Microsoft has announced that Potentially Unwanted App Blocking will now be enabled by default on all Windows 10 devices. This security feature officially debuted with last year's Windows 10 May 2020 Update. Now, any PC running Windows 10 in a version no older than last year's May update will automatically block potentially unwanted apps without any user intervention.
Previously, users had to manually activate this feature on their devices in the settings. Microsoft noted that the change will take effect in early August.
The company also explained:
“In the Windows 10 May 2020 Update, we added Potentially Unwanted App Blocker for everyone using Windows 10, but customers who wanted to use it still had to turn it on. Starting in early August 2021, we will start enabling it by default to make it easier for you to maintain peak performance. If you want to disable or re-enable the setting for any reason, you can do this by going to the "Windows Security" application> "Application and browser management"> "Reputation-based protection settings".
