Short answer: Your PC won't stop working. Microsoft ended regular Windows 10 support on October 14, 2025, so it no longer gets security fixes unless you join Extended Security Updates (ESU), available until October 12, 2027. Back up your files first, then pick one of the five options below.

Which option fits you?

Pick your starting point
Your situation	Start with
Your PC passes the Windows 11 check	Option 2: Upgrade to Windows 11
It can't upgrade, but you want to keep it a while	Option 1: ESU, plus Option 3 if it feels slow
You mostly use the web, email and video	Option 4: ChromeOS Flex or Linux Mint
It's very old, or repairs cost a lot	Option 5: Replace it

Step zero: back up first

Whatever you choose, copy your important files before changing anything. A computer that still starts can still have a failing drive.

Photos, documents and anything saved on the desktop
Browser bookmarks and saved passwords (export them, or check they sync to your account)
Email archives if you use a desktop email program
Your BitLocker recovery key, if the drive is encrypted
Software license keys you can't download again

An external drive works well for this. External hard drives – search on Amazon – for keeping a full copy of your files.

Option 1: Join Windows 10 ESU

ESU keeps critical and important security updates coming until October 12, 2027. For home users there is a no-extra-cost option, a Microsoft Rewards option, and a one-time US$30 option. It adds no new features. Step-by-step instructions: how to enroll in Windows 10 ESU.

Best for: anyone who needs time to decide, or whose PC can't run Windows 11.

Option 2: Upgrade to Windows 11

If your PC meets Microsoft's requirements, upgrading is free and keeps you fully supported. The most common blocker is a processor that isn't on Microsoft's list. A disabled TPM is another, and that one is often easy to fix. Not sure? Check if your PC can run Windows 11 in about two minutes.

Best for: PCs that pass the check.

Option 3: Speed it up with an SSD

When an older PC feels slow, the cause is often a spinning hard drive rather than the processor. Replacing it with a solid-state drive (SSD) usually makes start-up and opening programs much faster. It doesn't change whether the PC can run Windows 11, so pair it with Option 1 or Option 4.

Worth it when: the PC still has a spinning hard drive and at least 4 GB of memory, and everything else works.
Not worth it when: the screen, hinges, keyboard or battery are also failing, or the total repair would cost close to a new PC.
Check first: whether your PC takes a 2.5-inch SATA drive or an M.2 drive. Your PC maker's manual or support page will say.

2.5-inch SATA SSDs – search on Amazon – for laptops and desktops with a standard drive bay.

Not comfortable opening the PC? Ask someone you trust, and back up first. Never let a stranger who contacts you first do it remotely.

Option 4: Switch to ChromeOS Flex or Linux Mint

Both are free and still receive security updates, so an older PC can stay safe online. Both can be tried from a USB drive before you install anything.

Quick comparison
	ChromeOS Flex	Linux Mint
Feels like	A Chromebook	A traditional desktop, similar to Windows
Account	Uses a Google account	No account required
Minimum hardware	64-bit Intel or AMD processor, 4 GB memory, 16 GB storage, can boot from USB	See the current release notes on the Linux Mint site
Good to know	Google only guarantees it on certified models; Intel or AMD parts from 2012 and earlier are unlikely to work	Works offline; many free programs available

What you give up: programs that only run on Windows, such as some tax, banking or work software. Installing either system replaces Windows and erases the drive, so back up first.

Best for: PCs used mainly for the web, email, video and documents.

Option 5: Replace the PC

Sometimes the most sensible fix is a new computer. Consider it when the PC is very old and slow even after an SSD, when several parts are failing at once, or when you depend on Windows-only software and the PC can't run Windows 11.

Before you give away or recycle the old one: back up, sign out of your accounts, and use Windows' "Reset this PC" with the option to remove everything and clean the drive. If you can't do that, remove the drive and keep it.

Watch out for these traps

"Upgrade" phone calls and pop-ups. Microsoft won't call you to sell ESU or Windows 11. ESU is enrolled inside Windows Settings, and you never need to give a stranger remote access.
Unofficial Windows 11 installs on unsupported PCs. They may work at first, but Microsoft says such PCs may not receive updates.
Panic repairs. If the PC is also clicking, freezing or failing to start, read the safe troubleshooting guide for older PCs before changing anything.

Frequently asked questions

How long can I keep using Windows 10?

Your PC keeps working, but Microsoft ended regular Windows 10 support on October 14, 2025. With consumer ESU it can keep receiving security updates until October 12, 2027.

What happens if I don't join ESU and don't upgrade?

Windows 10 still starts and runs, but new security problems are no longer fixed. The risk grows over time, especially for email, banking and shopping on that PC.

Is it safe to install Windows 11 on an unsupported PC?

Microsoft does not support Windows 11 on PCs that don't meet its requirements, and such PCs may not receive updates. For a PC you rely on, ESU or one of the other options here is the safer choice.

Will switching to ChromeOS Flex or Linux erase my files?

Installing either one to the internal drive replaces Windows and erases the drive. Back up first, and try it from a USB drive before installing.
