Windows 10 End of Support: What to Do Now That the Date Has Passed

Windows 10 support ended on 14 October 2025. If you are reading this on a Windows 10 PC today, Microsoft is no longer sending it security updates, and every vulnerability found since that date remains open on your machine. This guide covers the three things you can actually do about it now — enrol in Microsoft's paid-or-free extension, upgrade to Windows 11, or replace the PC — and how to tell which one applies to you.

Esmond Service Centre has assisted countless customers in Singapore with system upgrades and tech issues, so you can trust the advice here. We draw on insights from Esmond’s certified technicians – in fact, Esmond Service Centre has been recognized by major media like TheSmartLocal and Mothership.sg as one of Singapore’s top tech repair specialists. Our team regularly hears concerns about Windows upgrades, especially as end-of-support nears. With their expertise and 16+ years of IT repair experience, this guide delivers practical steps to help every reader confidently handle the Windows 10 end of support transition.

Mark the Windows 10 End-of-Support Date and Understand the Risks

Windows 10 reached end of support on 14 October 2025. Microsoft's own lifecycle notice is blunt about what that means: these editions "will no longer receive security updates after October 14, 2025", and anyone who contacts Microsoft Support is directed to upgrade or replace the device. Microsoft's Singapore site now carries the same line in the past tense at the top of every Windows page.

Why this matters more than it sounds. An unsupported PC does not break on the day support ends — it degrades quietly. Each month brings new vulnerabilities that get patched on Windows 11 and not on yours, so the gap widens rather than holding steady. You may also find banking apps, VPNs and business software start refusing to run, and some cyber-insurance and corporate IT policies will not cover an unsupported operating system at all.

And this is not a small group in Singapore. [MEASURED — StatCounter, Desktop Windows Version Market Share in Singapore, July 2026] Windows 11 holds 73.33% and Windows 10 still holds 25.53% — about one in four Singapore Windows desktops is running an operating system that stopped receiving security updates ten months ago. If that is your PC, the next section is the one that matters.

Still on Windows 10 Today? Your Three Options

Because the deadline has passed, "plan ahead" is no longer advice anyone can use. Here is what is actually available, taken from Microsoft's own pages on 29 August 2026.

Option 1 — Enrol in Extended Security Updates (ESU), and it can cost you nothing. Microsoft runs a consumer ESU programme for Windows 10 that keeps critical and important security updates coming. Its own page states you can "enroll in ESU any time until the program ends on October 12, 2027". There are three ways in:

• Free — if you are syncing your PC settings with Windows Backup.
• 1,000 Microsoft Rewards points — redeemed instead of paying.
• A one-time purchase of US$30 (or local currency equivalent) plus tax.

⚠️ You will see other dates quoted, and they are out of date. Several guides still say the programme runs "one more year, to October 2026" — that was true of an earlier version of it. Microsoft's own Windows 10 ESU page and its own support article both now say 12 October 2027. Check Microsoft's page, not a summary of it.

What ESU does and does not give you. It delivers critical and important security updates only — no feature updates, no other bug fixes, and no technical support. Your PC must be on Windows 10 version 22H2 with the latest updates installed, and you must sign in with a Microsoft account that is an administrator and not a child account. One enrolment covers up to 10 devices. To start: Settings > Update & Security > Windows Update, then Enroll now. Two things ESU cannot do, because people reasonably assume otherwise. It will not make an ineligible PC able to run Windows 11 — the hardware requirements are unchanged — and it cannot fix a fault the machine already has. ESU only stops new security holes from going unpatched; a slow, crashing or failing PC stays slow, crashing or failing.

Option 2 — Upgrade to Windows 11, which is still free for eligible PCs. Microsoft's Singapore specification page lists the minimum requirements as a 1 GHz or faster 64-bit processor with 2 or more cores, 4 GB of RAM, 64 GB of storage, UEFI firmware that is Secure Boot capable, TPM 2.0, a DirectX 12 compatible graphics card and a 720p display larger than 9 inches. Your PC also has to be running Windows 10 version 2004 or later to take the upgrade. The rest of this guide walks that through.

