Microsoft’s blog recently gave a firm warning: unsupported systems aren’t just outdated, they’re unprotected. That message targets anyone still using Windows 10, and it’s serious. In Microsoft’s Digital Defense Report, over 90% of ransomware attacks hit unsupported PCs. That statistic alone should make every Windows 10 user think twice.
When an operating system stops receiving updates, it becomes an open door for hackers. Security patches dry up, and vulnerabilities grow. So while your computer might seem fine today, it could already be compromised without your knowledge.

Why are unsupported systems dangerous
Unsupported Windows 10 systems no longer get the updates that keep you safe. Without those patches, ransomware and malware have easy access to your files. Once inside, attackers can encrypt your personal data or steal credentials and banking details.
It’s not just about losing files. Identity theft and financial fraud often start with outdated systems. The older the software, the easier it is for cybercriminals to exploit weaknesses that will never be fixed.

The “just one more year” trap
Many people tell themselves they’ll upgrade later. Microsoft calls this “just one more year” thinking. The problem is that every delay increases your risk. Extended security updates only offer limited coverage, and they don’t stop new types of attacks.
Without Microsoft’s regular monitoring, new vulnerabilities stay hidden. You could be using your computer for months while attackers quietly collect your data. That’s a frightening thought, especially when most of it can be prevented by upgrading.

The hidden costs of waiting to upgrade to Windows 11
It’s easy to think upgrading costs too much. But what about the cost of losing your photos, business files, or financial information? Data recovery, fraud resolution, and downtime can cost far more than a new device.
Hackers know users delay updates, and they actively look for outdated systems. Even one unsupported device in a home or office network can create a weak spot that exposes everything else.

How to stay safe from unsupported Windows 10 security risks
You can protect yourself right now with a few smart steps. These actions reduce your exposure, tighten your online defenses, and prepare you for a smooth upgrade to Windows 11. The good news is that most of these changes only take a few minutes, but make a major difference in your security.
1) Upgrade your system to Windows 11
Start by checking if your PC can handle Windows 11. Most modern AMD and Intel processors already meet the system requirements. Upgrading keeps your computer protected with ongoing updates that patch vulnerabilities and improve overall performance. It’s one of the simplest ways to defend against ransomware and malware before they strike.
2) Watch out for phishing scams and install strong antivirus software
Be cautious with every link and attachment you receive. Cybercriminals love sending fake update notifications that look like official Microsoft messages. These phishing scams often contain malicious links that install malware in seconds. Before you click, hover over links to verify their source and only download updates directly from Microsoft’s official site. To add an extra layer of protection, install strong antivirus software that can detect and block malicious files before they infect your system.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.
TotalAV is easy to set up and offers real-time protection for paid users, keeping your devices safe around the clock. It includes tools to block phishing scams, remove ransomware and spyware, and clean up adware and junk files. The software also features a browser manager, system tune-up tools, and protects across Windows, Mac, Android, and iOS devices.

3) If you need help after your purchase, you can reach TotalAV directly through their official support page here.
3) Use a data removal service
Use a personal data removal service to take your information off people-search and data broker websites. These services help remove your name, address, phone number, and other personal details that scammers often use for phishing or social-engineering attacks. By limiting what’s publicly available about you, you make it much harder for cybercriminals to target you, especially if your older, unsupported Windows 10 system is ever exposed online.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy. These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.
Incogni, a service I trust 100% and use myself, helps automate the process by submitting removal requests to hundreds of data brokers and people-search sites on your behalf.
Incogni automatically contacts data brokers on your behalf and requests the removal of your personal information. It also continues monitoring those sites and submits new removal requests if your data reappears.
- Incogni currently removes personal data from 420+ data broker and people-search websites, and its Unlimited plan allows you to request removals from as many additional sites as you need.
- Incogni has also received third-party assurance from Deloitte, validating its marketing claims.
- The goal is simple: make it much harder for strangers, scammers, and cybercriminals to find your personal information online.
CyberGuy readers get 60% off Incogni’s annual plans using the links in this article.
The service also includes a 30-day money-back guarantee, so you can try it risk-free and see how much of your information is exposed online.

4) Secure your logins
Strong logins make a huge difference. Turn on two-factor authentication (2FA) for your most sensitive accounts, such as banking and email. Also, create strong passwords for your accounts and devices, and avoid using the same password for multiple online accounts. Consider using a password manager, which securely stores and generates complex passwords, reducing the risk of password reuse. This extra layer stops hackers, even if they manage to steal a password.

5) Back up your data regularly
Think of backups as your safety net. Save copies of important files to an external hard drive or a trusted cloud service. Schedule automatic backups so you don’t have to remember to do it yourself. If your PC ever gets locked by ransomware, a clean backup means you can restore everything without paying a cent.
6) Stay informed and proactive
Cyber threats evolve every day, and knowledge is your best defense. Keep an eye on official Microsoft announcements and alerts. Small changes, like applying updates quickly and revisiting your privacy settings, can keep you a step ahead of attackers.
Is there any way to stay protected on Windows 10 now that regular support has ended?
Yes, Microsoft officially ended regular support for Windows 10 on October 14, 2025. That means no more automatic updates, patches, or security fixes for most users. However, there is a temporary option called Extended Security Updates (ESU) for anyone not yet ready to upgrade.
The ESU program gives Windows 10 version 22H2 users an extra year of critical security updates, extending protection until October 13, 2026. These updates only cover major vulnerabilities, not new features or performance improvements. Microsoft says this program is meant as a bridge, not a long-term solution.
Even with ESU, Microsoft warns that older devices remain at higher risk. New attack methods can appear faster than security fixes arrive. The company continues to recommend upgrading to Windows 11 or buying a new PC that supports ongoing updates and modern hardware protection.

Kurt’s key takeaways
Unsupported systems might look harmless, but they create silent risks that grow over time. Every day you stay on Windows 10 after support ends, you depend on luck instead of protection. Upgrading isn’t just about staying current; it’s about keeping your data safe and your privacy intact.
Is holding on to Windows 10 worth risking everything stored on your computer? Let us know your thoughts in the comments below.

My home computer (HP desktop) does not support windows upgrade 11 because the processor isn’t currently supported according to Windows. I don’t want to purchase a new computer but I have purchased Total AV. Will that keep me safe?
Hi Deborah, you don’t need to replace your HP desktop yet. Even though it can’t upgrade to Windows 11, Microsoft will keep providing security updates for Windows 10 until October 14, 2025, and your purchase of TotalAV ($19 deal link here) gives you strong protection in the meantime. TotalAV blocks viruses, spyware, phishing scams, and dangerous websites through its real-time protection and WebShield features. Just make sure those are turned on, allow it to auto-update, and run a full system scan every week or so.
Beyond antivirus, keep Windows Update active, use a modern browser like Chrome or Edge, and regularly back up your important files using OneDrive, Google Drive, or an external hard drive. If you often connect to public Wi-Fi or want extra privacy, adding a trusted VPN such as ExpressVPN or Surfshark—both available through CyberGuy deals—will encrypt your traffic and help prevent snooping. With those steps, you can safely keep using your current computer well into next year without worry.
