Windows 11’s best new feature comes with a big catch

Windows 11 is getting a major security boost – but you may not want it.

Microsoft has announced a powerful new feature for Windows 11 that can protect users from malicious apps and downloads. The Smart App Control feature aims to keep your PC protected from malicious apps, and as PC World reports, this “major enhancement to the Windows 11 security model,” as Microsoft calls it, will be baked into Windows 11, with every new app you run checked to see if it may be a virus – or worse.

It appears to be based on similar tech to

SmartScreen, which is included in the Edge web browser.

This increased level of threat protection is great to have, and will be of particular use to businesses and enterprises that want to ensure their devices are protected. However, it comes with a pretty big caveat: existing Windows 11 users will need to reinstall Windows 11 completely. This means wiping your entire PC and starting again, and that could be a real pain for many users.
