Solution for displaying hidden files in the XP System

Manual method

The Registry is maliciously modified by viruses. Here are the solutions:

Find
HKEY_LOCAL_MACHINE/software/Microsoft/Windows/CurrentVersion/Explorer/advanced/folder/hidden/showall branch. Double-click the checkedvalue in the window on the right. The key value must be 1. if the value is not 1, change it to 1.

If your settings still do not work, let's take a look.
Some Trojans set their own properties as hidden and system properties, delete the "Hide protected operating system files in Folder Options" and the "show all files and folders" option in the registry, so that procexp can be seen in the process, however, the source file cannot be found in the directory where the file is located and cannot be deleted.
In this case, you can store the following content as the showall. reg file, and double-click the file to import it to the Registry.
