On July 18, 2025, Microsoft silently flicked a switch that turned off new purchases and rentals in its Movies & TV storefront, leaving longtime users with one less place to buy digital movies and shows. That quiet move capped a series of app cancellations that have systematically erased some of the most recognizable names from the Windows landscape. Internet Explorer, Paint 3D, Groove Music, and the classic Mail app all preceded it into obsolescence, each retirement a deliberate step in Microsoft’s strategy to scrap overlapping tools and funnel users into fewer, more tightly integrated experiences. The timeline is stark: Internet Explorer’s desktop app was retired on June 15, 2022; Groove Music Pass streaming ended on December 31, 2017; Paint 3D vanished from the Microsoft Store in November 2024; the Mail, Calendar, and People apps lost support on December 31, 2024; and the Movies & TV storefront locked its doors on July 18, 2025.

These aren’t random disappearances. Microsoft is pruning its product line to cut maintenance overhead, tighten security, and push harder into cloud-first, subscription-driven services. Every legacy app that gets the axe reduces the attack surface, slashes QA costs, and clears space for flagship replacements like Edge, the new Outlook, and the unified Media Player. The payoff is a leaner, more predictable Windows experience. The trade-off lands squarely on users and IT departments, who must scramble to migrate data, salvage workflows, and in some cases, fight to keep access to purchased content that suddenly feels a lot less permanent.

Internet Explorer: The Browser That Refused to Die—Until It Did

For a generation of PC users, the blue “e” icon was the internet. Bundled with Windows since 1995, Internet Explorer at its peak controlled over 90% of the browser market. But speed, security, and standards compliance gradually eroded that dominance, and by the time Chrome and Firefox had seized the crown, IE had become a liability. Microsoft ended support for the Internet Explorer 11 desktop application on June 15, 2022, pushing users to the Chromium-based Edge browser.

The death of IE doesn’t mean the death of legacy web apps, however. Edge includes an IE mode that faithfully renders sites built for older engines, and Microsoft has committed to supporting that mode until at least 2029. For enterprises still clinging to internal tools that only work in Internet Explorer, that’s a breathing room, not a permanent solution. IT administrators should inventory every critical line-of-business application that still demands IE, then either modernize the code or containerize it before the support window snaps shut. Consumers, meanwhile, can simply uninstall IE if it still lingers on their devices and switch fully to Edge, Chrome, or Firefox.

Paint 3D: The 3D Revolution That Never Arrived

When Paint 3D launched alongside the Windows 10 Fall Creators Update in 2017, Microsoft had high hopes. It was supposed to democratize 3D creation, giving hobbyists, students, and casual tinkerers a low-barrier way to build simple models, slap on textures, and remix community creations. The company even removed classic Paint from the default Windows install to nudge everyone toward the 3D future.

It didn’t work. Most users simply wanted the old, uncomplicated Paint for quick doodles and screenshot annotations. Professionals stuck with Blender and Autodesk suites. The 3D object marketplace and Mixed Reality integration that Microsoft envisioned never materialized. Come November 2024, Microsoft quietly yanked Paint 3D from the Microsoft Store and deprecated it entirely. The app will no longer receive updates, and while existing installations might still work, the official recommendation is to switch to 3D Viewer for light 3D inspection or to grab Blender for anything more ambitious. Anyone with a library of Paint 3D projects should export them immediately to standard formats like GLTF or OBJ before the app one day refuses to launch.

Movies & TV: The Storefront Shuts, Leaving DRM Anxiety in Its Wake

The Movies & TV app, first known as Xbox Video, was Microsoft’s attempt to build a digital video empire. Preloaded on Windows PCs, Xbox consoles, and once even Windows Phones, it let users buy or rent movies and shows, syncing purchases across devices. But Netflix, Amazon Prime, and a dozen other streaming services lured audiences away, and on July 18, 2025, Microsoft stopped all new purchases and rentals through the storefront. The buy and rent buttons are simply gone.

Previously purchased content, mercifully, hasn’t disappeared—yet. Users can still stream their library and download HD copies on Windows, provided they have the app. The long-term picture is murkier. DRM-protected videos remain tethered to Microsoft’s infrastructure, and if that infrastructure is ever decommissioned, access could vanish. Microsoft isn’t offering refunds or automatic migrations, though it suggests customers rebuild their libraries on services like Amazon Prime, Apple TV, or (in the US) Movies Anywhere, which can consolidate purchases from multiple vendors.

