Windows Startup Launch Parameter

So a recent Windows update apparently screwed up the registry location on my computer that handles certain startup programs with windows, including 1Password
(HKCU\Software\Microsoft\Windows\CurrentVersion\Run) specifically (The entries in the registry are gone, so it's not like they even show up in Task Manager as disabled. )

I can make it start up with windows again by putting a shortcut in the Windows startup folder, but it doesn't start minimized. And I can't figure out the parameter to start it minimized.

So main question:
What's the command line argument to start 1Password minimized in Windows?

I've tried the usual suspects like -minimized, /minimized, etc.
