Microsoft has fully discontinued Internet Explorer, its once-dominant web browser, after nearly three decades of service. The company retired the software in 2022, shifting all efforts to Microsoft Edge amid growing concerns over security, speed, and modern web needs.
This move marks the end of an era for a browser that shaped early internet use but fell behind rivals. Users now face a landscape where Edge takes center stage, offering better tools and protection.
A Brief History of Internet Explorer
Internet Explorer first appeared in 1995 as part of Windows 95, quickly becoming the go-to browser for millions. It peaked with over 90 percent market share in the early 2000s, bundled with Windows operating systems.
Over time, competition heated up. Browsers like Firefox in 2004 and Google Chrome in 2008 introduced faster loading and better features, chipping away at IE’s dominance.
By 2015, Microsoft launched Edge as a fresh start, but IE lingered on older systems. Full retirement came in June 2022, ending support for IE 11, the final version.
This timeline shows how IE went from essential to outdated in a fast-changing digital world.
Key Reasons for the Discontinuation
Internet Explorer struggled with persistent issues that made it unreliable for modern users. Its code base grew outdated, leading to slow performance and frequent crashes.
Security flaws were a major problem. Hackers exploited vulnerabilities, putting users at risk of malware and data breaches.
IE also lagged in supporting new web standards, frustrating developers and users who needed smooth experiences on sites with advanced features.
Competition played a big role too. Rivals like Chrome offered quicker updates and better privacy tools, drawing away IE’s audience.
In the end, Microsoft saw no path forward for maintaining two browsers, choosing to consolidate resources.
Here are the main factors that led to IE’s end:
- Outdated technology that couldn’t match modern web demands
- High vulnerability to cyber threats and exploits
- Poor performance compared to faster alternatives
- Loss of market share to innovative competitors
The Shift to Microsoft Edge
Microsoft introduced Edge in 2015 with Windows 10, aiming for a cleaner, faster browsing experience. A major upgrade in 2020 switched it to the Chromium engine, the same one powering Chrome.
This change brought big improvements. Edge now loads pages quicker, uses less memory, and integrates seamlessly with Windows features.
Users gain access to extensions from the Chrome Web Store, built-in tools like a PDF editor, and enhanced privacy settings. Regular updates keep it secure and feature-rich.
Microsoft promotes Edge as the default on Windows 11, even popping up messages to switch from other browsers. This focus ensures one strong product instead of splitting efforts.
Recent Security Concerns in 2025
In August 2025, new threats emerged targeting IE’s old JavaScript engine, known as Chakra. Attackers used zero-day exploits to trick users into visiting fake sites and gain device access.
Microsoft responded quickly by restricting IE mode in Edge, a feature that lets users access legacy sites. This mode, meant for compatibility, exposed risks in an engine not built for today’s defenses.
The company now limits access to pre-approved sites in IE mode, urging full transitions to modern browsing. These events highlight why IE’s retirement was crucial.
Experts note that while IE mode remains supported until at least 2029, users should minimize its use to avoid vulnerabilities.
| Feature | Internet Explorer | Microsoft Edge |
|---|---|---|
| Launch Year | 1995 | 2015 (Chromium update in 2020) |
| Engine | Trident | Chromium |
| Security | Frequent vulnerabilities | Built-in defenses and regular patches |
| Speed | Often slow and buggy | Fast loading with efficient resource use |
| Modern Support | Limited web standards | Full compatibility with latest tech |
| Updates | Ended in 2022 | Ongoing and frequent |
Impact on Users and Businesses
Many users barely noticed IE’s exit, as most had switched years ago. For those on older systems, Microsoft redirects IE attempts to Edge automatically.
Businesses faced bigger challenges. Some relied on IE for internal tools built around its quirks, leading to a scramble for updates.
Government agencies and companies with legacy software invested in migrations to Edge’s IE mode. This ensured continuity without the old risks.
Overall, the shift has pushed better online habits, with users enjoying safer, smoother experiences.
What the Future Holds for Web Browsing
Microsoft plans to support Edge on Windows 10 until 2028, even as that OS nears its end. IE mode in Edge gets backing through 2029, with advance notice for any changes.
The company invests heavily in Edge features, like AI tools for smarter searches and immersive reading modes. This positions it as a strong rival to Chrome and others.
As web threats evolve, focusing on one secure browser makes sense. Users benefit from innovation without the baggage of outdated tech.
In a world of constant digital change, Microsoft’s decision clears the way for progress.