The closure is a wake-up call about digital ownership. Even when you “buy” a movie, you’re often buying a license that lasts only as long as the storefront survives. The prudent move is to download all permitted copies now, back them up on local drives, and document your library. If a title isn’t available for download, note its details and check whether Movies Anywhere or a similar service can transfer the license in your region. The lesson: never treat a single vendor’s cloud as your only copy.

Groove Music: The Streaming Service That Surrendered to Spotify

Groove Music had a long and winding road: born as Zune Music Pass, rebranded to Xbox Music, and finally renamed Groove in 2015 to match Windows 10’s aesthetic. The app sported a clean, minimalist interface and deep integration with the OS, but it could never match the catalogs, cross-platform reach, or social features of Spotify, Apple Music, or even YouTube Music. On October 2, 2017, Microsoft announced the end of Groove Music Pass streaming, effective December 31, 2017. Subscribers got prorated refunds and—in a rare, consumer-friendly twist—a partnership with Spotify that allowed them to transfer playlists and libraries almost seamlessly.

After the shutdown, Groove limped along as a local media player for owned files and OneDrive-stored tracks, but by December 2018, its Android and iOS apps were pulled. For diehard Groove users, the migration route was straightforward: accept the Spotify partnership if you streamed, or move local collections to Windows Media Player, VLC, or third-party players like Nora. The consolation is that local music playback never really died; any MP3 or FLAC collection can still be played on virtually any device. Streaming users, meanwhile, learned that platform lock-in can be broken overnight, and the ability to export playlists is a feature to value before disaster strikes.

Mail, Calendar, and People: Simplicity Sacrificed for a Unified Outlook

The classic Mail app, bundled with Windows 10 and early Windows 11, offered a lightweight, touch-friendly way to check a few inboxes without the heft of Outlook. Paired with Calendar and People, it was the minimalist’s alternative—fast, uncluttered, and perfectly adequate for everyday email. That changed with Microsoft’s “One Outlook” initiative. The company began pushing the new, web-powered Outlook client, preinstalled on Windows 11 since October 2023 and delivered to Windows 10 through updates in early 2025, as the sole email and scheduling experience. On December 31, 2024, official support for Mail, Calendar, and People ended. The apps can no longer send or receive emails.

For users who hadn’t yet switched, the clock ran out. Microsoft published step-by-step guides to export local mail, contacts, and calendar data so that nothing would be lost in the transition. The new Outlook, while more powerful and deeply integrated with Microsoft 365, struck many as a step backward in simplicity. Users who miss the old Mail app can turn to third-party clients like Thunderbird, Mailspring, or even the web versions of Gmail and Outlook.com. The key is to rescue your data immediately: if the legacy apps still launch on your device, run the export now. Once Windows removes them entirely in a future update, local data might become unrecoverable.

The Strategy Behind the Scalpel: Why Microsoft Cuts Apps

Microsoft’s app retirements aren’t capricious. They emerge from a mix of hard economics, security imperatives, and a cloud-first philosophy. Maintaining dozens of overlapping applications across a billion devices is a staggering expense. Every retired app eliminates a stream of security patches, compatibility testing, and support tickets. Consolidating around Edge, the new Outlook, and the modern Media Player lets Microsoft concentrate engineering resources on a few core products that can be updated faster and more frequently.

Security, too, improves. Older codebases accumulate vulnerabilities that hackers exploit. When Microsoft kills off an app like Internet Explorer—whose engine had become a labyrinth of legacy fixes—it immediately shrinks the attack surface. Similarly, replacing a scattered collection of media players with a single, actively maintained application reduces the number of potential entry points.

The company also knows when to concede. The Groove Music streaming service couldn’t dent Spotify’s dominance, so Microsoft partnered instead and handed users a migration path. Movies & TV’s storefront couldn’t match the content libraries of Amazon and Apple, so it was euthanized. In each case, resources that would have been wasted on a losing battle are redirected toward areas where Microsoft can win: productivity, the cloud, and AI.

