The installer is gone.
Ship the app to Windows 11 anyway.

Forge captures the application from the machine where it already runs and builds a signed MSIX, App Attach, IntuneWin or MSI. Do it yourself, from the CLI, or let your AI agent do it.

Every company has one.

No vendor. No installer. And Windows 10 has ended.

But it still has to run.

Forge captures it from the PC where it still runs, in the app, from the command line or with your AI agent.

One signed MSIX, validated and tested.

The same app, on Windows 11 and Server 2025.

The old PC can finally retire.

We tested Forge on 3,261 app cases.

More than nine in ten built an MSIX.

Windows 10 support ended. Which apps are still holding you back?

Microsoft ended Windows 10 support on 14 October 2025. The applications blocking the move to Windows 11, Intune and AVD tend to be the same three kinds.

  • The problem

    Nobody can find the installer


    With Forge

    Capture it from the machine where it runs: files, registry, AppData, services and dependencies.

  • The problem

    An estate of App-V packages


    With Forge

    Convert straight to MSIX or MSI, no resequencing. App-V server is supported to October 2029, so you set the pace.

  • The problem

    MSIX skills on the team are thin


    With Forge

    AI guidance explains each packaging decision and fix-up, and the free course gets the team certified.

Moving off App-V? Convert, do not resequence.

Forge converts an existing App-V package straight to MSIX or MSI, with no resequencing and no original installer. The App-V server is in fixed extended support until 9 October 2029, so you set the pace.

Still resequencing App-V?

Moving off App-V usually means doing every package again.

Forge extracts the App-V package, then builds the MSIX. No resequencing, no installer.

Script it, and convert the whole estate.

Signed, validated and ready for the platforms you already run.

No panic. App-V server support runs to 2029.

Convert your first one free. No card.

Will Forge package your apps? We tested 3,261 first.

Forge's automated workflow built an MSIX for 90.68% of 3,261 Windows application cases, across eight installer types. Your estate is not our sample, so the honest next step is to run your own applications through it, free.

Applications came from catalogue searches, not a random sample. A smoke test is a first check, not proof of production readiness. Preprint, not yet peer reviewed; EfficientEther builds Forge and declares that interest.

Agentic packaging. Let AI do the packaging.

Forge ships an MCP server, so Claude Code, Claude Desktop, Cursor or the agent you already use can capture, package, sign and validate through Forge. It runs on your machine, uses your certificate, and asks before it acts.

Before you start

Do I need the original installer?

No. Forge captures from running Windows systems, so you can package applications when the installer is missing, incomplete or no longer usable.

Is the trial really free, with no card?

Yes. The trial gives you the full product for 7 days, with 25 captures: the GUI, PowerShell module, CLI and MCP server. You sign up with your work email. There is no credit card and no sales call. Trial captures are for evaluation, not production use.

Is the training free even if I never buy?

Yes. The course, the final exam and the certificate are free for every account, whether or not you buy Forge. The certificate lasts 12 months, and renewing it is free: you answer the exam questions again, without repeating the lessons.

Which Windows versions can I capture from?

Any version from Windows XP SP3 to Windows 11. The capture agent is a single portable executable with no installer or runtime prerequisites, so it runs on the machine where the application already lives. Building and signing the MSIX then happens on Windows 10 (version 1709 or later) or Windows 11.

Does App Attach work with Windows 365 or Intune?

No. Windows 365 and Intune do not support App Attach, so Cloud PCs and Intune-managed devices get MSIX or IntuneWin from the same capture. App Attach is the delivery format for Azure Virtual Desktop and other session-host platforms.

What happens when the trial ends?

Nothing is charged, because we never took a card. Forge needs a licence key to keep capturing and packaging: a full licence is £895 per admin user per year plus VAT, by card, on Azure Marketplace or through a partner. Your account, the training and your certificate stay free. If you need longer to finish an evaluation, email info@efficientether.co.uk.
