown and network congestion. · The virus looks for the email address in the computer and sends a large number of emails to the computer according to the address. The title is <infected computer name> (for example, if the user's computer name is Zhang Dong, then the virus mail is titled Zhang Dong. · Viruses will also kill dozens of well-known foreign anti-virus software. If the user finds all or part of the above phenomena in his computer, it is likely that the bride (worm. Bride) virus is involved. Ask the user to immediately clear it with the antivirus software in his hands. 2. avilun virus that slows down the system type: worm virus attack time: Random transmission mode: Network/file infected objects: Network vigilance:★★★★Virus Description: This virus can run normally in Windows 9x, Windows NT, Windows 2000, Windows XP, and other operating system environments. During virus running, the system restores itself to the temp, system, and recycled directories and generates random file names. After the virus runs, it will consume a lot of system resources, significantly slow the system down, and kill some running anti-virus software, and establish four threads to spread wildly in the LAN. Virus features if the user finds these features in the computer, it is likely to be infected with the virus: · During virus running, the user will be re-transmitted to the temp, system, and recycled directories, the file name is random. When the virus runs, the system will obviously slow down. The virus will kill some running anti-virus software. The virus will modify the Registry's auto-start item for self-start. The virus will establish four threads to spread in the LAN. if you find all or part of the above phenomena on your computer, it is very likely that the "afulun (worm. avron) "virus, because the virus does not have a fixed virus file name, it is best to use anti-virus software to clear. 3. Name of the virus infected by the malignant worm: worm. chinese Sasser name: earthquake wave virus alias: W32/Sasser. worm [McAfee] virus type: Affected worm system: winnt/Win2000/WINXP/win2003 virus infection symptoms: · inexplicably crashed or restarted the computer; · The system speed is extremely slow and the CPU usage is 100%; · The Network slows down. · the most important thing is that a process named "avserve.exe" is running in the task manager! Method of destruction: · The LSASS vulnerability on the Windows platform is widely used to enable hundreds of threads to constantly attack other online systems and block the network. The virus attack behavior can cause the system to stop counting down and restart. · Unlike most recent worms, the virus does not spread through emails, but instead downloads and runs specific files from vulnerable machines to infect them. · File name: avserve.exe solution: · please upgrade your operating system to avoid attacks · Please enable the Personal Firewall shielding port: 4454265554and 9996, anti-Stop program named avserve.exe to access the network · manual solution: first, if the system is winme/WINXP, disable the system restoration function first. Step 1, right-click the virus process in Process Manager and choose task manager from the shortcut menu ", call up the Windows Task Manager window. In the task manager, click the "route entry" tab, find "virus route entry" "avserve.exe" in the example table column, click "End Process", click "yes", end the virus process, and disable "Windows Task Manager". Step 2, find and delete the virus program, go to the system installation directory (winnt or Windows) through "my computer" or "Resource Manager", find the file "avser ve.exe", and delete it; then go to the system directory (winntsystem32 or windowssystem32), find the file "* _up.exe", and delete them. Step 3, clear the entry added to the Registry to open the Registry Editor: click Start --> Run, enter regedit, and press Enter. In the left-side pane, double-click (search by arrow, find it, and then double-click): hkey_current_usersoftwaremicrosoftwindowscurrentversionrun in the right pane, find and delete the following project: "avserve. EXE "= %systemroot=avserve.exe close the registry editor. Part 2 system acceleration 1. Windows 98 1. Do not load too many random Start Programs. Do not load too many unnecessary random Start Programs at startup. You can hook up before renewal. You do not need to hook up other items. Select the items and click "OK. 2. Convert the system file format from fat16 to FAT32. 3. Do not use the background easily. Do not use activedesktop, otherwise, the system will slow down (right-click the screen, choose Display Properties, click Web tags, and cancel all the options for "Active Desktop" and "channel ). 4. Set the virtual memory to three times the machine memory. For example, if the memory is 32 MB, set the virtual memory to 96 MB, the maximum and minimum values are the same (this setting can be set through "Control Panel> system> performance> Virtual Memory ). 5. For some optimization settings, go to the control panel and select system> performance> file system ". Change "computer main purpose" of the hard disk label to a network server, and "pre-read optimization" to full speed. B. In the "Floppy Disk" tab, "Search for a New floppy disk. C. In the CD-ROM, The append cache is adjusted to the maximum speed, and the access method is 4 times faster or faster CD-Rom. 6. regularly organize the system and use the following tools: disk scanning, disk cleaning, fragment, System File Checker (ASD), drwatson, etc. Ii. Windows 2000 1. Upgrade file system A. If your operating system is Windows 9x and Windows 2000, we recommend that you use the FAT32 format for the file system format, in this way, hard disk space can be saved, and resources can be shared between 2000 and. Reminder: To achieve this double start, it is best to install 9X in Zone C in a pure DOS environment first, in 9x or start with Win 2000 boot disk in DOS environment, install 2000 in another zone, and at least 2000 MB space is required in this zone. If you only use win, we recommend that you convert the file system format to the NTFS format, which can save hard disk space and improve stability and operation speed, and the file system format has good error correction, the DOS and Windows 9x systems cannot run in this file system format. This is also the reason why we recommend that you use the FAT32 format to ensure resource sharing during the double boot. In addition, some applications cannot run in this file system format, most of which are dos games. Reminder: to upgrade the file system to NTFS format in Win 2000, click Start-Program-attachment and select "command prompt ", then enter "Convert drive_letter:/Fs: NTFS" in the prompt window, where "Drive" is the hard disk partition symbol you want to upgrade, such as area C. You must also note that, upgrading the file system does not damage the files in the hard drive partition and does not require backup. · Run "Add-delete program" and you will see an additional option "Add/delete Windows Components". B. Open "Folder Options ", in the "View" tab, select "show all files and folders". In this case, autoexec will appear under the root directory of the partition under your Windows 2000 installation. BAT and config. in fact, there is no content in the two files. You can delete them safely. C. Right-click "my computer", select "manage", and click "service" under "services and applications, you will see various program groups loaded on Windows 2000. Many of them are about LAN Settings or other functions. You can disable programs you do not use, such as alertr, if you are not in the LAN, you can set it to disabled; and fax service, disable it if you do not send a fax; print spooler, no printer is set to use; uninterruptible power supply, if no ups is available, you can also disable it. You can set these loaders based on your actual situation. Descriptions and running status are provided after each loader. Select the program to be disabled, right-click it, select "attribute", and click STOP, set "Start type" to "Manual" or "disabled". D. Disable the debugger dr. watson; run drwtsn32 to remove all except the "dump all thread context. Otherwise, once a program error occurs, the hard disk will ring for a long time and occupy a lot of space. If you have encountered this problem before, find the user. dmp file and delete it, which may save dozens of megabytes of space. This is the scene of the wrong program, and it is useless to us. In addition, memory. dmp displayed on the blue screen can also be deleted. Can be turned off in my computer/Properties
