You can upgrade from Windows 10 LTSC to Windows 10 General Availability Channel if you upgrade to the same or a newer build version. For example, Windows 10 Enterprise 2016 LTSB can be upgraded to Windows 10 Enterprise version 1607 or later. Upgrade is supported using the in-place upgrade process (using Windows setup). You'll need to use the Product Key switch if you want to keep your apps. If you don't use the switch, the option Keep personal files and apps option is grayed out. The command line would be setup.exe /pkey xxxxx-xxxxx-xxxxx-xxxxx-xxxxx, using your relevant Windows 10 GA Channel product key. For example, if using a KMS, the command line would be setup.exe /pkey NPPR9-FWDCX-D2C8J-H872K-2YT43.
Before a pkey can be used, it must first be allocated withpkey_alloc(). An application calls the WRPKRU instructiondirectly in order to change access permissions to memory coveredwith a key. In this example WRPKRU is wrapped by a C functioncalled pkey_set().
