To fix the “This PC doesn't currently meet all the system requirements for Windows 11” error, first enable TPM 2.0 in the BIOS/UEFI, as it is a key requirement and often disabled by default even on supported hardware. Next, ensure your system meets other specifications like secure boot, CPU compatibility, RAM, storage, and screen size. Finally, after making necessary adjustments, retry the Windows 11 installation or upgrade.

You’ve probably seen the message “This PC doesn't currently meet all the system requirements for Windows 11” when trying to upgrade or install Windows 11. The good news is, this doesn’t always mean your PC can’t run it — just that something isn’t quite up to spec yet. Let’s go over how to fix that.

Check if Your CPU Is on Microsoft’s Supported List

Windows 11 has a stricter list of supported processors than Windows 10. Even if your CPU is relatively recent, it might not be officially supported.

• You can check your CPU model by opening Task Manager > Performance tab.
• Then compare it with Microsoft’s official list of supported CPUs.
• If your processor isn’t listed, you might still be able to install Windows 11 unofficially, but updates could stop working later.

Some users have found success by upgrading BIOS or microcode, especially on older Intel CPUs. If you're unsure what to do, look up your motherboard model and see if there's a firmware update available from the manufacturer.

Enable TPM 2.0 in the BIOS/UEFI

TPM (Trusted Platform Module) 2.0 is a key requirement for installing Windows 11. It’s often disabled by default, even if your hardware supports it.

Here’s how to check:

• Restart your computer and enter the BIOS/UEFI setup (usually by pressing Del, F2, or Esc during boot).
• Look for options like "Security," "TPM," or "PTT" in the menu.
• Make sure TPM 2.0 is enabled. If you don’t see TPM but see PTT, enable that instead — it’s a software version of TPM and works for Windows 11.

If you’re not comfortable doing this yourself, a quick search using your motherboard model plus “enable TPM 2.0” should give you step-by-step guides.

Make Sure Secure Boot Is Turned On

Secure Boot helps protect your system from malware by only allowing trusted software to run at startup. Windows 11 requires it to be enabled.

To check:

• Enter BIOS/UEFI again.
• Find the Secure Boot option — usually under the Boot or Security tab.
• Set it to Enabled.

Note: Some motherboards hide Secure Boot behind an “OS Type” setting (like selecting “Other OS” vs “Windows UEFI”). If Secure Boot seems grayed out, try changing that first.

Bypass Requirements Using Setup Trick (Not Officially Supported)

If your hardware doesn’t fully meet the requirements and you still want to proceed, there’s a way around — though keep in mind this is unsupported and may lead to issues down the road.

• When running the Windows 11 installer, you’ll get the warning screen. Press Shift F10 to open Command Prompt.
• Type notepad and hit Enter.
• Open the file explorer inside Notepad and navigate to the installer folder (C:\$WINDOWS.~BT\Sources\appraiserres.dll is a common path).
• Delete or rename this file.
• Close everything and click “Back” then try again — the error should no longer block you.

Again, this method works for some people, but Microsoft might patch it in future updates.

That’s about it. Most fixes come down to checking TPM, Secure Boot, and CPU support. A few tweaks in BIOS and maybe a workaround during setup, and you should be able to move forward.
