Decide your packaging format, delivery route and sourcing model on evidence, not on vendor claims.
Application packaging budgets are usually set from last year's supplier quote and a vendor's promise of effort savings. Neither tells you how many of your applications will actually package, install and run as MSIX, what the platform underneath has changed, or whether building the capability in-house pays back at your volume. Windows 10 has passed end of support, Windows 11 servicing is removing components old install scripts depend on, and the question of whether MSIX is ready now has measured answers.
The 2026 edition replaces assertion with evidence. It summarises three open-access EfficientEther research preprints: automated MSIX packaging across 3,261 application cases (90.68% produced a package, 80.04% passed a complete smoke test), the native MSIX or App Attach decision for Azure Virtual Desktop, and a defensive security analysis of the Package Support Framework. Measured results are kept separate from modelled ones, and every assumption in the cost model is stated so you can substitute your own figures.
It also updates the market picture: what Microsoft has invested in the MSIX platform over the past year and where the tooling gaps remain, published UK public-sector packaging prices and day rates, how packaging services describe MSIX to the organisations that hire them, how to govern AI in packaging work, and an in-house versus outsourced cost model. It closes with a seven-step decision framework and six actions for the next 90 days.
CIOs, CTOs and end-user computing leads setting packaging strategy, packaging and endpoint teams planning an MSIX move, MSPs pricing packaging services, and procurement teams comparing quotes. It suits estates of any size; the cost model is worked at 100 packages a year and shows where the answer changes.

Plan, package, test, and move Windows applications into production with clear ownership.
Windows and Office CVEs rose 159.1% in the latest complete year, to 2,438, while browsers and developer tools moved to faster release cycles. A 36-month descriptive study of what that means for patching and packaging teams.
Measured on 15,880 WinGet packages and 50 popular products: 56.9% install through a setup-engine EXE, 16.6% through an MSI and 1.6% are MSIX or APPX. What that means for teams planning a move to Windows 365, Azure Virtual Desktop or Intune.
