When I miss at least one cumulative update on one of my Windows 10 or Windows Server 2019 installations I often get the situation that after installing seemingly all pending updates and rebooting first the Windows Update GUI says the system is up to date but as soon as I click the check for updates button it finds a whole bunch of further updates. I can install these right away without issues but that really is annoying and time consuming and also requires a second reboot right after the first one...
Is there a way to force Windows to check for all missing updates directly and force it to install them all at once?
Hitting the check for updates button manually at first (if it even is available) or
wuauclt.exe /detectnow doesn't cut it. But maybe there is a way with PowerShell or something similar?
(I'm assuming this is already answered somewhere out there but searching for it really seems hard since tons of other Windows Update topics pop up. But I'd also be grateful for any link or reference.)
