Millions of Windows 10 users are heading toward a security cliff that could leave their computers vulnerable to cyberattacks, malware, and data breaches. Microsoft’s official support for Windows 10 ends on October 14, 2025, and many users remain unaware of what this deadline means for their digital safety.
What Happens When Support Ends?
When Microsoft ends support for Windows 10, the company will stop releasing security patches and bug fixes for the operating system. This means that when hackers discover new vulnerabilities in Windows 10 – and they will – there won’t be any official fixes coming from Microsoft.
Think of it like living in a house where the security company stops monitoring your alarm system and won’t respond to break-ins. The house still functions, but you’re on your own when threats emerge.
The implications extend beyond individual users:
- Personal computers become targets for malware and ransomware attacks
- Business networks face increased risk of data breaches
- Connected devices may become entry points for broader security compromises
- Software compatibility issues will emerge as other programs drop Windows 10 support
The Scale of the Problem
The numbers reveal the magnitude of this security crisis. As of late 2024, Windows 10 still runs on approximately 67% of all Windows computers worldwide. This represents hundreds of millions of devices that will lose security support simultaneously.
| Windows Version | Market Share | Support Status |
|---|---|---|
| Windows 11 | 26% | Active support until 2031 |
| Windows 10 | 67% | Ends October 2025 |
| Other versions | 7% | Already unsupported |
This creates an unprecedented situation where the majority of Windows users will need to make critical security decisions within months of each other.
Why Many Users Can’t Simply Upgrade
The obvious solution might seem like upgrading to Windows 11, but millions of computers cannot run Microsoft’s newer operating system due to strict hardware requirements. Windows 11 demands:
Hardware Requirements That Block Upgrades
- TPM 2.0 chip – A security processor absent from many computers built before 2017
- 8th generation Intel processors or newer – Excluding many perfectly functional computers
- UEFI firmware with Secure Boot – Not available on older systems
- 8GB of RAM minimum – More than many budget computers include
Many users discovered their computers, some only a few years old, don’t meet these requirements. This has created a situation where functional hardware becomes a security liability not because it’s broken, but because it can’t run supported software.
Extended Security Updates: A Costly Band-Aid
Microsoft has announced Extended Security Updates (ESU) for Windows 10, but this solution comes with significant limitations. Individual users can purchase continued security updates for $30 for the first year, with prices increasing annually.
ESU Pricing Structure
| Year | Consumer Price | Business Price (per device) |
|---|---|---|
| Year 1 (2025-2026) | $30 | $61 |
| Year 2 (2026-2027) | $60 | $122 |
| Year 3 (2027-2028) | $120 | $244 |
While ESU provides a temporary solution, it’s designed to be increasingly expensive to encourage migration to newer systems. For many users, these costs may exceed the value of their current computer.
Your Options Before the Deadline
Windows 10 users have several paths forward, each with distinct advantages and challenges:
Option 1: Upgrade to Windows 11
Best for: Users with compatible hardware who want to stay in the Microsoft ecosystem
Steps to take:
- Check compatibility using Microsoft’s PC Health Check tool
