 If a Windows 10 upgrade is not successful, it can be very helpful to understand *when* an error occurred in the upgrade process. 
 
-Briefly, the upgrade process consists of four phases: **Downlevel**, **SafeOS**, **First boot**, and **Second boot**. The computer will reboot once between each phase. 
+Briefly, the upgrade process consists of four phases: **Downlevel**, **SafeOS**, **First boot**, and **Second boot**. The computer will reboot once between each phase. Note: Progress is tracked in the registry during the upgrade process using the following key: **HKLM\System\Setup\mosetup\volatile\SetupProgress**. This key is volatile and only present during the upgrade process; it contains a binary value in the range 0-100.
 
 These phases are explained in greater detail [below](#the-windows-10-upgrade-process). First, let's summarize the actions performed during each phase because this affects the type of errors that can be encountered.

 >**Windows 10 LTSC/LTSB**: Due to [naming changes](https://docs.microsoft.com/windows/deployment/update/waas-overview#naming-changes), product versions that display Windows 10 LTSB will be replaced with Windows 10 LTSC in subsequent feature updates. The term LTSC is used here to refer to all long term servicing versions.
 
->In-place upgrade from Windows 7, Windows 8.1, or Windows 10 semi-annual channel to Windows 10 LTSC is not supported.  **Note**: Windows 10 LTSC 2015 did not block this upgrade path.  This was corrected in the Windows 10 LTSC 2016 release, which will now only allow data-only and clean install options. You can upgrade from Windows 10 LTSC to Windows 10 semi-annual channel, provided that 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.
