If your computer still says “Windows 10” when it starts up, you’re not alone. It’s one of the questions we hear most at A. Computer Doctor right now: “Is my computer still safe to use? Do I have to buy a new one?”
The short answer: your Windows 10 PC still turns on and still works, but it no longer gets regular security fixes unless you take action. Here’s what happened, what your options are, and how to pick the right one for your home or business.
Microsoft ended support for Windows 10 on October 14, 2025. Since then, regular Windows 10 computers no longer get free feature updates, technical support, or security updates from Microsoft.
To give people more time, Microsoft offers the Windows 10 Extended Security Updates (ESU) program. In June 2026, Microsoft extended the consumer ESU program, so enrolled home PCs can keep getting critical security updates through October 12, 2027. If you’re already enrolled, your coverage continues automatically. ESU provides security updates only. It doesn’t add new features or include tech support.

A computer without security updates is like a house where the locks never get fixed. It may be fine for a while, but each new weakness that criminals discover stays open. For a home user, that can mean a higher risk of viruses, scams and stolen passwords. For a business, it can mean ransomware, downtime and lost customer data.
Some programs also stop supporting older versions of Windows over time, so an unsupported PC can slowly become harder to use.
Many computers bought in the last few years can upgrade to Windows 11 at no cost. Windows 11 has stricter hardware requirements than Windows 10, including a supported processor, TPM 2.0 and Secure Boot.
To check:
Before you upgrade, back up your files. Upgrades usually go smoothly, but a backup protects your photos, documents and business records if something goes wrong.
If your PC can’t run Windows 11, or you just aren’t ready to replace it, ESU keeps critical security updates coming through October 12, 2027. You sign in with a Microsoft account to enroll, and Microsoft shows you the enrollment options at that point. Your PC needs to be on Windows 10 version 22H2 to qualify.
Businesses have a separate ESU program for Windows 10 Pro and other commercial editions. If you run an office, we can help you figure out which one fits.
Think of ESU as a bridge, not a destination. It gives you time to plan and budget for new equipment instead of scrambling.
Sometimes a new PC makes the most sense, especially if your current one:
If you go this route, the key is moving your files, email, passwords, printers and programs over without losing anything. That’s where most of the headaches happen, and it’s a job we handle every day.
Be careful. Scammers love confusing moments like this. You may see pop-ups or get phone calls saying your computer is “expired” or “infected” and that you need to call a number or let someone connect remotely.
Microsoft will not call you out of the blue. Don’t give remote access or payment to anyone who contacts you first. If you’re unsure, close the browser, don’t call the number, and reach out to a local tech you trust.
If you run an office in Murrieta, Temecula or nearby, here’s a simple way to tackle it:
Our managed IT clients get this kind of planning, patching and backup as part of ongoing support, which keeps surprises to a minimum. Medical offices in particular should take this seriously, since outdated systems can put patient data at risk.

Can I still use Windows 10?
Yes. Your computer will keep working. But without ESU enrollment, it no longer gets security updates, which makes it riskier to use online.
How long does the consumer ESU program last?
According to Microsoft, consumer ESU coverage runs through October 12, 2027, and you can enroll any time until then.
How do I know if my PC can run Windows 11?
Check Windows Update or run Microsoft’s PC Health Check app. If you’d rather not guess, we can check it for you.
Will I lose my files if I upgrade?
An upgrade normally keeps your files and programs, but always back up first. If you replace your computer, we can move your data to the new one.
Do you help businesses as well as home users?
Yes. A. Computer Doctor supports both individuals and businesses of all sizes, including medical practices, across Murrieta, Temecula and surrounding cities.
A. Computer Doctor has been helping people and businesses in the Murrieta and Temecula area since 2006. The company was founded by Cesar Ramirez, a computer engineer (B.S., Cal Poly San Luis Obispo). Whether you need a Windows 11 upgrade, help with ESU, data transfer to a new PC, or a plan for your whole office, we’re happy to help.
