Windows 10 End of Support Is Here. Move to Windows 11 with PCmover Enterprise—Today.

Windows 10 EOS • October 14, 2025

TL;DR for ITDMs: Windows 10 support ended October 14, 2025. Unsupported OSs stop getting monthly security fixes, increasing breach and downtime risk. Microsoft 365 Apps support on Windows 10 ended the same day (with security updates through October 10, 2028 only to ease transition). PCmover Enterprise migrates applications, profiles, settings, and files to Windows 11 at scale—cutting cutover time, reducing help desk tickets, and saving $300+ per PC in labor versus rebuilds (per Laplink case studies). See sources.

Why this matters—today

Per Microsoft’s lifecycle guidance, Windows 10 (version 22H2, all editions) reached end of support on October 14, 2025—no more monthly security updates outside ESU options for organizations. Microsoft also confirms that Microsoft 365 Apps are no longer supported on Windows 10, with security updates on Windows 10 provided until October 10, 2028 to help IT teams finish migrations.

Despite the deadline, the installed base is still significant: recent desktop telemetry shows Windows 10 hovering around the ~41% mark of Windows desktops going into the deadline, with Windows 11 just under half. Analyst research estimates roughly 550 million corporate PCs globally, and about half of those won’t meet the Windows 11 deadline—meaning many enterprises still have work to do.

What happens if we delay?

• Growing attack surface: Unsupported OSs don’t receive security patches. Verizon’s latest DBIR highlights a significant year-over-year increase in vulnerability exploitation as an initial access vector.
• Operational risk proven by history: When organizations lag on patching, real-world incidents escalate. The WannaCry outbreak forced the UK’s NHS to cancel an estimated ~19,000 appointments, with total impact around £92 million.
• Higher breach costs: IBM’s 2025 report pegs the global average breach cost at $4.44M (with US costs higher), underscoring the financial risk of extended exposure on legacy platforms.
• ESU ≠ migration: Extended Security Updates keep some patches flowing, but don’t move apps, profiles, or settings—and per Microsoft guidance, Year 1 ESU lists around $61 per device via Volume Licensing, rising thereafter.

Fastest path forward: PCmover Enterprise

PCmover Enterprise is purpose-built for large-scale Windows 10 → 11 moves. Unlike file sync or backup tools, it migrates the full user environment—apps, profiles, settings, and files—so users log in to Windows 11 and get back to work with familiar desktops and applications.

Why enterprises choose PCmover Enterprise

• Full-stack migration: Applications + user profiles + settings + files (not just documents).
• At-scale automation: Policy-driven runs, scripting, and scheduling for phased rollouts.
• Flexible transfer methods: Live transfers (LAN or direct cable) or file-based export/import to fit any network constraint.
• Audit-ready visibility: Centralized logging and reporting for PMO, audit, and compliance.
• Proven ROI: Organizations routinely save $300+ per PC in IT time versus rebuild-and-reinstall approaches (from Laplink customer case studies).

FAQs

Is Windows 10 actually out of support now?

Yes—October 14, 2025 is the end-of-support date for Windows 10 (22H2, all editions). No more monthly security updates outside of ESU programs for organizations.

Can’t we just buy time with ESU?

ESU can reduce risk temporarily, but it’s a cost center and doesn’t move apps, profiles, or settings. You still carry operational risk, compatibility drift, and user downtime until you complete migration.

How big is the remaining Windows 10 footprint?

Market data shows Windows 10 near ~41% of Windows desktops going into the deadline, with analyst estimates of hundreds of millions of corporate PCs—many not yet upgraded—still requiring attention.
