WinXP automatically updates the downloaded update program. What is the default save path?

Save Path Problem Description

WinXP system if you want to download the update patch automatically saved for later use, but I do not know automatically updates the downloaded update program

resolved Scenario

WinXP system automatically updates each time you upgrade, the downloaded patch is first placed in C:\\WINDOWS\\SoftwareDistribution\\Download\\, and then extracted to C:\\WINDOWS\\$hf_mig$ and other directories (hidden folder) The directory contains the installation information file that was generated when the system patch was installed. The files in C:\\WINDOWS\\SoftwareDistribution\\Download\\ are automatically cleared after the system is upgraded and restarted. Therefore, after the automatic update and download of the patch, the user can directly download the patch to C:\\WINDOWS\\SoftwareDistribution\\Download and save it to another path. The patch file can also be found by entering the C:\\WINDOWS\\$hf_mig$ directory (hidden folder).
