Microsoft Phases Out SmartScreen in Internet Explorer and IE Mode
In a significant move towards modern security, Microsoft has officially announced the deprecation of the SmartScreen feature within Internet Explorer (IE) and IE Mode on Windows 11. This change was introduced with the latest Windows update, aligning with the company’s commitment to enhance security measures and phase out outdated components. It is essential to clarify that this alteration impacts only the functionalities within Internet Explorer and IE Mode on Windows 11, leaving SmartScreen operational in Microsoft Edge, the Windows Shell, and previous versions of the Windows operating system.
Context of SmartScreen Deprecation
As Internet Explorer has already been phased out on Windows 11—redirecting users to Microsoft Edge upon access—this deprecation may seem less impactful. Nevertheless, IE Mode continues to be supported for legacy enterprise applications. Users of IE Mode will notice the differentiation, as it remains a specialized environment intended primarily for trusted intranet sites, rather than general web browsing.
Rationale Behind the Decision
The reason for this deprecation lies in Microsoft’s goal of security modernization, as well as the limited use case of IE Mode. SmartScreen, which serves as an anti-phishing tool, is deemed redundant when many enterprise administrators specifically configure trusted site lists for IE Mode. Thus, retaining SmartScreen in this context is unnecessary. Moreover, retiring SmartScreen allows for the removal of older binary components associated with its infrastructure, simplifying and modernizing the system.
Continuing Protection for Users
While SmartScreen is being phased out, Windows 11 users are not left vulnerable. They continue to benefit from robust system-level protections offered by Windows Defender and Microsoft Defender for Endpoint, ensuring comprehensive safeguards against system threats.
Recommendations for Administrators
Given the recent changes, Microsoft has provided specific recommendations for administrators. It is crucial to note that IE Mode should not be employed for navigating untrusted public internet sites. Administrators are urged to limit its functionality by restricting access to trusted, internal enterprise applications through carefully curated site lists. For safe web browsing, Microsoft strongly advocates the use of its latest Edge browser.
Adjusting SmartScreen Settings
For those facing issues post-update, disabling SmartScreen in IE Mode can be accomplished through the Internet Options. To do this, navigate to Start, enter ‘internet options’ in the search field, and select Internet Options. Proceed to the Security tab, choose Trusted Sites, and select Custom Level. There, under ‘Use Windows Defender SmartScreen, ’ opt for Disable, followed by clicking OK.