Option 3 — Replace the PC. If the hardware genuinely cannot meet those requirements, this is the honest answer, and ESU is the way to stay protected while you decide rather than a reason to put it off indefinitely. ⛔ Note that ESU ends on 12 October 2027 for everyone regardless of when you enrol — enrolling late does not buy you extra months at the far end.

Is My PC Compatible With Windows 11 Before Windows 10 End of Support?

Now that Windows 10 support has ended, upgrading is the cleanest path forward, but not every older PC can run Windows 11. Microsoft introduced strict hardware requirements for Windows 11, so you need to verify whether your current machine is eligible. The easiest way is to use Microsoft’s PC Health Check app, which scans your system and reports if it meets Windows 11’s minimum specifications. These include having a modern 64-bit processor, TPM 2.0 security module, UEFI Secure Boot capability, at least 4 GB RAM, and at least 64 GB storage free. Most PCs built in the last 4–5 years will pass, but many older ones may fail due to missing TPM or an unsupported CPU.

How to check compatibility (step-by-step):

1. Download and run PC Health Check: Visit Microsoft’s Windows 11 website and download the official PC Health Check tool. Launch the app and click “Check Now”.
2. Review the result: The tool will quickly assess your hardware and either show a success message (your PC is compatible) or a failure message. If compatible, you’re clear to upgrade. If not, note the reason it gives (e.g. “Processor not supported” or “TPM not detected”).
3. (Optional) Adjust settings if possible: Sometimes a PC fails simply because a feature like TPM or Secure Boot is disabled in BIOS. If your report indicates that, you can reboot into your BIOS settings to enable TPM 2.0 and Secure Boot, then run the check again. ⚠️ Change one setting at a time and write down what it was before. On a PC that was installed in legacy or CSM mode, switching Secure Boot on can stop Windows booting at all — if that happens, go back into BIOS and switch it off again, and bring the machine in rather than changing anything else. This might make an otherwise modern PC pass the requirements.
4. Decide on upgrade or replacement: If your PC still doesn’t meet the Windows 11 specs (for example, very old CPU or motherboard with no TPM), you have to decide if you’ll replace the device or consider other options. Microsoft’s official guidance for unsupported devices is to purchase a new Windows 11–ready PC. Continuing to use an incompatible machine past Windows 10 end of support isn’t safe, so replacing the device is the wise choice if it cannot run Windows 11.

Why this works: Using the PC Health Check ensures you don’t attempt an upgrade on incompatible hardware. It’s a quick diagnostic that saves time and frustration. By identifying any roadblocks now, you can either resolve them (e.g. enable TPM) or plan for a new PC. Upgrading to Windows 11 is only smooth when your system meets the requirements – this step guarantees you know where you stand.

Back Up Your Files and Prepare for the Upgrade

Before you attempt any upgrade, back up your important data. While upgrading from Windows 10 to 11 generally preserves your files and apps (Microsoft designed the process to carry everything over automatically), it’s better to be safe than sorry. Unexpected glitches or user errors could cause data loss if something goes wrong. Preparing a backup and doing some housekeeping will make your Windows 11 transition worry-free.

Steps to prepare:

