I am having issues with upgrading to Windows 11

Hello Marjorie G Kaplan!

From the symptoms described, the “This PC doesn’t meet the minimum requirements for Windows 11” message is almost always caused by one of a few checks failing—most commonly TPM 2.0 not enabled, Secure Boot not enabled, unsupported CPU, or disk/firmware set to Legacy/CSM with MBR instead of UEFI/GPT, rather than a missing Windows license key. A missing or unknown license does not block the upgrade check; hardware, firmware, and setup conditions do.

What to check first

1. Verify Windows 11 requirements with Microsoft’s official guidance and PC Health Check, then confirm TPM 2.0 and Secure Boot are actually enabled in firmware (BIOS/UEFI). Many custom builds have TPM off by default even when the motherboard supports it. In Windows, run tpm.msc and confirm “Specification Version 2.0,” and ensure Secure Boot is on in UEFI with CSM/Legacy disabled; drives should be GPT for UEFI boot. If “Compatible TPM cannot be found,” enable fTPM/TPM in BIOS and recheck.
2. Understand what “requirements not met” means. Microsoft explicitly warns that devices not meeting minimums may not be supported or receive updates, and the watermark/message appears when the system doesn’t comply. If the device is truly unsupported (e.g., older CPU or TPM 1.2), Microsoft advises remaining on Windows 10 rather than forcing the upgrade.

Try Microsoft’s general upgrade fixes if requirements should be met. Remove nonessential peripherals, update BIOS/firmware and drivers, uninstall third‑party antivirus, free disk space, and run Windows Update to current before upgrading. These are standard first steps for upgrade blocks that aren’t hard requirement failures.

How to proceed if the hardware is compatible

If the PC meets requirements but Windows Update still blocks the upgrade, try one of these Microsoft-approved routes: use the Windows 11 Installation Assistant, or mount the official Windows 11 ISO and run setup.exe for an in‑place upgrade (optionally choose to not check for updates during setup if updates are stalling the process). This often bypasses ambiguous Windows Update blocks on otherwise‑eligible systems.

If the hardware is not officially supported

Microsoft documents that installing on unsupported hardware is not recommended and may not receive updates. There is an official registry method that loosens checks for an in‑place upgrade when TPM 1.2 is present (AllowUpgradesWithUnsupportedTPMOrCPU=1), but this still requires at least TPM 1.2 and carries support/update caveats. Independent guides and tools can bypass broader checks, but doing so is at one’s own risk; Microsoft’s stance remains to stay on Windows 10 on unsupported devices.

License considerations

Not knowing the existing Windows product key does not cause the “minimum requirements” error, and it does not prevent the upgrade compatibility check. Activation/licensing is separate from the hardware eligibility gate. As long as the current Windows is activated (often via a digital license tied to the hardware), the upgrade path is not blocked by the product key’s visibility. Use Settings > Activation to confirm activation status; this is unrelated to the TPM/Secure Boot/CPU checks.

Practical checklist

In BIOS/UEFI: Enable TPM (fTPM/PTT), enable Secure Boot, disable CSM/Legacy, and ensure the boot drive is GPT/UEFI. Then re-run the Windows 11 check or Setup. Community reports frequently resolve the error by disabling CSM and ensuring Secure Boot/TPM are enabled, especially on custom builds.

In Windows: Run tpm.msc to verify “Specification Version: 2.0,” confirm Secure Boot state, update drivers/BIOS, unplug nonessential devices, temporarily remove third‑party AV, and ensure enough free space. Then try Installation Assistant or ISO in‑place upgrade.

If still blocked and the CPU/TPM version is unsupported, consider staying on Windows 10 per Microsoft’s recommendation, or proceed with the official limited bypass only if at least TPM 1.2 is present, understanding support/update implications.

Best regards,