The Hidden Costs: Digital Ownership and Legacy Workflows

This consolidation creates clear winners—users who embrace Microsoft 365 and its integrated ecosystem get a sleek, cohesive experience—but it also imposes significant costs. The Movies & TV shutdown crystallizes the fragility of DRM-locked purchases. When you “buy” a digital movie from a platform, you’re essentially leasing access, and the landlord can decide to stop renting. Microsoft hasn’t revoked existing purchases yet, but there is no guarantee that playback will work indefinitely. Owners of large digital video libraries on the platform now face a race to download and back up what they can, an absurd position for something they rightfully feel they own.

Enterprise IT faces its own version of this dilemma. Internet Explorer’s retirement, cushioned by Edge IE mode, only delays a harder reckoning. Internal apps built on IE-exclusive technologies like ActiveX controls will eventually need a complete rewrite or virtualization. Companies that ignore the ticking clock risk a sudden, catastrophic failure when IE mode is finally sunsetted, a disruption that could halt factory lines, financial transactions, or healthcare systems.

Even seemingly trivial apps like the old Mail client have ripple effects. Users accustomed to its simplicity are pushed into the more complex Outlook, which can feel bloated and sluggish by comparison. The loss of choice—of a lightweight tool that did one thing well—is a genuine quality-of-life downgrade for some.

Your Migration Playbook: What to Do Now

Microsoft’s retirement rhythm isn’t slowing. The only sensible response is to treat every app sunset as a prompt to audit your dependencies, export data, and test alternatives. Here is a step-by-step blueprint.

1. Inventory What You’re Losing

  • For home users: check which of the retired apps you still rely on. Did you have local emails stored in Mail? Do you launch Paint 3D for quick projects? Is your Groove Music collection still pointing to long-forgotten OneDrive tracks?
  • For IT administrators: scan domain-joined machines for legacy Internet Explorer configurations, enterprise browser extensions, and Line-of-Business applications that call IE-specific APIs. Document every dependency.

2. Export and Back Up Immediately

  • Mail/Calendar/People: use the built-in export functions to save .eml or .pst files. Copy contacts to a CSV file. Store these backups on an external drive and in a trusted cloud service.
  • Paint 3D projects: export each file to GLTF, OBJ, or FBX. If the app no longer opens, recall a Windows restore point or use a third-party viewer to extract raw mesh data.
  • Movies & TV library: for every purchased title that allows a download, transfer the HD file to a local backup. Create a spreadsheet listing titles, purchase dates, and order numbers in case future disputes arise.
  • Groove Music local files: simply ensure your music folder is backed up normally. Playlists won’t carry over unless you migrate to Spotify or export them as .m3u files.

3. Plan and Test Your Migrations

  • From IE to Edge: configure Group Policy or Intune to enable IE mode for legacy sites. Pilot this with a small user group before organization-wide rollout. Simultaneously, begin rewriting legacy web apps using modern frameworks.
  • From Mail to Outlook: install the new Outlook from the Microsoft Store and import your exported mailboxes. If you prefer a third-party client, import the .eml or .pst files there.
  • From Paint 3D to 3D Viewer/Blender: install the recommended tools and verify you can open your exported 3D models. Accept the learning curve; Blender’s documentation is extensive.
  • From Groove Music to Spotify/VLC: if you’re a streamer, use Spotify’s import tool (still available to former Groove users). For local files, set VLC or Windows Media Player as your default and rebuild any playlists manually.

4. Fortify Against Future Shock

  • Treat all digital purchases as temporary licenses. Diversify your library across multiple providers linked through Movies Anywhere (U.S. only) or similar aggregators.
  • Keep local backups of everything you truly value—emails, documents, music, and videos—in formats not controlled by a single vendor.
  • Subscribe to Microsoft’s Message Center if you’re an IT admin; end-of-life dates are announced there first.

Looking Ahead: A Leaner Windows, but at What Price?

Microsoft’s app retirement playbook is clear: sunset overlapping services, migrate users to consolidated flagship products, and absorb the blowback. For most consumers, the change will be subtle. They’ll use Edge, Outlook, and the new Media Player without ever missing the old guard. For power users and enterprises, the friction is real, but manageable with early action.

The uncomfortable truth is that Microsoft’s incentives align with control and recurring revenue, not with preserving every little tool that a segment of users loves. As more apps go the way of IE and Paint 3D, the onus falls on users to stay informed, maintain backups, and treat platform transitions as routine maintenance—not crises to be weathered at the last minute. The next Windows update might retire another familiar utility. Be ready.
