Modify the default installation path and local user configuration file storage path of XP

Modifying the registry may cause your system to crash or data loss. Please back up the operating system first for emergency !!!

To back up the registry:
1. Press the shortcut key "Ctrl + R" on the "desktop" to bring up the "run" window. Then, enter "Regedit" in the input box after "open ". Click OK. For example
 
2. Select "my computer" in the registry ". For example.

3. Select "file"> "Export"> select the path and file name. Likewise, registry backup and Restoration: "file" → "import" (this is only for the entire registry ).

1. Modify the default installation path of XP software:
Find [HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion],
In the window on the right, find the string "programfilesdir", which records the path of program files.
Double-click to change the value from "% systemdrive % \ Program Files" to "D: \ Program Files", and then exit the registry.
You can also change the "commonfilesdir" string in the right window to "D: \ Program Files \ common files", so that the public folder of the software is also transferred out of drive C.
The default path for the next software installation is: "D: \ Program Files ".
[Note: you do not need to restart the computer .]

2. Modify the local user configuration file storage path
Find the [HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ profilelist] project. You can see the current location of the user configuration file. For example

Different from Windows 7, Windows XP does not allow users to select the "user configuration file template" and "public folder" positions separately, which must be adjusted at one time. Directly modify the key value of "profilesdirectory" indicating "user configuration file location" to the desired folder. "% Systemdrive %" in the default value indicates the hard disk partition where the default system is located. For example

After "user configuration file location" is modified, the "user configuration file template" and "public folder" Folders will not be automatically copied to the modified location, however, in the path where the new "user configuration file location" is located, if the two folders do not exist, the user cannot log on normally. Therefore, you need to manually copy these two folders to the new location.

Select, "show all files and folders" on the "View" tab, and select "OK" (modify the location of the "user configuration file template" and change it back to the default value ).
Open the Documents and Settings folder under "system partition (drive C)", copy the "Default User" and "all users" folders, and copy them to the new location set when you modify the registry. For example

After completing the preceding operations, restart the computer. After a user is created, the system automatically creates a user configuration file folder with the same name as the user name in the new location.
