If you have landed here looking for a way to put Windows 10 on an older laptop, the honest answer is that you should not. Microsoft ended support for Windows 10 on October 14, 2025, so installing it today means starting out on an operating system that receives no security updates unless you separately enroll it in a paid or account-linked program.
What most people actually need in 2026 is the next step up: find out whether the laptop in front of you is allowed to run Windows 11, upgrade it if it is, and pick a sensible fallback if it is not. This guide covers the eligibility check, the two supported upgrade routes, the clean-install path, and what to do with hardware Microsoft has locked out.
Do not install Windows 10 on a laptop in 2026. A fresh Windows 10 install is unpatched from day one. If the machine cannot run Windows 11, keeping an existing Windows 10 install enrolled in Extended Security Updates is defensible; deliberately putting Windows 10 onto a machine now is not.

Why Upgrading to Windows 10 Is the Wrong Goal Now
The original reason people searched for this was Windows 7. Microsoft ended Windows 7 mainstream support on January 13, 2015 and extended support on January 14, 2020, which pushed a large group of holdouts toward Windows 10. That migration is over. Windows 10 has now reached the same endpoint Windows 7 did.
Nothing breaks the day support ends. What stops is security patching, and that gap compounds every month. We cover the wider decision in detail in our breakdown of what to do now that Windows 10 is dead, including the case for and against paying to stay put.
Windows 11 is the current release. Version 25H2 is the shipping feature update through most of 2026, with 26H2 having reached the Release Preview Channel in August 2026. If your laptop qualifies, this is where it should end up.
Windows 11 Minimum Requirements for an Older Laptop
These are the floor, not a recommendation. Microsoft’s published Windows 11 specifications list:
- 1 GHz or faster, two or more cores, on a compatible 64-bit processor or SoC
- 4 GB RAM
- 64 GB or larger storage device
- UEFI firmware with Secure Boot capability
- Trusted Platform Module (TPM) version 2.0
- DirectX 12 or later graphics with a WDDM 2.0 driver
- 720p display larger than 9 inches diagonally, 8 bits per color channel
The two that actually disqualify most older laptops are TPM 2.0 and the CPU compatibility list. Meeting the megahertz and core count is not enough — Microsoft maintains a named list of supported processors, and a machine can have a fast chip that simply is not on it.
Four gigabytes of RAM is a bare minimum in the licensing sense rather than a usable target. If the laptop is upgradable and sitting at 4 GB, adding memory is the cheapest thing you can do for it, though soldered memory has become the norm on thinner machines.
How to Check If Your Laptop Can Run Windows 11
Check 1: Windows Update
On a Windows 10 machine, open Settings > Update & Security > Windows Update. If the laptop is eligible, the upgrade to Windows 11 is offered there directly. If it is not, the same page usually says so and names the requirement that failed.
On a machine already running Windows 11, the equivalent page is Settings > Windows Update — the “Update & Security” grouping from Windows 10 no longer exists.
Check 2: PC Health Check
PC Health Check is Microsoft’s own eligibility app and remains the tool it points to on the Windows 11 specifications page. Install it, click Check now under the Windows 11 introduction, and it reports pass or fail with the specific blocking requirement named.
A “fail” on Secure Boot or TPM is worth a second look before you accept it. Both are firmware settings on many 2016–2019 laptops, shipped switched off, and switching them on can move a machine from ineligible to eligible without any hardware change.
Check 3: TPM and Secure Boot by Hand
- Press Windows + R, type tpm.msc and press Enter. The TPM Management console reports whether a TPM is present and, under Specification Version, whether it is 2.0 or the older 1.2.
- Press Windows + R, type msinfo32 and press Enter. In System Summary, check BIOS Mode reads UEFI (not Legacy) and Secure Boot State reads On.
- If BIOS Mode says Legacy or Secure Boot is off, the fix lives in firmware rather than Windows. Look for TPM, PTT, fTPM or “Security Device Support”, plus Secure Boot, in the firmware setup screens.
Getting into those screens differs by brand, and the key has to be pressed in the first second or two after power-on. If you are not sure which one your machine uses, the brand-by-brand BIOS entry keys are collected here.
- Acer and Asus: F2 or Del
- Dell: F2 or F12
- HP: Esc or F10
- Lenovo: F1, F2, or Fn + F2
- Lenovo ThinkPad: Enter, then F1
- MSI: Del
- Microsoft Surface: press and hold volume-up while powering on
- Samsung and Toshiba: F2
- Sony: F1, F2, or F3
Switching Secure Boot on can stop the laptop booting. A Windows install made in Legacy/CSM mode will not start under UEFI Secure Boot. Convert the disk to GPT with Microsoft’s MBR2GPT tool first, or expect to reinstall. Back up before touching either setting.
Upgrading a Laptop From Windows 10 to Windows 11
Back up first. Every route below is recoverable in theory and inconvenient in practice, and an in-place upgrade that fails halfway is a genuinely bad afternoon. Copy anything you care about to cloud storage or an external drive before you start, and keep the laptop on mains power throughout.
Route 1: Windows Update, In Place
- Open Settings > Update & Security > Windows Update.
- If the Windows 11 upgrade is offered, select Download and install.
- Accept the license terms and let it download in the background. You can keep using the laptop.
- Restart when prompted. The machine reboots several times; do not interrupt it.
- Work through the setup prompts for region, keyboard and privacy settings.
This keeps your files, apps and most settings. No product key is needed — an activated Windows 10 license carries over.
Route 2: Installation Assistant or Media Creation Tool
If the laptop passes the eligibility check but Windows Update has not offered the upgrade yet, Microsoft’s Windows 11 download page hosts both the Installation Assistant and the Media Creation Tool. The Assistant upgrades the machine you run it on; the Media Creation Tool builds a bootable USB drive.
