Well, I do not know that Kiano in the X3 HD + model uses only the Microsoft mechanism and there is no hidden Partition Recovery. Personally, the image of Drive with its entire structure, clean, created by Kiano by Fabian Paragon 14.0, which then recreates without any problem, provided that it does not interfere with this Disk, eg other installations of the Operating System that change a certain structure of the Disk and then restoration from this Image is no longer possible. However, the Compilation of the factory installed Windows 10 Syndrome is old and there is such a problem that after the Windows Update updates the entire disk space of this equipment is full and at this point it is impossible to even reset to Factory settings because this operation requires at least 5GB of free space on the System Partition. However, it is possible to solve this problem viz. You have to prepare for PenDrive Insaller the latest Compilation of this Win 10 Home 64bit system because it is on the device in the version with 4GB RAM. Then, when you receive this clutch from the store or the Kiano Website after its reinstallation and without any updates, it is first of all necessary to make a backup copy of the Drive on an external medium, eg Paragon Application in version at least 14.0. Then, from the position of the working System, run the Installer of this latest build from PenDrive. When the Installer asks whether to immediately update from the Internet, note that it does not !!! and continue installing to the end.
After the installation is completed, do not update from the Internet and go to: Start / Settings / System / Memory / Change the method of freeing space and select (remove System pop-up) / Clean now. After this operation, Everything will be OK and again will be available for almost 14GB of free disk space. That's for the beginning because you can still install an additional MicroSD 23 or 64GB card into the SD card reader and of course with the knowledge of the subject, redirect the entire Catalog with subfolders (User Directory) to the other location. Also, when installing new Applications, choose to install them on the second Memory. Now you can connect to the Internet and update Windows Update. Remember to check and, if necessary, delete the old, unnecessarily occupied version of the System after each major Update. I have all installed and updated, and I still have free space in the C 10 Disk. Factory Kiano drivers can be pulled out. The "My Drivers" application can always be useful in case of unforeseen problems.
