Two wonderful ways to easily implement windows xp file protection function

Starting with Windows 2000, Microsoft introduced the "Windows File Protection" feature. WFP runs automatically in the background, which prevents important system files from being replaced, greatly improving the stability of the system. As a background running service, WFP will consume a certain amount of resources. If your computer configuration is not very high, then it can be completely disabled to improve computer performance.

The stability and security of the Windows operating system is getting more and more attention. Starting from Windows 2000, the system provides a file protection mechanism (Windows File Protection). This function can effectively protect some important system folders in Window s, such as DLL, OCX, SYS, CPL and other suffix files. And the system will automatically back up these files to the directory "%SYSTEMROOT%system32dllcache", once the protected files are destroyed or replaced, Windows file protection automatically restores these files from the dllcache directory. But how do we use file protection? Here are two ways to do it.

Method 1: Group Policy

Click “Start →Run”, enter the “gpedit.msc” command in the Run dialog box, open the Group Policy Editor, open &ldquo Computer Configuration & Rarr; Management Template & Rarr; System & Rarr; Windows File Protection & rdquo;, showing four file protection strategies in the right form? Using these strategies, you can easily define the file protection function of Windows system.

1. Set Windows File Protection Scan

This policy is used to set whether to enable Windows File Protection. Double-click the mouse to open the policy. By default, the file protection function is not enabled. Click the “Enable” option. If you want to scan the system every time, select “"Scan frequency” drop-down list box to select “ Scan during startup, if you only want to scan when installing files, select the option “Do not scan during startup”.

2, hidden file scanning progress window

When this setting is enabled, the scanning progress window will not be displayed during Windows file protection scanning. Open the policy and select “巳Enable”, click the “OK” button.

3, limit the size of the Windows file protection cache

The file protection function will back up a large number of protected files to the dllcache directory, but as the system installs more and more software, you will find The size of the dllcache directory is constantly increasing, wasting a lot of hard disk space. This strategy is used to limit the size of the dllcache directory. In the "Restrict Windows File Protection Cache Size" dialog box, click the “巳Enable” option, and then specify “buffer size", if we want to limit the dllcache directory to a maximum of 300MB, enter it in the input field. “300”Yes, finally click the “OK” button.

4, specify the Windows file protection cache location

The default location of the dllcache directory is in "%SYSTEMROOT%system32dllcache", but many friends do not want to waste system disk space, then you can use this strategy to re Specify the location of the cache file, open the policy, select “巳Enable”, then enter a new location in the "Cache File Path" input box, such as “D?BAK”, and finally click “OK” Button.

After completing the above settings, you need to restart the system to take effect.

Protecting Files with SFC Commands

The stability and security of Windows operating systems are gaining more and more attention. Starting with Windows 2000, the system provides a file protection mechanism (Windows File Protection). ). In the last issue, we talked about how to use Group Policy to implement file protection. This time, how to implement it with SFC commands. Previous12Next page Total 2 pages
