Can My PC Run Windows 11? How to Check in 5 Minutes (and What to Do If It Can’t)
Nobody wakes up excited to research firmware settings. You just want to know whether your computer has a future. So let’s answer the question everyone eventually types into a search bar: can my PC run Windows 11?
It comes down to a short list of Windows 11 requirements. Two of them, TPM 2.0 and Secure Boot, hide in corners of your PC you’ve probably never visited, and they cause most of the confusing “no” results. But I have the good news! A proper Windows 11 compatibility check takes about five minutes, costs nothing, and changes nothing on your machine.
Below: Microsoft’s checker, the manual checks, and what to do when your PC says no.
Windows 11 Requirements in Plain English
Microsoft keeps the official list on its Windows 11 specifications page and in a Microsoft Learn article. On paper, the Windows 11 minimum requirements look modest. Here they are without the jargon:
| Requirement | What it actually means | Where to check |
| Processor (CPU) | 1 GHz, 2+ cores, 64-bit – and on Microsoft’s list of supported processors | Settings > System > About |
| RAM | 4 GB minimum; 8 GB feels comfortable | Settings > System > About (“Installed RAM”) |
| Storage | 64 GB drive, plus free space for the upgrade | File Explorer > This PC |
| UEFI + Secure Boot | Modern firmware that blocks tampered startup code | System Information (msinfo32) |
| TPM 2.0 | A security chip, often built into the processor | tpm.msc |
| Graphics | DirectX 12 with a WDDM 2.0 driver – almost any recent GPU | dxdiag |
| Display | 720p, larger than 9 inches | Any normal monitor passes |
| Internet + account | Needed to set up Windows 11 Home | – |
If one row deserves a highlighter, it’s the processor. A fast chip isn’t automatically a supported one, and Microsoft notes you can’t upgrade clock speed or core count. As a rough rule, Intel 8th Gen or newer and AMD Ryzen 2000 or newer make the cut. Older chips are where the heartbreak happens.
Check With the PC Health Check App
The official way to check if PC can run Windows 11 is Microsoft’s free PC Health Check app. It gives a plain yes or no to can my PC run Windows 11? and changes nothing on your system.
Download and Run the App
- Open Start and type PC Health Check – many Windows 10 PCs already have it.
- If not, download it from aka.ms/GetPCHealthCheckApp and install it.
- Open the app and click Check now in the “Introducing Windows 11” box.
- Wait a few seconds for the results window.
How to Read the Results
When the Windows 11 compatibility check finishes, you’ll see one of these verdicts:
| What you see | What it means | What to do next |
| “This PC meets Windows 11 requirements” | You’re good to go | Skip to “How to Upgrade Safely” |
| TPM or Secure Boot flagged | Usually just switched off | Turn it on in BIOS/UEFI (see below) |
| “Processor isn’t currently supported” | A hardware limit, not a setting | See “Your PC Failed the Check” |
| Storage or RAM flagged | Too little space or memory | Free up space or consider an upgrade |
Click See all results for details. Just swapped a part? Give it a day – Windows Update can take up to 24 hours to refresh eligibility.
Check TPM 2.0 and Secure Boot Manually
Sometimes PC Health Check just says TPM “must be supported and enabled.” Is the chip missing, or just off? Two built-in tools tell you.
Check TPM With tpm.msc
- Press Win + R, type tpm.msc and press Enter.
- Under “TPM Manufacturer Information,” look for Specification Version. You want to see 2.0.
- “Compatible TPM cannot be found”? Don’t panic – on most recent PCs, it’s just switched off in the firmware.
Check Secure Boot in System Information
- Press Win + R, type msinfo32 and press Enter.
- In System Summary, BIOS Mode should say UEFI. “Legacy” is a red flag.
- Check Secure Boot State: On is ideal, Off is an easy fix, and Unsupported usually means Legacy mode.
