Preventing installation of bloatware in Windows 10. Microsoft is currently testing a new feature which will allow Windows 10 users to only install apps from the Windows Store — preventing them from installing the classic Win32 apps. Once enabled, users will see a warning whenever they try to install a Win32 app — they will get a dialog saying apps from the Windows Store helps to keep their PC “safe and reliable.”

This feature is disabled by default, but users can enable it really easily if they want. Microsoft offers two different options for the feature: you can completely prevent installation of Win32 apps, or you can allow users to install them anyway from the dialog.

It will help Microsoft prevent installation of bloatware and malware on Windows 10 PCs. Not being able to install Win32 apps is going to keep the PCs of novice users safe, as they are less likely to install malware on their PCs. And the Windows Store has apps that will meet their needs for the most part, and they can also get some Win32 apps from the Windows Store thanks to Microsoft’s Desktop App Converter.

Microsoft is also working on a new Windows 10 Cloud that will completely prevent users from installing the Win32 apps.
