 With a Node.js runtime bundled, DeskGap comes with support for npm packages and all the battle-tested __native capabilities__ in Node.js such as [`fs`](https://nodejs.org/api/fs.html), [`net`](https://nodejs.org/api/net.html), [`http`](https://nodejs.org/api/http.html). The price is a __larger executable size__ (about 8 MB zipped and 20 MB unzipped).
 
-### Why is the supported version of Windows so high? Any plan of supporting Windows 7?
-
-Older Windows’ __do not have a modern browser engine__, only the one that powers Internet Explorer. Windows 10 1809 is the first version that provides a modern webview with [enough functionalities](https://docs.microsoft.com/en-us/microsoft-edge/dev-guide#win32-webview-updates) for DeskGap to be possible.
-
-To support Windows 7, app developers would have to face compatibility issues coming from as low as IE 8. I personally don’t have enough motivation and interest to do this, but pull requests are always welcome.
-
-If you want to try DeskGap but dropping Windows 7 support is a no-go for your app, consider packaging the app with Electron for the unsupported platform. The DeskGap API is intentionally designed to be like Electron’s. The following code is a good start:
-
-```js
-let appEngine;
-try {
-  appEngine = require('deskgap');
-}
-catch (e) {
-  appEngine = require('electron');
-}
-const { app, BrowserWindow } = appEngine;
-```

-### So I can port my Electron app to DeskGap?
+### Can I port my Electron app to DeskGap without much modification?
 
 Probably no. The DeskGap API is still quite limited. If you start building an app with DeskGap, getting it running on Electron may be easy, but not the other way around.
