It seems that the cybersecurity alarms are ringing loud and clear once again, and this time, Windows 10 is under the spotlight. Cybersecurity firm ESET is sounding the klaxon for Windows 10 users, urging them to upgrade to Windows 11—or switch altogether to an alternative operating system, like Linux—before October 2025. Why the urgency? Well, as the iconic OS approaches the end of its lifecycle, cybercriminals are licking their chops, waiting to exploit vulnerabilities. Brace yourselves, WindowsForum users, because we're diving into the nitty-gritty details of this "security fiasco" and what it means for you.
Microsoft made TPM a requirement to harden the OS against modern-day threats like ransomware. It’s also critical for enhanced security features, including Virtualization-Based Security (VBS) and Windows Defender System Guard.
But here’s the rub: many older devices are perfectly capable of running Windows 11 from a performance standpoint—but because they lack TPM 2.0, they are barred from upgrading. If that’s you, you’re likely stuck evaluating alternatives like purchasing new hardware or switching to operating systems like Linux.

The Looming Deadline: What Happens Post-Oct 2025?
Mark your calendars for October 14, 2025, because on this day, Microsoft will officially stop providing free security updates for Windows 10. That’s right—if you continue using the 10-year-old operating system without migrating or purchasing Microsoft's pricey Extended Security Updates (ESU), you’re essentially leaving your digital doors and windows wide open (pun intended) for hackers to walk through.What Does “End of Support” Mean?
When Microsoft declares end-of-support for an OS, it means:- No More Security Updates: Bugs, malware vulnerabilities, and zero-day exploits discovered post-October 2025 won’t be patched.
- Increased Cyber Risks: Unpatched OSes become prime targets for cyberattacks, ranging from ransomware to credential theft.
- No Technical Assistance: Let’s face it, Microsoft support phone lines are already busy; post-2025, you won’t even have the option to call.
ESET’s Stark Warning: A More Dangerous Repeat of the Windows 7 Migration
Remember the media frenzy back in 2020, when Windows 7 reached the end of its support and people scrambled to upgrade? You’d think history wouldn’t repeat itself, but according to ESET, the situation is “even more dangerous” this time around. Why? Let's break it down:- Usage Stats Favor Cybercriminals:
- A whopping 63% of Windows users worldwide are still on Windows 10, according to StatCounter as of December 2024.
- In comparison, by the time Windows 7's end-of-support loomed, over 70% of users had already transitioned to Windows 10. The migration process was smoother and quicker.
- Older Devices Are Trapped in Compatibility Limbo:
Many users can’t upgrade to Windows 11 due to its stringent TPM (Trusted Platform Module) requirement. Devices lacking TPM 2.0, or with unsupported CPUs, are effectively stuck unless users choose alternative operating systems like Linux. - Cybercriminals Know It’s Open Season:
Hackers are undoubtedly monitoring these stats. As ESET expert Thorsten Urbanski puts it, “They’re just waiting for the day when Windows 10 support ends.” October 14, 2025, could trigger an influx of ransomware attacks, malware exploits, and data breaches targeted at legacy systems.
The "TPM Wall" Blocking Upgrades
If the thought of upgrading to Windows 11 has you rubbing your temples, you’re not alone. One of the biggest barriers remains the TPM 2.0 requirement. But what exactly is TPM, and why does Microsoft insist on it?TPM Simplified:
The Trusted Platform Module, a physical or firmware-based security chip, essentially acts as your computer’s vault for sensitive data:- Protects cryptographic keys used by Windows Hello, BitLocker, and other security features.
- Ensures hardware integrity during the boot process (Secure Boot).
- Defends against credential theft.

The Alternatives: Should You Switch to Linux?
For those whose systems don’t meet Windows 11 requirements, the buzzword alternative swirling around is Linux. More and more tech enthusiasts, IT professionals, and even regular users are considering the open-source OS as a viable option. Here’s what you need to know:Why Linux Makes Sense:
- Cost: Linux distributions (e.g., Ubuntu, Fedora, Debian) are free and open-source.
- Security: Renowned for its robust security model, Linux systems are generally immune to Windows-specific malware types.
- Compatibility: Many everyday apps have Linux versions (e.g., LibreOffice, Firefox, ProtonVPN), and those that don’t (e.g., Adobe Photoshop) can sometimes run under compatibility layers like WINE.
- Community Support: The Linux community is famously helpful, with forums and tutorials galore.
Challenges to Consider:
- Learning Curve: For first-time Linux users, figuring out the terminal and package managers can feel daunting.
- Software Gaps: Some niche programs (e.g., advanced photo or video editors) might lack full-feature parity with Windows versions.
- Gaming Troubles: While gaming on Linux has made leaps with tools like Proton and Steam Play, hardcore gamers may still experience hiccups.
Extended Security Updates (ESU): To Buy or Not to Buy?
For businesses or die-hard Windows 10 users unwilling to jump ship, Microsoft offers a safety net in the form of Extended Security Updates (ESU). However, brace yourself—this “insurance policy” doesn’t come cheap:Pricing Breakdown for Businesses:
- $61 for Year 1
- $122 for Year 2
- $244 for Year 3
Consumer Pricing:
A one-year ESU plan costs $30 per device. If you have multiple household devices, the total can quickly skyrocket. For cost-conscious users juggling outdated hardware, the question becomes: Is it worth sinking more money into a sinking ship?Gaming Communities Are Leading the Way
Interestingly, gamers are already leaving Windows 10 in the dust. According to Steam’s Hardware Survey (December 2024):- 54.96% of gamers are on Windows 11.
- Only 42.39% remain on Windows 10.
Final Thoughts: What Should You Do Now?
Windows 10 enthusiasts, the reality is clear. October 14, 2025, might sound a long way off, but when it comes to cybersecurity, time waits for no one. Let’s break it down simply:- If your device is compatible with Windows 11: Upgrade ASAP. Do not pass “Go.” Do not collect malware.
- If your device is stuck without TPM 2.0: Seriously consider Linux as an alternative. Ubuntu, Fedora, or Mint are great starting points.
- If neither option appeals to you: Prepare to invest in one-time ESU fees, but understand this is merely kicking the can down the road.
