    Hi Guys,

    I tried again with the in-place upgrade, but still kept getting the reserved space - the install popped-up a few extra steps that weren't shown in the tutorial listed, above.

    So I went back to a clean 1903 - I guess I'll have to wait until a guru figures out a way to turn it off.

    However, I did notice that after I'd got my 1903 install fully configured (all metro apps and Windows app-store GONE and all my programs installed), and I used Acronis True Image to create an image backup, the resultant .TIB backup file was around 2GB smaller than a clean 1809 install (same programs and config).

    So it looks like the reserved space doesn't actually cause much of an issue.

    You can set the Reserved storage to be disabled by default by applying the registry tweak to the offline install.wim.

    dism /Mount-Image /ImageFile:C:\OFFLINE\install.wim /Name:"Windows 10 Pro" /MountDir:C:\OFFLINE\mount
    reg load HKLM\OFFLINE C:\OFFLINE\mount\Windows\System32\Config\Software
    reg add "HKEY_LOCAL_MACHINE\OFFLINE\Microsoft\Windows\CurrentVersion\ReserveManager" /v ShippedWithReserves /t REG_DWORD /d 0 /f
    reg unload HKLM\OFFLINE
    dism /Unmount-Image /MountDir:C:\OFFLINE\mount /Commit /CheckIntegrity
