Windows XP and 2000 include a technology called WFP (Windows File Protection, Windows File Protection) and a System File Checker. This feature can avoid problems with some common DLL files. This function also prevents users from replacing the required system files or performing some operations on the system files. However, this feature allows you to disable it through the following settings.
HKEY_LOCAL_MACHINE/software/Microsoft/Windows NT/CurrentVersion/Winlogon,
Set the key value of the "sfcdisable" key to "ffffff9d" to disable WEP, and set it to "0" to enable it. Other available key values are as follows:
1-Disable, but you will be asked if you want to enable it again when the system starts.
2-disable it only during the next restart and do not ask if you want to enable it again
4-enable and do not display the pop-up window
Ffffff9d-completely disabled
The settings you modified will take effect after you restart your computer.