Check Your Processor
Open Settings > System > About and read the processor name. On Intel chips, the first digit after the dash is usually the generation: a Core i5-7200U is 7th gen (not supported), a Core i5-8250U is 8th gen (fine). On the AMD side, Ryzen 1000 misses out.
One wrinkle: Windows 11 requirements are set per release, with a separate processor list for each version – see the Intel list for 25H2 and the AMD list for 25H2. If your exact model isn’t listed, you have an unsupported CPU, and no setting will change that.
Your PC Failed the Check – What Now?
Take a breath – many “failures” are just a setting nobody turned on:
| What failed | Your best move |
| TPM or Secure Boot is off | Switch it on in the firmware (free, 10 minutes) |
| BIOS Mode shows “Legacy” | Convert the disk with Microsoft’s MBR2GPT tool, then switch to UEFI (advanced – back up first) |
| Unsupported CPU, everything else passes | Stay on Windows 10 with ESU and plan calmly |
| Old PC: no TPM, under 4 GB of RAM | ChromeOS Flex, Linux, or a new PC |
Turn On TPM and Secure Boot in BIOS/UEFI
It sounds scarier than it is:
- Go to Settings > Update & Security > Recovery and click Restart now under Advanced startup.
- Choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
- Look for Intel PTT (Platform Trust Technology), AMD fTPM or “Security Device Support,” and enable it.
- Find Secure Boot (usually on the Boot or Security tab) and set it to Enabled.
- Save and exit (often F10), then run PC Health Check again.
BIOS settings are named differently by every manufacturer, so check your manual if something’s missing. And if BIOS Mode says Legacy, don’t flip to UEFI before converting the disk, or Windows won’t start.
Keep Windows 10 With ESU
If the processor is your only problem, you don’t have to decide today. The Windows 10 ESU program keeps security updates coming until October 12, 2027 – a year later than first planned (see our Windows 10 ESU end date guide).
Enroll free by syncing settings through Windows Backup, with 1,000 Microsoft Rewards points, or for a one-time $30 (price checked Sep 29, 2026). Your PC needs Windows 10 version 22H2 with the latest updates.
Remember, ESU is a bridge, not a destination: security patches only, no new features.
Buy a New PC or Try ChromeOS Flex
Shopping for a new PC? Anything sold with Windows 11 clears the bar. “Copilot+” only matters for on-device AI (it needs a 40+ TOPS NPU). My honest advice: put 16 GB of RAM and an SSD above an AI sticker.
If your old laptop mostly lives in a browser, ChromeOS Flex is free, and Google says it runs on most computers made in the last decade. Check the certified models list for your model’s end-of-support year, and try it from a USB stick first. Linux Mint or Ubuntu work too.
Unsupported Workarounds: Why We Don’t Recommend Them
Registry tweaks and tools like Rufus can force Windows 11 onto old hardware. But Microsoft warns such PCs may malfunction, aren’t guaranteed security updates, and compatibility damage isn’t covered by warranty.
If you try anyway, treat it as a weekend project, not your banking PC.
Is the Windows 11 Upgrade Still Free?
Yes, the free upgrade is still on the table as of September 29, 2026, for eligible PCs with a genuine Windows 10 license. Home goes to Home, Pro to Pro.
Existing PCs get version 25H2, with 26H2 expected within days as a small update that extends support. Ignore 26H1 – it only ships on select new devices.
How to Upgrade Safely
Back Up Your Files First
An upgrade to Windows 11 keeps your files and apps, but I’d still back up files first. Ten boring minutes beat one bad evening.
Windows Backup syncs folders to OneDrive, but free accounts get only 5 GB. For big photo libraries, use an external drive, and jot down your license keys.
Start the Upgrade From Windows Update
- Open Settings > Update & Security > Windows Update and click Check for updates.
- If Windows 11 is offered, click Download and install.
- Plug in, make a cup of tea, and expect about an hour.
Changed your mind? You have 10 days to roll back in Settings > System > Recovery.
