You can download the updates for the Windows Store apps from the Windows Update Catalog<sup>1</sup> and install them offline using System Center, WSUS, or other deployment tools. However, this method only works for the apps that are distributed with Windows 11/10 editions, not for third-party apps.
You can use a tool like Ninite<sup>2</sup> to install or update multiple apps at once. Ninite can create a custom installer that you can run on your standalone network. Ninite supports many popular apps, such as Chrome, VLC, Skype, etc.
You can use the Windows Package Manager (winget) command-line tool<sup>3</sup> to update one or all your apps with a single command. Winget can also create a manifest file that you can use to install or update apps on another machine. Winget requires Windows 11 or Windows 10 version 1709 or higher.
I hope this helps you find a suitable solution for your situation.
