The PCs where I'm working do not have internet access as they contain sensitive data and are only connected to their VPN sites, and I do not want to connect the PCs to the internet for security purposes. Is there a safe offline installer for Windows?

I'd like to upgrade to Windows 10, 22H2 from Windows 10, 1909

Yes, there are several ways this can be done. One of them is to simply use the Media Creation tool. That should provide the option to update on that machine if you plugin said Media.

  • Media Creation Tool requires an Internet connection

  • Every option requires an internet connection eventually short of buying retail media. He won't be able to run it on the target machien but preparing a USB Key or installation DVD on a different computer that has internet works and it can be used to update said machines.

Do a Repair Install of Windows 10 with an In-place Upgrade.

Download the latest ISO from Microsoft's page for Download Windows 10, then do the In-place Upgrade by executing the Setup executable from the ISO.

You may also download individual updates from the Microsoft Update Catalog for Windows 10 and install each one individually by executing the downloaded file.

  • Feature updates like 22H2 cannot be found on the Windows Update Catalog website , in other words, they cannot be downloaded separately and must be installed through the appropriate Windows ISO

  • @Ramhound: Yes, indeed. To clarify my answer : The Windows Update Catalog is only for updates that will arrive after the feature update.
