Should I Delete Internet Explorer?

When It Makes Sense

• Good fit: You use only modern websites and cloud services that work in current browsers such as Microsoft Edge, Google Chrome, or Mozilla Firefox. If your daily browsing, banking, email, and streaming all function without Internet Explorer, there is little reason to keep the older browser active. Removing or disabling it reduces the chance that you or someone else on the computer will accidentally open a discontinued browser that no longer receives security updates.
• Good fit: You are running Windows 10 or Windows 11 with the latest updates and Microsoft Edge installed. Microsoft ended support for the Internet Explorer 11 desktop application on June 15, 2022, for most supported versions of Windows 10. Windows 11 does not include the standalone Internet Explorer application at all. On these systems, the safest course is to use Edge as your default browser and rely on Internet Explorer mode only when a specific site requires it.

When You Should Avoid It

• Warning sign: You rely on older business applications, government portals, banking sites, or internal intranet pages that explicitly require Internet Explorer. Some legacy systems use ActiveX controls, older Java versions, or document modes that only render correctly in the Internet Explorer engine. Deleting or fully disabling IE on such systems can lock you out of tools you need for work. In organizational environments, you should consult your IT department before making any change.
• Warning sign: You are using an older version of Windows where Internet Explorer is embedded in the operating system. On certain editions of Windows 8.1, Windows 7, or older server versions, removing the browser is either unsupported or may remove components that other programs expect to find. Attempting to delete system files manually can cause Windows Update, help systems, or built-in wizards to behave unpredictably. In these cases, disabling IE through official Windows features is safer than trying to uninstall it completely.

Pros and Cons

Pros

• Reduced security exposure. Because Microsoft no longer updates the standalone Internet Explorer application with new features or routine security patches, keeping it available increases the chance that a user might visit a malicious site with an unprotected browser. Moving to a modern browser that receives regular updates closes that pathway and reduces your overall attack surface.
• Cleaner user experience and easier maintenance. A single modern browser means fewer bookmarks, fewer settings panels, and less confusion about which icon to click. For family members or less technical users, removing the blue “e” icon helps prevent them from falling back to an outdated browser out of habit.

Cons

• Legacy compatibility breakage. The biggest drawback is that some websites and internal tools still rely on the Trident rendering engine used by Internet Explorer. If you delete or disable IE without testing your critical sites first, you may suddenly lose access to payroll systems, medical records portals, manufacturing dashboards, or government filing tools.
• Limited or risky removal options. On many versions of Windows, Internet Explorer cannot be completely uninstalled like a normal application because parts of it are integrated into the operating system. Turning it off through “Turn Windows features on or off” is usually reversible, but it may still affect programs that quietly depend on IE components, such as older versions of Microsoft Office or certain setup wizards.

Decision Checklist

• Do any websites, web apps, or work tools I use still require Internet Explorer? Check with your employer, bank, school, or software vendor before removing the browser. If the answer is yes, plan to use Microsoft Edge with IE mode rather than deleting the older engine entirely.
• Which version of Windows am I running, and is Internet Explorer a removable feature? On Windows 11, the standalone app is already gone. On Windows 10, you can usually disable it through optional features. On older systems, removal may be risky or unsupported, so research your exact edition first.
• Have I tested all critical sites in a modern browser or in Edge IE mode? Before disabling IE, open every important site in Microsoft Edge and confirm it loads, prints, saves passwords, and handles forms correctly. This reduces the chance of a last-minute surprise after the change is made.

Alternatives to Consider

The best alternative for most users is to keep Microsoft Edge as the default browser and enable Internet Explorer mode only for the specific sites that need it. IE mode uses the older IE engine inside the modern Edge browser, giving you backward compatibility without exposing your everyday browsing to an unsupported application. Other modern browsers, such as Google Chrome or Mozilla Firefox, are excellent choices for general use but cannot run ActiveX or IE-only sites. If you manage a business environment, consider running legacy applications inside a virtual machine or a Remote Desktop session so that the rest of the computer can use a fully updated browser. For organizations with strict compliance needs, a managed browser policy from your IT department is usually preferable to manually deleting software.

Final Recommendation

For most home users, the right move is not to “delete” Internet Explorer by force, but to stop using it and switch to a modern, supported browser such as Microsoft Edge. If you have no legacy sites to worry about, you can safely disable IE through Windows optional features. If you do rely on older applications, use Edge with IE mode instead of removing the underlying compatibility layer. Business and government users should involve their IT support team before changing browser configuration, because compatibility issues can affect payroll, record keeping, or regulatory workflows. When in doubt, test first, change gradually, and seek expert guidance for high-stakes environments.