- Download and run the Installation Assistant, then accept the license terms.
- It re-runs the compatibility check and refuses to continue if the machine fails.
- Let it download and install. Files and apps are kept by default.
- Restart when prompted and finish the setup screens.
Route 3: Clean Install From a USB Drive
A clean install wipes the drive and is the right choice for a laptop you are passing on, or one whose Windows install has degraded past the point of repair. Optical media is not part of this any more — build a USB stick with the Media Creation Tool instead.
- Back up everything. This step is destructive.
- Create the installation USB with the Media Creation Tool on any working PC.
- Boot the target laptop from USB, using the one-time boot menu or the boot order in firmware.
- Choose language, time and keyboard, then Install now.
- Select I don’t have a product key if the laptop was previously activated — the digital license reapplies after install.
- Choose Custom: Install Windows only (advanced), delete the existing partitions on the target disk, and select the resulting unallocated space.
- Work through region, keyboard, network and account setup to reach the desktop.
Setup for Windows 11 Home and Pro expects an internet connection and a Microsoft account, and Microsoft has closed several of the workarounds that used to skip that screen. Plan on signing in during setup and converting to a local account afterwards if you want one.
What to Do If Your Laptop Cannot Run Windows 11
Stay on Windows 10 With Extended Security Updates
Microsoft’s consumer Extended Security Updates program keeps security patches flowing to Windows 10. Enrollment is free if you sync your PC settings to a Microsoft account, free for 1,000 Microsoft Rewards points, or a one-time $30 purchase, and a single license covers up to 10 devices.
The ESU deadline moved. Consumer ESU was originally set to end in October 2026. Microsoft quietly pushed the end date out to October 12, 2027 via a documentation update rather than an announcement. Coverage is security patches only — no feature updates and no general support.
Move to Linux
Hardware Windows 11 rejects for TPM reasons is often perfectly capable otherwise. Ubuntu, Linux Mint and Zorin OS all install on machines of this vintage and stay patched indefinitely. The cost is a learning curve and manually moving your files across, and some Windows-only software will not follow you.
Force Windows 11 Onto Unsupported Hardware
Registry edits and modified install media can get Windows 11 running on machines that fail the check. Microsoft’s position is that this is not recommended, and that upgrading without passing the eligibility check “could leave a system in an unsupported state”. An unsupported install is not guaranteed to keep receiving updates.
That trade may be acceptable on a spare machine. It is a poor choice for the laptop you rely on, because the failure mode is losing patches on the exact device you needed patched.
Replace or Retire the Laptop
For a machine old enough to fail the CPU list, replacement is often the cheaper path once you price the alternatives. If the old one is going out of service, recycling it properly matters more than usual — these are exactly the machines that end up in a drawer with an unwiped drive in them.
Problems That Show Up After the Upgrade
Older software is the usual casualty. Anything relying on 32-bit installers, unsigned drivers, or long-abandoned hardware support may not survive the jump, and the fix is generally a current version rather than a workaround.
Peripherals are the second category — scanners, printers and docks whose vendors stopped writing drivers years ago. Check the manufacturer’s support page for a Windows 11 driver before the upgrade rather than after.
If the laptop feels slower on Windows 11 than it did on Windows 10, the storage is the first place to look. A mechanical hard drive is the single biggest drag on a machine of this age, and swapping it for an SSD changes the experience more than any software tweak will.
Can I still install Windows 10 on a laptop in 2026?
Technically yes, if you have installation media and a valid key. It is a bad idea. The install receives no security updates from October 14, 2025 onward unless you separately enroll it in Extended Security Updates, so you would be creating a machine that needs patching on day one and cannot get it.
Is upgrading from Windows 10 to Windows 11 free?
Yes, on eligible hardware. An activated Windows 10 license upgrades to Windows 11 at no charge through Windows Update or the Installation Assistant, and no new product key is required.
Why does my laptop fail the Windows 11 check when the specs look fine?
Almost always TPM 2.0 or the processor list. Microsoft requires a TPM 2.0 module and a CPU that appears on its named compatibility list, so a machine can comfortably clear the clock speed, RAM and storage figures and still be blocked. PC Health Check names the specific requirement that failed.
Do I need to back up before upgrading?
Yes. An in-place upgrade normally keeps your files, but “normally” is doing real work in that sentence. Copy anything irreplaceable to cloud storage or an external drive first, and keep the laptop plugged in for the whole process — a power loss mid-upgrade is one of the few ways to genuinely break the install.
Will my old programs still work after moving to Windows 11?
Most will. The ones that break tend to be old utilities with unsigned drivers, software tied to discontinued hardware, and anything that has not been updated in a decade. Look for a current version first; if there is none, find a replacement rather than disabling driver signature enforcement to force it.
What are the minimum requirements for Windows 11?
A 1 GHz or faster 64-bit processor with two or more cores from Microsoft’s supported list, 4 GB of RAM, 64 GB of storage, UEFI firmware with Secure Boot capability, TPM 2.0, DirectX 12 graphics with a WDDM 2.0 driver, and a 720p display over 9 inches. TPM and the CPU list are the two that block most older laptops.
Can I go back to Windows 10 if I do not like Windows 11?
There is a rollback option in Settings for a limited window after an in-place upgrade, found under Settings > System > Recovery. After that window closes the option disappears and going back means a clean install — onto an operating system that is now out of support, which is rarely the outcome you want.
Final Thoughts on Updating an Old Laptop in 2026
Run the eligibility check before anything else, because the answer decides everything that follows. Eligible machines should go to Windows 11 through Windows Update and keep their files; ineligible ones need a deliberate choice between ESU as a dated bridge, Linux, or replacement.
The one path that no longer makes sense is the one this page used to describe.
