I have an old system running Windows 10 2016 LTSB Enterprise, and i would like to bring it to the current version of Windows.
In the beginning, i thought that a Windows Update run should be enough, but it isn’t.
Infact, Windows Update, will bring the system to the last 2016 LTSB version: 1809.

So, what do you need to update your system?
A Windows 2019 LTSC ISO!
And where can you find it?

So now follow these steps:
Mount the iso
Mount the iso simply clicking on the right button of the mouse over the iso selecting “Mount”.
Run the installer
Open the Virtual CDROM, and run the installer




Bluetooth driver
During the upgrade process, the setup fails, telling me that i have to update the bluetooth driver first. So follow the link and install the driver. This step it’s not necessary if you don’t have any conflictual driver



After the update, you will have to reboot your system and restart the installation process.
The installation starts


After some minutes, the system will restart and you will see this


After the installation you will have a Windows 10 LTSC. Now it’s time to run again Windows Update! Yeah!


After the reboot, you will have to relaunch Windows Update again!

After installing the KB4559003, your system will be updated (as today 28/07/2020).
The end

No errors?
I’m consistently getting either

We’ve set your PC back to the way to was right before you started installing Windows 10.
0xc1900101 – 0x20017
The installation failed in the SAFE_OS phase with an error during BOOT operation.
Or
We couldn’t install Windows 10

This is upgrading the Windows 10 Enterprise LTSB 2016 (1607) to Windows 10 Enterprise LTSC 2019 (1809).
Seeing this issue on multiple different machines (different images that were build around the same time).
on which phase did you get these errors?
Quindi, se ho capito bene, non si tratta solo di inserire il nuovo product key, ma viene installato un sistema operativo nuovo… corretto?
si, ci viene installato sopra praticamente
