I have a brand new PC with Windows 10 and since the last month, I receive error messages about the 1709 update. The error code is 0xc1900200 which means that "machine does not meet the minimum system requirements."

This morning, the error message was a bit clearer:

you can't install windows on a usb flash drive using setup

Since I moved the OS from a HHD to a M.2 SSD drive, is it possible that windows consider it as a USB drive? If so, how can I let him know it's ok to install the 1709 update on it?

Windows does not allow portable installations of Windows to be updated. This includes the installation of feature updates.

Follow these steps to delete the Windows To Go registry value:

  • Open regedit.exe
  • Browse to:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
    
  • Delete this value: PortableOperatingSystem

After the removal of the key Windows will allow you to perform the upgrade.

Additional information:

To change the PortableOperatingSystem registry, follow these steps:

  1. Open Registry editor (regedit.exe)
  2. Locate and the select the following registry subkey:

     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
    
  3. From the right-side pane double-click on PortableOperatingSystem Dword value

  4. Change the value data to 0 (The default value is 1)
  5. Close the registry editor
  6. Restart the computer
