How does this app work?
winstall is powered by Windows Package Manager (aka "winget"), Microsoft's new package manager for Windows 10. Windows Package Manager is currently in preview, and it is not available by default in Windows 10.
Installing Windows Package Manager
If you don't already have Windows Package Manager, you can install it by downloading and installing the latest .appxbundle file from here.
To use winstall, you can search for apps on the homepage. Additionally, you can also view all the apps available via Windows Package Manager on this page.
Simply select the apps you want to download and click on the "Generate Script" button at the bottom of the screen. You will then be presented with a command that you can copy and paste into any Windows command-line. Input that into a command line app of your choice, and hit enter to start installing the apps one-by-one using Windows Package Manager. You can also generate a PowerShell script by toggling the "Show Powershell scirpt" option.
Alternatively, you can click on the "Download .bat/.ps1" button which will download a batch file. However, you will likely get a security warning from your browser. In that case, ignore the warning as the batch file is completely secure. Once downloaded, you can double-click the .bat/ file to install the apps using the Windows Package Manager.
How is the data obtained?
winstall is powered by an API that I have built. The API regularly checks Microsoft's official repository for Windows Package Manager apps. This means it always provides the latest data.
The API updates its data every 15 minutes on weekdays, and every 3 hours on weekends. I will be making the API open-source in the near-future.
