Your laptop can run Windows 11 if it has a supported 64-bit processor (generally Intel 8th generation or newer, or AMD Zen+ and newer), TPM 2.0, UEFI firmware with Secure Boot capability, at least 4GB of RAM and 64GB of storage. Microsoft's PC Health Check app, or Settings, Windows Update, will tell you in a minute whether yours qualifies.
Windows 10 lost regular Microsoft support on 14 October 2025, so this question has stopped being optional for many owners. The good news is that RAM, storage, TPM and Secure Boot can often be fixed cheaply. The bad news is that the processor can't, so check that first and spend nothing until you know.
How do you check compatibility in two minutes?
Start with the quick route, then dig into the details only if the answer is no.
- Open Settings, Windows Update. If your laptop qualifies, Windows shows an upgrade offer. If it doesn't, it says the PC doesn't meet the requirements.
- Run Microsoft's PC Health Check app. It names the exact requirement that fails.
- Press Windows+R, type tpm.msc and check the status for Specification Version 2.0.
- Press Windows+R, type msinfo32 and look at BIOS Mode, which should read UEFI, and at Secure Boot State.
- Open Settings, System, About and note the processor name to compare against Microsoft's list of supported processors.
What are the actual requirements, and which can you fix?
The table lists the main requirements and whether you can change them. Where the answer is "often", the fix is usually a setting in the BIOS.
| Requirement | Minimum | Fixable? |
|---|---|---|
| Processor | 64-bit, 1 GHz or faster, two or more cores, on Microsoft's supported list | No, the processor is fixed in nearly all laptops |
| Memory | 4GB (8GB is more comfortable) | Yes, with a RAM upgrade if there's a slot |
| Storage | 64GB or more | Yes, with a larger SSD |
| Firmware | UEFI with Secure Boot capability | Often, by changing BIOS settings and converting the disk |
| TPM | Version 2.0 | Often, by turning on Intel PTT or AMD fTPM in the BIOS |
| Graphics | DirectX 12 and WDDM 2.0 driver | Rarely a problem |
Windows 11 version 24H2 and later also needs a processor that supports certain instructions (SSE4.2 and POPCNT), which very old chips lack. Our Windows 11 24H2 compatibility checklist goes into the finer points.
Which laptops usually pass, and which usually fail?
Processor generation is the dividing line. Intel 8th-generation chips and newer generally pass, and so do AMD chips based on the Zen+ design or newer. An Intel Core i5-8250U passes, while a Core i5-7200U from the generation before doesn't. Laptops sold in 2018 and 2019 could carry either, so don't judge by purchase year. Laptops from 2017 or earlier almost always fail on the processor.
Always confirm your exact model against Microsoft's list, because there are small exceptions and the naming can be confusing. If the processor is on the list and the machine only fails on memory, storage, TPM or Secure Boot, you can fix it.
What can you fix, and what is a dead end?
Fixable problems
- Not enough memory. Our list shows 8GB at ₹1,499 to ₹2,499 and 16GB at ₹2,499 to ₹3,999, indicative. See laptop RAM upgrade.
- Too little storage. A 256GB SSD is listed at ₹3,499 – ₹4,999 and a 512GB at ₹2,499 to ₹3,999, indicative. See laptop SSD upgrade.
- TPM switched off. Enter the BIOS and enable the firmware TPM, which Intel calls PTT and AMD calls fTPM.
- Secure Boot or legacy mode. Switch the firmware to UEFI and enable Secure Boot. If Windows was installed in legacy mode on an older MBR disk, Microsoft's built-in MBR2GPT tool can convert the disk without reinstalling. Run its validation first, and back up before converting.
- Old firmware. A BIOS update from the laptop maker can add TPM or UEFI options.
The dead end
The processor can't be changed in practice. If it's not supported, no amount of memory, storage or tuning will make the laptop eligible.
What are the honest options if your laptop doesn't qualify?
Stay on Windows 10
Regular security updates for Windows 10 ended on 14 October 2025. Microsoft offered a time-limited Extended Security Updates programme for home users, so check its current terms. Without updates, risk grows over time, which matters most for banking and work. If you stay, keep browsing minimal and the laptop updated in every other way. Our guide to Windows 10 end of support for old laptops covers this in more depth.
Switch to a lightweight Linux
Distributions such as Ubuntu or Linux Mint run well on older hardware and receive security updates. The trade-off is software: some Windows-only programs, including certain accounting and design tools, won't run natively.
Install Windows 11 anyway
Workarounds exist, but Microsoft states that unsupported PCs aren't guaranteed to receive updates, including security updates. We don't recommend this for a laptop used for banking, client data or anything important.
Replace the laptop
If the cost of keeping an old machine going exceeds its value, replacement is reasonable. Selling your old laptop offsets the cost, and a tested refurbished laptop can be much better value than a new budget one. Our guide to repairing or replacing an old laptop shows how to weigh it.
How do you upgrade safely if your laptop qualifies?
- Back up first. Upgrades through Windows Update keep your files by default, but a backup is cheap insurance.
- Update the BIOS and drivers from the laptop maker's support page.
- Free up space. The installer needs plenty of room and will tell you if you're short.
- Upgrade through Windows Update rather than third-party tools, so you receive the supported experience.
- Check devices afterwards. Open Device Manager and look for yellow warning icons, and test WiFi, audio and graphics.
- Keep the rollback window in mind. For a limited time, usually ten days, Windows lets you go back to Windows 10. Don't clean up the old Windows files until you're sure.
- Consider an SSD. A laptop that runs from a hard drive will feel slow on any modern Windows, so budget for the swap.
Frequently asked questions
Is Windows 11 free for my old laptop?
Microsoft has offered the upgrade at no charge to eligible Windows 10 PCs. Check Settings, Windows Update to see whether your laptop is offered it. If it isn't, it doesn't meet the requirements.
Will Windows 11 slow down my old laptop?
On a qualifying laptop with 8GB of RAM and an SSD, it generally runs well. On a hard drive with 4GB of RAM it can feel sluggish, which is why a drive or memory upgrade often goes hand in hand with the move.
Can I use Windows 11 if my laptop only has TPM 1.2?
Not officially. Microsoft requires TPM 2.0. Many laptops with an older-looking chip have a firmware TPM 2.0 that's simply switched off, so check the BIOS before giving up.
Will I lose my files when I upgrade?
The standard upgrade keeps your files and apps by default. Back up anyway, because upgrades can fail halfway, and a backup makes failure harmless.