• Backup important data: Copy your documents, photos, and other vital files to an external hard drive or a cloud service like OneDrive. Windows offers built-in tools as well – for example, you can enable OneDrive PC folder backup to sync your Desktop, Documents, and Pictures to the cloud. Having a recent backup means that even if the upgrade encounters issues, your data remains safe.
• Update Windows 10 and drivers: Ensure your current Windows 10 installation is fully updated (open Settings > Update & Security and install any pending updates). Also, update critical device drivers (graphics, network, etc.) if newer versions are available. A fully patched Windows 10 is less likely to experience upgrade errors.
• Free up disk space: Windows 11 needs adequate disk space for the installation. Microsoft requires at least 64 GB free, though more is better. Delete unnecessary files or use the built-in Disk Cleanup utility to clear temporary files. If your drive is almost full, the upgrade might fail or slow down.
• Temporarily disable antivirus: In some cases, third-party antivirus programs can interfere with OS upgrades. Consider disabling or uninstalling any non-Microsoft security software just during the upgrade process (remember to re-enable it afterward, or rely on Windows Security which is built-in). ⚠️ And because your PC is not receiving security updates right now, do not browse or download while its antivirus is off — disconnect from the internet if you can, and turn the protection back on the moment the upgrade finishes..
• Prepare login info: Make sure you know your Microsoft account credentials, since Windows 11 Home requires signing in with a Microsoft account during setup. If you currently use a local account on Windows 10, be ready to create or use a Microsoft account for the upgrade.

Why this works: Backing up and cleaning up beforehand ensures that nothing important is lost and that the upgrade has the best environment to succeed. A backup is your safety net (even though upgrades usually keep files intact). Updating Windows 10 first can fix known issues and improve compatibility with the new OS. Free disk space gives the installer room to work, preventing aborted installations due to low space. These preparations collectively lead to a smoother, faster upgrade with minimal downtime and hassle. And with Windows 10 end of support fast approaching, these preparations set you up for a smooth upgrade when it counts.

Perform the Windows 11 Upgrade

With compatibility confirmed and backups in place, you’re ready to actually install Windows 11. There are two primary ways to upgrade from Windows 10:

• Windows Update (recommended): If your PC is eligible, the upgrade to Windows 11 is delivered via Windows Update like a regular update. This is the simplest method.
• Windows 11 Installation Assistant: If Windows Update isn’t showing the upgrade (or if you prefer manual control), you can download Microsoft’s Installation Assistant tool to initiate the upgrade.

For compatible PCs, simply go to Settings > Update & Security and click “Check for updates” – a prompt to “Download and install Windows 11” will appear when available. Upgrading through Windows Update preserves your files and applications seamlessly.

Upgrading via Windows Update: Microsoft has been rolling out the Windows 11 upgrade to Windows 10 users for free. Go to Settings > Update & Security > Windows Update and click “Check for updates.” If your device meets all requirements, you should see an option to upgrade to Windows 11 (it might say “Upgrade to Windows 11 is ready – and it’s free”). When you see this, click the Download and Install button and follow the prompts. The system will download ~4–5 GB of data, then prompt for a restart to begin installation. Leave your PC on and plugged in during the process, as it may take 20–30 minutes or more and involve several reboots. When finished, you’ll be taken to the Windows 11 desktop. (Tip: Upgrading early—well before the Windows 10 end of support cutoff—ensures your PC stays supported and secure.)

Upgrading via Installation Assistant: If Windows Update doesn’t offer the upgrade (perhaps due to a phased rollout), you can use Microsoft’s official Installation Assistant. Download it from Microsoft’s website and run the tool – it performs the same in-place upgrade process. The Assistant will check your PC’s compatibility again, then download Windows 11 and install it. Follow the on-screen steps (agree to license terms, etc.) and let it run. This method also keeps your files and apps intact. It’s a good alternative if you want to upgrade immediately without waiting for Windows Update to push it to you.

Why this works: Using Microsoft’s provided upgrade paths ensures a supported, legitimate installation of Windows 11. The in-place upgrade process is designed to transition you to the new OS with minimal effort on your part – no need to manually reinstall anything. By upgrading now (well before the Windows 10 end of support date), you guarantee that your PC continues to receive updates and remains secure. Both Windows Update and the Installation Assistant are straightforward; they automate the complex parts so you can simply follow the prompts. The result is that you’ll be on Windows 11 with all your data preserved, and back on an operating system that still receives security updates.

