The desktop cloud system can create user desktops in batches and update desktop data, but after the desktop data are updated in batches, software and personalized configurations installed by users cannot be effectively reserved.
In the related art, by performing hierarchical management on the operating system data and the user software data, that is, redirecting modification of the user software data to an independent hierarchical protection space, after updating the operating system data, the user software data is not damaged, that is, redirecting a user registry key value and a file operation access position to the independently allocated hierarchical protection space, so that the user software data can be saved to the hierarchical protection space. However, after the registry key is redirected, when software and the operating system trigger enumeration operation, the registry key filtering driver needs to perform enumeration operation twice and perform de-duplication and then return to the operating system, so that the system performance is greatly reduced. The file redirection function takes effect after the file filtering driving module is started, and the method has limitation on some files which need to be loaded into the system memory before the file filtering driving module is loaded, so that the mirror image layering effect cannot be achieved.
