1. When the WFP work principle is first installed for Windows XP, the file ended in DLL, EXE, FON, OCX, SYS and TFF will be identified by the WFP as an important system file and back up these files under the DLLCache folder. During the user using a Windows2000 / XP system, the WFP will back up files with AX, CPL, CPX, DLL, EXE, FON, INF, OCX, RSP, SY, FON, INF, OCX, RSP, SYS, TFF, and TLB under default settings at% / System32 / dllcache folder. If these system files are accidentally deleted or destroyed, WFP can use backup files under Dllcache to easily restore Windows file systems. Second, how to upgrade the operating system file with WFP functions Since the WFP can automatically restore the original system files with backups, the operating system files with WFP cannot be upgraded with a general method. Here is a common method of several upgrades: 1. Install the Windows service component. 2, upgrade the Windows system. 3, run hotfix.exe. HotFix automatically updates the system files backed up by the WFP. Most HotFix programs have been packaged within Windows service components. If you have installed the Windows XP Service Component 1, open "Add / Remove Programs" You can see the following 2 HotFix programs: 4, use the Winnt32.exe running system installation / upgrade program. In addition, there is a simple manual upgrade method that copies the file to which you want to upgrade to the DLLCache folder, and then the WFP can automatically upgrade the Windows file system. Third, the skip preparation work before running the WFP program, the user must first log in as system administrator. The system administrator's identity will provide you with a fairly convenient condition for configuring configurers related to WFP. Although maybe you may not need, but here still recommend you to make an emergency repair disk for use. After completing the relevant settings, the exit system logs in with the normal user, so we can use WFP. Fourth, the use of WFP and configuration can complete the modification configuration of the appropriate option in the Group Policy editor. Click Start / Run, enter GPEDIT.MSC, and turn on the computer configuration management template after entering bus, select the Windows File Protection folder. Double-click the option to select the option under the Setting Tag. For the SET Windows File Protection Scanning option, select Enable allows the WFP to scan the backup file when the system is started, and the system file is replaced if necessary, but select this will extend the startup time of Windows. For the Hide The File Scan Progress Window option, select "Disable", Windows will no longer display the WFP program list. For the Limit Windows File Protection Cache size, under the default setting, the hard disk space occupied by DLLCache is unlimited. The file system to be backed up by the WFP is quite large, and when the file is placed in a high-speed memory, it is necessary to take up additional hard disk space. . Select "Enable" and enter the value you want, and the unit is MB byte. For the Specify Windows File Protection Cache Location option, if you want to change the default path, select "Enable" and enter the file directory path you want. The path under default is YSTEMROOT / SYSTEM32. If you want to further configure the WFP setting, click Start / Program / Accessories, select the command prompt mode. The figure below describes several SFC parameters commonly used in the DOS interface. Regarding the sfc / scannow.wfd parameters, after the Enter key is pressed, then start scanning all backup files while replacing the incorrect system files in all versions.
Regarding the SFC / ScanBoot parameter, after restarting, the WFP starts scanning each time the system starts. The above two can also be performed by modifying the registry, open the registry [HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / WindowsNT / CURRENTVERSION / WINLON] key, change the key value of New DWord Value Right Click to SFCSCAN in the right side of the board. Turn the value of valuedata to 0, use the default WFP function; input 1 Make WFP to scan the system files for each Windows startup; enter 2, WFP will scan all system files after the next startup. After restarting, the registry modification takes effect. Regarding the SFC / Cancel parameter, only the Windows 2000 is valid, all WFP scans for backup system files will be canceled, but this command does not take effect under the Windows XP system. Regarding the SFC / Quiet parameters, only the Windows 2000 is valid, WFP will replace all versions of incorrect system files with backup files under DLLCache. This command does not take effect in Windows XP. With regard to the SFC / PurgeCache parameter, the command will clear all the files under the Dllcache folder. Regarding SFC / Cachesize = X parameters, under default, WFP will back up all system files, so that once problems can be fully recovered, when a part of the backup file is loaded with a high-speed memory, WFP also takes up additional hard disk space. The value of x represents the maximum space that can be entered DLLCache folder. These two commands will return WFP to default settings regarding SFC / Revert parameters and SFC / Enable parameters. Using SFC / Revert under Windows XP, SFC / Enable is used under Windows 2000. Now you have been quite understanding of the excellent performance of Windows File Protection, how to make it more effectively serve your operating system, although WFP will take a part of the system resources, and you can also choose to disable WFP in Windows, but if Your computer configuration is high, I would like to suggest you to ensure that the system's stability, don't choose to disable WFP below is the reason why I have a Windows file protection warning box to the system: 1 system poisoning. See w32.xorala: http: //it.rising.com.cn/newSite/Channels/anti_virus/Antivirus_Base/TopicExplorerPagePackage/win32_xorala.htmhttp: //it.rising.com.cn/service/technology/RS_xorala.htmW32.Valla .2048: http://www.symantec.com/avcenter/venc/data/w32.valla.2048.html
2 Software issues, some old or unwell software will replace the system file, and this prompt box will also appear; check the compatibility of your installation software in non-toxic case, then insert the disc, use SFC recovery files Usage Yes, click Start / Run, type command: SFC / ScanNow, determine. Sometimes there will be a case where you don't know, you can manually restore the system file. Insert the disc, and so on the system to recognize the disc, click Start / Run, type SFC / ScanNow to determine. If your system has installed patches, your original disk does not patch, this method is invalid. For example, you have installed 2000sp4, you must put it into the CD of SP4. First put the CD into the CD-ROM drive, be sure to put it in advance! Then click Start / Run, enter SFC / ScanNow to determine. Also note: CDs with Windows2000 3 are not available to repair system files in this way. 3 If you use the pirated disk (Windows XP) when installing the system, then you activate (an algorial, Russian phone patch, automatic activation program, etc.), will also appear WFC warning box; start running SFC / PurgeCache to start running gpedit .msc (group policy) Computer configuration => management template => system => Windows file Protects the setting of the right side to disable Start Running Regedit or RegedT32 Find [HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows NT / CurrentVersion / Winlogon on the right pane Right-click Click Select New -> DWORD VALUE to name SFCDISABLE Enter the key value for FFFFFFF9D to turn off the WFP restart system to turn off the WFP restart system to take effect. To ensure that WFP is already closed, you can view log files after restarting your computer. Click Start -> Settings -> Control Panel. Open Administrative Tools -> Event Viewer. You will see the records shown in the figure. The WFP is turned off after each Windows 2000 is started. Note: Although the WFP is turned off, the file is still backed up under the DLLCache folder. This should be removed after the WFP is turned off. Just open the% systemroot% / system32 / dllcache this folder, then delete the files in the directory is.
4 more specific: XP system, will pop up file protection for a while, say that the installation language does not meet the start of SFC / Scanonce restart; Windows2000Server, after installing office2000, always pop up a dialog, say system files, let insert If the installation disk, if you do not insert, you will go to the bounce as described in the split. Or replace office XP;
5 If you are a system, you can start running SFC / Scannow or a good solution; (^_^)
