The fastest official way is Microsoft’s PC Health Check app. You can also verify key items in Windows settings and, if needed, in BIOS/UEFI before you spend time or money on an upgrade. ## What the check tells you A Windows 11 compatibility check answers one practical question: can this PC run Windows 11 under Microsoft’s current rules? It usually separates problems into two buckets: - hardware limits, such as an unsupported CPU, too little RAM, or too little storage - firmware or settings limits, such as TPM 2.0 being disabled or Secure Boot being off That matters because some failures are fixable with a BIOS/UEFI change, while others mean the PC does not meet Microsoft’s requirements. Before you plan an upgrade, compare the result against Microsoft’s current Windows 11 support page so you are checking against the latest requirements and release notes, not an old summary. ## How to run the compatibility check 1. Open Microsoft’s official PC Health Check app on the PC you want to upgrade. If you do not already have it installed, get it from Microsoft’s current support or download page and check that you are using the latest version offered there. The app is Microsoft’s simplest official compatibility check. 1. Run the app and choose the Windows 11 compatibility check. The app will show a pass or fail result. If it fails, it usually names the first requirement that needs attention, such as TPM, Secure Boot, memory, storage, or processor support. 1. If you want a quick cross-check in Windows, open Settings and review the device specs. Use the System page for installed RAM and basic device details, then confirm storage free space from the Storage page. These checks won’t replace Microsoft’s eligibility test, but they help you tell whether a failure is about capacity or about firmware/support. 1. Compare the result with Microsoft’s current Windows 11 requirements page. That page is the source of truth for supported CPUs, minimum memory, storage, TPM, and Secure Boot requirements. If the app and the support page disagree, trust the current Microsoft page and recheck the app version you used. ![A Windows PC has the PC Health Check app open on its screen.](https://tse1.mm.bing.net/th?q=Windows%20PC%20with%20PC%20Health%20Check%20app%20open&w=624&h=352&c=7) ## What the result means if you pass A pass usually means your PC is eligible to upgrade to Windows 11, assuming no other unusual blocker shows up later in setup. Before you start the upgrade, check Microsoft’s current Windows 11 support page for the exact release and any notes that apply to your device class. Microsoft can change support details, installation paths, and servicing notes over time, so it is better to confirm those details right before you upgrade than to rely on an older checklist. If the PC Health Check app says your device is ready, that is a strong sign the upgrade should proceed normally. It is not a promise that every app or driver on the machine will behave perfectly after the upgrade, so a pass answers compatibility, not every post-upgrade question. ## What to do if the check fails A failed check does not always mean the PC is dead-ended. Start with the easiest fixes first. - TPM off: many systems support TPM 2.0, but it may be disabled in firmware. Turn it on in BIOS/UEFI, then run the check again. - Secure Boot off: some devices have Secure Boot available but disabled. This is often a firmware setting, not a hardware limit. - Legacy boot mode: on some PCs, legacy boot can block Windows 11 eligibility. Switch to UEFI mode only if the motherboard and current installation support it. - Low storage: free up space or add storage if the machine is otherwise eligible. - Unsupported CPU: this is usually the hardest stop. If Microsoft does not support the processor for Windows 11, firmware changes will not fix that. If you plan to change firmware settings, do that before you run the check again. If the machine cannot expose TPM 2.0 or Secure Boot in firmware, or the CPU is not on Microsoft’s current supported list, the PC may not be eligible for a normal upgrade path. ## Quick ways to verify the tricky parts These checks help you tell the difference between a settings problem and a real hardware limit. ### Confirm TPM Open the Windows TPM management screen. If TPM is present and version 2.0 is shown, that part is likely fine. If Windows says no compatible TPM was found, the feature may be disabled in firmware or missing from the device. ### Confirm Secure Boot Open System Information and look for the Secure Boot State entry. If it says On, Secure Boot is enabled. If it says Off or Unsupported, check the firmware setup first; some older systems simply do not support it. ### Confirm system type Check whether Windows is 64-bit. Windows 11 requires a 64-bit environment, so a 32-bit Windows install will not qualify for a normal Windows 11 upgrade. ### Confirm RAM and storage Use Settings to check installed memory and available storage. If you are short on storage, free space can sometimes fix the problem. If RAM is below Microsoft’s minimum requirement for the current release, that is usually a hardware limit on the existing machine. If one of these checks looks wrong, fix the setting in BIOS/UEFI if the hardware supports it, then rerun PC Health Check. If the check still fails after the settings are corrected, the remaining blocker is usually hardware support, not a Windows setting. ## Conclusion If PC Health Check passes and the current Microsoft support page matches what you saw, your PC is likely ready for a normal Windows 11 upgrade. If it fails, the result usually tells you whether you need a firmware change, more storage, or a different PC. ## Frequently Asked Questions ### Can I use Windows 11 if PC Health Check says my CPU is unsupported? Usually not through Microsoft’s normal supported upgrade path. If the processor is not on Microsoft’s current supported list, changing firmware settings will not make it eligible. Check Microsoft’s current support page before deciding what to do next. ### Do I need to enter BIOS/UEFI before checking compatibility? Not always. Start with PC Health Check or the Windows settings checks. Go into BIOS/UEFI only if the result points to TPM, Secure Boot, or a boot-mode issue.
