ProfilesDirectoryThe ProfilesDirectory setting specifies the path to the user profile folder. Caution: This setting should be used only in a test environment. If you change the default location of the user-profile directories or program-data folders to a volume other than the system volume, you cannot service your image. Any updates, fixes, or service packs will not be applied to the installation. For a list of known issues with this setting, see Description of known issues with the FolderLocation settings.. Using this setting to redirect folders to a drive other than the system volume blocks upgrades. Using ProfilesDirectory to point to a directory that is not the system volume will block SKU edition upgrades and upgrades to future versions of Windows®. For example, if you use Windows 7 Home Premium with ProfilesDirectory set to D:\, you will not be able to upgrade to Windows 7 Ultimate or to the next version of Windows. The servicing stack does not handle cross-volume transactions, and it blocks upgrades. Use this setting to move the user-profile folder (typically %SYSTEMDRIVE%\Users) to another location during Setup or when Sysprep is running. The destination path can be on a volume other than the system drive, as long as it meets the following requirements: It must be on an NTFS volume. It must not be the path of another operating system user-profile folder. It must not contain any serviceable components. This setting can be used to keep system data separate from user data. If Windows® is re-installed on the system volume, a user with administrative rights can manually recover data from this location. ValuesPath_to_profiles_directory Specifies the path to the user profile folder. Path_to_profiles_directory is a string with a maximum length of 256 characters. This string type does not support empty elements. Do not create an empty value for this setting.
