Internet Explorer Updates: Should You Install Them If Disabled?
Should You Still Install Security Updates for a Disabled Internet Explorer?
Over time, Internet Explorer has faced criticism and many users choose to disable it on their computers. However, a valid question arises: if you've already disabled Internet Explorer, is it still necessary to install security updates for it?
The answer to this question is explored in today’s featured SuperUser Q&A. This discussion originates from SuperUser, a segment of Stack Exchange, a network of question-and-answer websites powered by its community.
The Core Issue
Maintaining security is paramount, even for software you don't actively use. Disabling a browser doesn't necessarily eliminate all potential vulnerabilities.
Security updates address weaknesses that could be exploited by malicious software. These vulnerabilities can still pose a risk, even if the browser isn't running.
Why Updates Still Matter
Even with Internet Explorer disabled, components of the browser may still be utilized by other applications. These applications could be vulnerable if the underlying Internet Explorer components are outdated.
Furthermore, some malware attempts to exploit vulnerabilities in inactive browsers. Keeping Internet Explorer updated can help mitigate this risk.
The SuperUser Response
The consensus from the SuperUser community is that installing security updates for a disabled Internet Explorer is still recommended.
Here's a breakdown of the key reasons:
- Shared Components: Other programs may rely on Internet Explorer’s core files.
- Defense in Depth: Updates provide an extra layer of security, even if the browser isn’t in use.
- Potential Exploits: Malware can target inactive browsers to gain access to your system.
Therefore, it’s best practice to continue applying security updates to Internet Explorer, even if it’s not your primary browser.

Addressing Internet Explorer Update Concerns
A SuperUser user, Stefan Surkamp, has posed a question regarding the necessity of installing updates for Internet Explorer, despite having it deactivated within the Windows Features settings.
The User's Dilemma
Stefan notes that Windows Update continues to flag security updates as available for Internet Explorer. He understands that complete uninstallation isn't possible and the browser remains present on his system.
His core concern revolves around potential security risks associated with neglecting these updates, or whether they can safely be disregarded.
Understanding the Situation
Even with Internet Explorer disabled, it's crucial to understand why updates are still offered. Several core Windows components rely on Internet Explorer's engine, regardless of whether the browser itself is actively used.
Potential Security Implications
Ignoring these updates could introduce vulnerabilities. The Internet Explorer engine is utilized by other applications and services within Windows.
Failing to patch these underlying components could potentially expose the system to security threats, even if the browser interface isn't directly accessed.
Recommended Course of Action
It is generally recommended to install the available security updates for Internet Explorer, even when disabled. This ensures that the shared components are protected.
While the risk may be lower than if actively browsing with Internet Explorer, it isn't entirely absent. Maintaining updated system components is a best practice for overall security.
In Summary
Stefan should not disregard the updates. Installing them provides a layer of security for the broader Windows operating system, mitigating potential risks associated with unpatched components that rely on the Internet Explorer engine.
Understanding Internet Explorer Updates
Insights from SuperUser contributors John and Virtlink illuminate the importance of maintaining Internet Explorer updates, even for users who prefer alternative browsers.
John's Analogy
John explains that an operating system functions much like a table. Applications, including web browsers, are items placed on this table.
Internet Explorer, however, differs in its integration. Due to Microsoft’s bundling practices, it’s physically a component of the operating system’s table itself.
The Necessity of Updates
Even infrequent Internet Explorer users should prioritize installing updates. A failure to patch known vulnerabilities can be exploited by malicious actors, escalating potential system compromises.
Furthermore, Internet Explorer serves as a rendering engine for certain browsers and applications. Utilizing these "tertiary" browsers, like Maxthon, with an outdated Internet Explorer version can lead to rendering inconsistencies.
Cost-Benefit Analysis
When considering vulnerability patches, a careful evaluation of costs and benefits is crucial. The potential disruption caused by installation and compatibility issues must be weighed against the risks associated with a successful attack.
Virtlink's Perspective
Virtlink reinforces the need to update Internet Explorer, regardless of your primary browser choice.
Internet Explorer is deeply integrated into the core functionality of Windows. Settings like proxy configurations, the hosts file, and Windows Firewall are all interconnected with Internet Explorer.
System-Wide Risk
A vulnerability within Internet Explorer can compromise the entire system. Because it cannot be uninstalled, it remains a potential entry point for attackers.
The browser can run unexpectedly, for instance, when viewing Help files (.chm). Many applications also leverage Internet Explorer to render complex content, creating further exposure.
Comprehensive System Security
Installing all available Windows updates is a proactive step towards bolstering system security. Prioritizing preventative measures is far preferable to the extensive effort of a system reinstall following a security breach.
