Hi edohikmahtiar,
Thank you for your post. I am sorry to hear that you are unable to get the update. That is concerning that even after a refresh you cannot get the update.
To confirm, have you tried getting the update using a different Wi-Fi connection and/or from a different location?
If so and you still cannot install the update, you might want to consider trying a reset.
Note: A reset reinstalls Windows and apps that came installed on your Surface. All of your personal files will be deleted and your settings will be reset. All apps that you installed will be removed. For info on backing up your files, see
Back up photos, documents, and more. After a reset, you'll be able to set up Surface as if it were brand new. Make sure that you have access to the product keys and installation files for any desktop apps (for example, Microsoft Office) that you plan to reinstall
after the reset. This includes desktop apps you installed from websites, discs, or USB drives.
Step 1: Swipe in from the right edge of the screen, and tap Settings.
(If you're using a mouse, point to the upper-right corner of the screen, move the mouse pointer down, click Settings.)
Step 2: Tap or click Change PC settings.
Step 3: Tap or click Update and recovery, and then tap or click
Recovery.
Step 4: Under Remove everything and reinstall Windows, tap or click
Get started.
Step 5: Tap or click Next.
Step 6: Choose either Just remove my files or Fully clean the drive.
The option to clean the drive is more secure, but takes much longer. For example, if you are recycling your Surface, you should choose to clean the drive. If you are keeping your Surface, you just need to remove your files.
Step 7: Tap or click Reset.
Surface restarts and the Surface logo displays while the reset process completes (this can take several minutes).
Please let me know the results.
