Windows 10 starts to auto-block unwanted apps (PUAs)

Microsoft introduced the 'potentially unwanted app' (PUA) blocking setting in Windows security with the introduction of the Windows 10 May 2020 update. Starting this month, the security feature, enforced by Microsoft Defender and Microsoft Edge, will be turned on by default. A support bulletin published by Microsoft earlier this week, spotted by Bleeping Computer, discusses the change, framing it as a move to increase security and system reliability.