Post-Upgrade Tips and Getting Professional Help if Needed

Congratulations – if everything went well, your PC should now be running Windows 11 and back on a supported operating system. After the upgrade, there are a few final things to do to ensure you’re getting the best experience:

• Familiarize yourself with Windows 11: Take a tour of the new interface. The Start menu and taskbar are centered by default (you can move them to the left if you prefer). Explore the new Settings app, Microsoft Store, and features like Snap Layouts for window organization. Windows 11 still works similarly to Windows 10 in most ways, so you’ll get comfortable quickly.
• Check for updates on Windows 11: After installation, go to Settings > Windows Update again and download any post-upgrade patches or driver updates. Microsoft frequently releases fixes, and hardware makers might have new drivers optimized for Windows 11 – installing these will polish any rough edges from the upgrade.
• Verify your apps and devices: Ensure all your important applications are running fine on Windows 11. Nearly all programs that worked on Windows 10 will work on Windows 11, but if you encounter an issue, check the software publisher’s site for a Windows 11–compatible version. Also test peripherals (printer, webcam, etc.) – if something isn’t recognized, reinstalling the device driver can solve it.
• Restore disabled software: If you removed or turned off any antivirus or special tools before upgrading, now is the time to reinstall or re-enable them. Windows 11’s built-in Windows Security likely took over if no other antivirus was present, so you are protected either way. Reapply any settings as needed.

When to seek help: If at any point you feel overwhelmed – say the PC Health Check showed incompatibility and you’re unsure what new PC to buy, or you ran into errors during the upgrade – it’s wise to consult professionals. Upgrading hardware or dealing with technical hiccups can be complex. Esmond Service Centre offers support for such cases, from advising on Windows 11–ready hardware to performing data migration. Remember, the goal is to stay protected after Windows 10 end of support, and there’s no shame in getting expert assistance to make that happen. It’s far better to ask for help than to risk running an outdated, unsafe system. With Windows 10 end of support so close, it’s far better to seek help than risk staying on an outdated, unsafe OS.

Why this works: Following post-upgrade best practices ensures you truly reap the benefits of Windows 11. Checking for updates and drivers fine-tunes your system’s stability and performance. Verifying apps and devices catches any compatibility issues early so they can be resolved, keeping your workflow uninterrupted. And knowing when to get help means you won’t stay stuck if a problem arises. Professionals like the team at Esmond Service Centre can quickly resolve upgrade snags or even handle the entire process for you if needed. In the end, you’ll be fully moved on from Windows 10, equipped with a secure system and expert support if anything goes wrong.

When to Stop and Bring the PC In

The honest cost of getting this wrong is not the upgrade fee. An in-place upgrade that fails mid-write can leave a machine that will not boot, and the risk to your data is highest on exactly the drives that were never backed up. Running on without ESU carries its own cost, which compounds: every month unpatched adds vulnerabilities that will never be fixed on that installation.

If any of that describes your situation, bring the machine in. Esmond Service Centre works on Windows PCs at two Singapore branches, Alexandra and Sin Ming, with 16 years of IT repair behind it and a free diagnosis before any work starts — we will tell you whether your PC can take Windows 11, whether it can enrol in ESU, and what each route would cost, and you decide after that. ⛔ We do not quote a flat upgrade price here on purpose: the honest number depends on what the diagnosis finds. See Windows OS repair in Singapore.

Upgrade Now for a Safer, Smoother PC Experience

In short: the deadline is behind us, not ahead. If you are still on Windows 10, enrol in ESU today so the machine stops accumulating unpatched vulnerabilities, then check whether it can take Windows 11 and upgrade it if it can. If it cannot, use the ESU window to plan a replacement properly instead of buying under pressure.

The single most useful thing you can do in the next ten minutes is open Settings > Update & Security > Windows Update and see what your PC is offered — an ESU enrolment link, a Windows 11 upgrade, or neither. That one screen tells you which of the three options above is yours.
