The 1809 update has been postponed once more. You're using Windows 10 1803 on a mid-2012 MacBook Pro.

Reinstalling things won't help here since it could ruin BootCamp.
It seems you haven't used Boot Camp recently, so the outcome might be similar to a standard Windows Update install. The ISO will work in Windows and should behave like a regular update.
Block placements are being made for those without compatible systems. Ensure all your software and drivers—such as printer, keyboard, mouse, etc.—are current. If an update is still missing, your system isn’t ready for 1809; you’ll need to wait longer. Forcing the update could cause problems during or after the upgrade.
