How to Check If Your PC Can Run Windows 11: Complete Compatibility Guide
Windows 11 introduced a modern interface, updated security features and several changes to the Windows experience.
However, not every computer that runs Windows 10 meets the official Windows 11 hardware requirements.
Before upgrading, it is important to check whether your computer is compatible.
In this guide, we will explain the main requirements and show you how to check your PC.
1. Check Your Processor
Windows 11 requires a compatible 64-bit processor with at least two cores and a supported clock speed of 1 GHz or faster.
However, meeting the speed and core requirements alone is not enough.
Your processor must also appear on Microsoft's supported processor list for the relevant Windows 11 version.
Check the official list:
AMD users should check Microsoft's supported AMD processor list as well.
2. Check Your RAM
The minimum RAM requirement for Windows 11 is 4 GB.
However, minimum requirements do not guarantee a smooth experience with every application.
For everyday multitasking, additional memory can be beneficial.
To check your RAM:
Press Ctrl + Shift + Esc.
Open Task Manager.
Select Performance.
Click Memory.
Your installed memory will be displayed.
3. Check Available Storage
Windows 11 requires a storage device with at least 64 GB capacity.
However, additional free space is necessary for updates, applications and personal files.
To check your available storage:
Open File Explorer.
Select This PC.
Review the free space on your system drive.
A drive with very little free space may cause update and installation problems.
4. Check TPM 2.0
Trusted Platform Module 2.0 is one of the important Windows 11 security requirements.
To check it:
Press Windows + R.
Type
tpm.msc.Press Enter.
If your computer supports TPM and it is enabled, Windows should display the TPM information.
Look for Specification Version 2.0.
If Windows reports that a compatible TPM cannot be found, check your motherboard or laptop manufacturer's documentation.
Some systems support firmware-based TPM but have it disabled in firmware settings.
5. Check Secure Boot Support
Windows 11 requires UEFI firmware with Secure Boot capability.
You can check the current boot configuration:
Press Windows + R.
Type
msinfo32.Press Enter.
Find BIOS Mode and Secure Boot State.
Your system should use UEFI and support Secure Boot.
Changing firmware settings without understanding the current boot configuration can make Windows unbootable, so consult your computer manufacturer before making changes.
6. Check Your Graphics Compatibility
Windows 11 requires a DirectX 12-compatible graphics solution with a WDDM 2.0 driver.
To check your graphics information:
Press Windows + R.
Type
dxdiag.Press Enter.
Open the Display tab.
Review your graphics and driver information.
Also check the graphics manufacturer's official driver support information.
7. Use Microsoft's PC Health Check Tool
Microsoft provides PC Health Check to help determine whether a computer meets Windows 11 requirements.
Download it from Microsoft's official website:
https://aka.ms/GetPCHealthCheckApp
Install the application and select the Windows 11 eligibility option.
It can identify common compatibility problems.
8. What If Your PC Is Not Compatible?
If your PC does not meet the official requirements, investigate the exact reason.
Possible issues include:
Unsupported processor.
TPM 2.0 disabled or unavailable.
Secure Boot configuration.
Insufficient memory.
Inadequate storage.
Unsupported graphics or firmware configuration.
Do not use unofficial bypass tools without understanding the risks.
Installing Windows 11 on unsupported hardware is not recommended by Microsoft and may result in compatibility issues or lack of guaranteed updates and support.
9. Should You Upgrade From Windows 10?
The decision depends on your hardware, software requirements and security needs.
Windows 10's standard support ended on October 14, 2025. Eligible users may have additional security options through Microsoft's Extended Security Updates program.
If your PC is officially compatible, Windows 11 may be a suitable upgrade.
If it is not compatible, consider supported alternatives rather than forcing an installation.
Check Microsoft's current support information before making a decision.
Final Thoughts
Checking Windows 11 compatibility before upgrading can help prevent installation problems.
Review your processor, RAM, storage, TPM 2.0, Secure Boot and graphics requirements.
Use Microsoft's official PC Health Check tool and manufacturer documentation to make an informed decision.
A successful upgrade begins with understanding your computer's hardware.
