October 14, 2025 marks the official end of support for Windows 10. While Microsoft will offer Extended Security Updates (ESU), they’re costly, temporary, and don’t solve the underlying problem: countless business-critical applications still run on WinForms and the .NET Framework.
For many organizations, these applications are the backbone of operations — managing workflows in finance, healthcare, government, manufacturing, and beyond. The challenge is clear: how do you keep these apps alive, secure, and future-proof without embarking on a risky multi-year rewrite?
As of August 2025, 45% of Windows desktops still run Windows 10.
Millions of internal line-of-business apps depend on Windows Forms.
Many PCs won’t meet Windows 11 hardware requirements, leaving enterprises with stranded fleets and unsupported apps.
This isn’t just a technical problem — it’s a compliance, security, and business continuity risk.
Enterprises usually explore three routes:
Stabilize:
Upgrade to WinForms on modern .NET (8/9), keep the desktop experience, and ensure compliance.
Bridge:
Run legacy apps inside virtualized environments like Azure Virtual Desktop or Windows 365.
Evolve:
Move WinForms applications to the web — enabling browser-based access, cloud hosting, and multi-tenant delivery.
Each has trade-offs. Stabilization keeps things familiar but doesn’t deliver new business value. Virtualization buys time but locks in technical debt. The real opportunity lies in evolving.
Wisej.NET is purpose-built for organizations that want to evolve their WinForms apps quickly, securely, and with minimal disruption:
True web apps, familiar coding model: Developers write in C# or VB.NET, keeping the same event-driven model as WinForms.
Pixel-perfect migration: Complex WinForms UIs with grids, menus, MDI layouts, and reporting migrate without a full rewrite.
Cross-platform reach: Apps run in any modern browser, on any device — desktop, tablet, or mobile.
Future-proof stack: Built on HTML5, CSS, and JavaScript, without requiring teams to become front-end specialists.
In short, Wisej.NET lets teams modernize without starting over.
We recommend organizations start small:
Select 1–2 high-impact forms (for example, a reporting dashboard or data entry screen).
Re-platform them with Wisej.NET in just a few weeks.
Demonstrate security, performance, and remote access advantages to stakeholders.
From there, you can scale confidently — at your own pace.
The countdown to Windows 10 end of support is on. If your business still depends on WinForms apps, the time to act is now. Whether you stabilize, bridge, or evolve, the wise path is to unlock the value of your existing investments without endless rewrites.
