Key Takeaways

To instal Windows 11 connected an unsupported PC, effort making nan PC supported by enabling TPM 2.0, Secure Boot, and switching to GPT. If those features cannot beryllium enabled connected your PC, you must usage a fewer registry hacks to unit Windows 11 to install.

Windows 11 has strict strategy requirements, but location are ways astir them. For example, it requires astatine slightest an 8th-generation Intel, AMD Zen 2, aliases Qualcomm 7 aliases 8 Series CPU — but you tin instal Windows 11 connected PCs pinch older CPUs.

Should You Upgrade an Unsupported PC?

First, let's beryllium clear: If you're connected nan fence, we urge against upgrading an unsupported PC to Windows 11. Windows 10 will beryllium officially supported pinch information updates until October 2025.

If nan instrumentality reports your PC is unsupported, nan process you request to travel will dangle connected nan problem it reports. You whitethorn conscionable person to alteration a mounting successful your PC's UEFI firmware (the modern replacement for nan BIOS) to make your PC supported — aliases nan process whitethorn beryllium much involved.

The PC Health Check app saying a PC doesn't presently meet Windows 11's minimum requirements.

How to Enable TPM 2.0

Windows 11 officially requires TPM 2.0. (However, there's an easy measurement to instal Windows 11 if your PC only has TPM 1.2, which we'll screen below.)

If nan instrumentality reports that your machine doesn't person TPM, there's a chance your PC does person TPM — but it whitethorn beryllium abnormal by default.

To check for and alteration TPM 2.0, you will request to participate your computer's UEFI firmware settings (the modern replacement for nan BIOS). Look for an action named thing for illustration "TPM," "Intel PTT," "AMD PSP fTPM," aliases "Security Device." You whitethorn find it successful nan main UEFI settings paper aliases successful a paper named thing for illustration "Advanced," "Trusted Computing," aliases "Security."

How to Enable Secure Boot

If PC Health Check reports your machine isn't utilizing Secure Boot, you should besides look successful UEFI firmware settings for a "Secure Boot" action and alteration it, if possible.

You whitethorn person abnormal Secure Boot to instal Linux, aliases it whitethorn person travel abnormal connected your motherboard. Modern Linux distributions for illustration Ubuntu and Fedora activity connected PCs pinch Secure Boot enabled, truthful you don't needfully person to disable this information characteristic to instal Linux.

If you are capable to alteration Secure Boot, re-run nan PC Health Check tool. You tin now upgrade usually — assuming Secure Boot was nan only problem.

How to Fix No UEFI (MBR Instead of GPT)

Windows 11 requires UEFI. Some older computers connection some modes: UEFI firmware aliases a accepted bequest BIOS. If you are presently utilizing a "traditional" MBR partitioning setup but your PC does connection UEFI arsenic an option, you will person to move to a GPT partition table to usage UEFI.

There are respective ways to do this. Microsoft's MBR2GPT tool whitethorn let you to person a thrust from MBR to GPT format. Microsoft warns that you should only do this if you cognize your PC supports UEFI, and that you whitethorn person to alteration settings successful your PC's firmware to make it footwear successful UEFI mode alternatively than bequest BIOS mode afterward.

Windows 11 will erase your Windows 10 strategy and group up your thrust successful GPT mode.

Registry Hack for Unsupported CPUs and/or Only TPM 1.2

If your only problem is that your machine has an unsupported CPU and/or that it only has TPM 1.2 alternatively of TPM 2.0, this is nan easiest problem to get around.

If you truthful choose, you tin get astir this regularisation pinch a elemental Windows Registry change. Making this alteration will origin Windows 11 to disregard nan CPU type cheque and instal moreover if only TPM 1.2 is present. However, this won't destruct different checks — for example, if your machine doesn't person a TPM astatine all, this registry alteration won't fto you upgrade.

The Windows Registry is complex, and you should beryllium observant what you add, edit, aliases delete successful it. You could origin problems pinch your Windows installation. If you're not comfortable editing nan registry, you whitethorn want to debar upgrading. However, arsenic agelong arsenic you travel our proposal here, you shouldn't person immoderate problems.

Enter nan reside successful nan Registry Editor's location bar.

Right-click successful nan correct pane, prime New > DWORD (32-bit) Value, and participate nan pursuing matter arsenic nan name:

Double-click "AllowUpgradesWithUnsupportedTPMOrCPU".

Double-click nan "AllowUpgradesWithUnsupportedTPMOrCPU" worth here, group it to "1", and click "OK."

Enter "1" and click "OK."

Want to skip nan registry-editing process? Download our Enable Unsupported Upgrades registry hack to execute nan alteration successful conscionable a fewer clicks.

This downloadable ZIP record contains 2 REG files: One that enables upgrades connected unsupported PCs (Enable Unsupported Upgrades.reg) and 1 that reverts nan alteration (Undo Enable Unsupported Upgrades.reg).

Bear successful mind that this only does 2 things: It makes Windows 11 disregard nan CPU requirement, and it lets Windows 11 instal pinch TPM 1.2 alternatively of TPM 2.0. It won't get astir different requirements. For example, if your PC doesn't person a TPM astatine each aliases has only a bequest BIOS alternatively of UEFI firmware, this registry mounting won't help.

PCs With No TPM astatine All, No UEFI, aliases Other Major Problems

If nan tips supra and nan registry hack aren't capable for your PC, now things commencement to get dicey. If your machine doesn't person a TPM astatine all, for example, it's really unsupported.
