Windows 11 requirements include the usual CPU, RAM, storage, and display basics, but they also include hardware security requirements such as UEFI, Secure Boot capability, and TPM 2.0. Those security checks are why some otherwise capable Windows 10 PCs fail eligibility.
This guide applies to anyone checking whether a Windows 10 PC can upgrade to Windows 11 or buying a PC that needs Windows 11 support.
Does This Affect You?
If PC Health Check says your computer does not meet Windows 11 requirements, it may be failing only one setting or component. TPM and Secure Boot are often present but disabled on PCs from the last several years.
Windows 11 Requirements in Plain Terms
- Processor: A compatible 64-bit CPU with at least two cores at 1 GHz or faster, from Microsoft’s supported processor list. In practice that usually means Intel 8th-gen Core or newer, or AMD Ryzen 2000-series or newer.
- RAM: At least 4 GB.
- Storage: At least 64 GB.
- Firmware: UEFI firmware that is Secure Boot capable.
- TPM: Trusted Platform Module 2.0, either as a hardware chip or firmware feature built into the processor/platform.
- Graphics: DirectX 12 or later with a WDDM 2.0 driver.
- Display: Larger than 9 inches with at least 720p HD resolution.
Check the Exact Requirement That Failed
- Download Microsoft’s official PC Health Check app.
- Open it and click Check now under Windows 11 eligibility.
- Read the specific blocker it reports, such as TPM 2.0, Secure Boot, CPU support, RAM, or storage.
- If TPM or Secure Boot is listed, check BIOS/UEFI settings before assuming the hardware cannot support Windows 11.
What to Do About Each Blocker
- TPM or Secure Boot: Often fixable by enabling the feature in BIOS/UEFI. Follow the PC or motherboard maker’s instructions.
- Processor: Usually not fixable with a setting. Unsupported CPU generation means Windows 11 is not officially supported on that PC.
- RAM or storage: Often fixable by adding memory, freeing disk space, or replacing a small drive.
- After all checks pass: Windows 11 should appear through Settings > Windows Update when Microsoft offers it to that device.
Requirement Context
TPM and Secure Boot Are About Security
These features are not speed upgrades. They help Windows protect startup integrity and encryption/credential features at the hardware level.
CPU Rules Are About Support Too
Some older CPUs may feel fast enough but are excluded because Microsoft does not guarantee the same driver, reliability, and security-feature support on them.
Windows 10 Is Still an Option Until Support Ends
If a PC cannot meet the requirements, staying on Windows 10 can be reasonable while it remains supported. Plan hardware replacement before security updates end.
Unsupported Installs Carry Risk
Microsoft documents unsupported installation paths but warns that unsupported PCs may not receive all updates and are not guaranteed reliable. Avoid depending on that for a primary machine.
