The new operating system Windows 11 is already officially available to everyone. and if you do decide to give it a try, this article will help you figure out how to upgrade to Windows 11 or install from scratch.

Windows 11 has strict system requirements but there are ways to work around them. For example, this requires an Intel, AMD Zen 2, or Qualcomm 7 or 8 series processor of at least 8th generation, but you can install Windows 11 on PCs with older processors. which will be discussed below

But there are some main points we should discuss first.

How to find out why your computer is not supported?

You can check if Windows 11 supports your computer by downloading and running the Microsoft PC Health Check app.

  • If your computer is supported,   it’s easy to upgrade to Windows 11 . This can be done in just a few clicks.
  • If Windows 11 does not officially support your computer, the PC Health Check will say that it “does not currently meet the system requirements for Windows 11,” and will tell you why.
  • If the tool reports that your computer is not supported, the process you need to follow will depend on the problem it is reporting. You may just have to change a setting in your PC’s UEFI firmware (modern BIOS replacement) in order for your PC to be supported – or the process may be more complicated.

Should you upgrade an unsupported computer?

We do not recommend upgrading an unsupported computer to Windows 11. It’s because, with the method of installing or upgrading to Windows 11, Microsoft also gave the warning about it:

“Your device may not function properly due to compatibility issues. Devices that do not meet these system requirements will no longer be guaranteed to receive updates, including but not limited to security updates”

warns Microsoft

How do I install Windows 11 on an incompatible PC?

Ways to make your PC Compatible to Windows 11

  • Enable TPM 2.0
  • Enable secure boot
  • Hacking the registry for unsupported processors and / or TPM 1.2 only

Enable TPM 2.0

Windows 11 officially requires TPM 2. However, there is an easy way to install Windows 11 if you only have TPM 1.2 installed on your computer, which we will discuss below.

If the tool reports that your computer does not have a TPM, there is a chance that your computer has a TPM, but it may be disabled by default.

How to enable TPM 2.0 and Secure Boot in BIOS to Install Windows 11

To check and enable TPM 2.0, you will need to enter your computer’s UEFI firmware settings (modern BIOS replacement). Look for an option with a name like TPM, Intel PTT, AMD PSP fTPM, or Security Appliance. You can find it in the main UEFI settings menu or under the menu titled Advanced, Trusted Computing, or Security.

For more information, run an online search for your computer model name and “enable TPM” or consult its official documentation. (If you’ve built your own computer, look for your motherboard model name instead)

You may also need to install a UEFI update for your computer or its motherboard. Manufacturers release updates that either include TPM 2.0 by default or add support for it.

It may even be possible to upgrade TPM 1.2 to TPM 2.0 with a firmware update on some PCs; it depends on the manufacturer of your hardware and system. Check with your computer (or motherboard) manufacturer for more information on updates for Windows 11.

After enabling TPM, rerun the PC Health Checker. You should be able to update normally if that was your only problem.

How to enable secure boot

Windows 11 requires UEFI. Some older computers offer both modes: UEFI firmware or traditional legacy BIOS. If you are currently using a “traditional” MBR partition setup, but your computer offers UEFI as an option, you will have to switch to the GPT partition table in order to use UEFI.

There are several ways to do this. Microsoft MBR2GPT tool can let you convert the disk from MBR format to GPT format. Microsoft warns that you should only do this if you know that your computer supports UEFI and that you might need to change settings in your PC’s firmware so that it subsequently boots in UEFI mode rather than legacy mode. BIOS.

If this is your only problem, the easiest thing to do is to do a clean install. First, be sure to back up your files (we still recommend backing up your files before updating).

Then use the  Microsoft Media Creation Tool to create a bootable Windows 11 USB stick. Now use your installation media to perform a clean install of Windows 11 by wiping your disk – you may need to put your computer’s firmware into UEFI mode first. Windows 11 will wipe your Windows 10 system and set up your disk in GPT mode.

Hacking the registry for unsupported processors and / or TPM 1.2 only

If your only problem is that your computer has an unsupported CPU and/or that it only has TPM 1.2 instead of TPM 2.0, this is the easiest to work around.

If you wish, you can work around this limitation simply by modifying the Windows Registry. Making this change will cause Windows 11 to ignore checking and installing the CPU version, even if only TPM 1.2 is present.

However, this will not resolve other checks – for example, if your computer does not have TPM at all, this registry change will prevent you from performing an update.

The Windows Registry is complex and you have to be careful what you add, edit, or delete in it. You can cause problems with your Windows installation. If you are uncomfortable with editing the registry, you can avoid updating. However, if you follow our advice, you shouldn’t have any problems.

How to Change Registry

  • First, open the registry editor. You can press Windows + R, type “regedit” and Press Enter, or type “registry” in the Start menu search box and click on the “Registry Editor” shortcut.
  • Enter the following address in the address bar in the Registry Editor window (or navigate to it in the left pane:
  • Right-click in the right pane, select New> DWORD (32-bit) Value and enter the following text for the name:
  • Double click the value “AllowUpgradesWithUnsupportedTPMOrCPU” here, set it to “1” and click “OK“.

This downloadable zip file contains two .reg files: one that allows updates to be performed on unsupported computers (Enable Unsupported Upgrades.reg) and the other to undo the change (Undo Enable Unsupported Upgrades.reg).

Just double-click the “Include Unsupported Upgrades.reg” file and agree to add the information to your registry. If you want to undo the change, double-click the undo file.

These files work the same way as the registry hack described above — they simply set the AllowUpgradesWithUnsupportedTPMOrCPU parameter to 1 (to enable unsupported updates) or 0 (to return to the default setting).

  • For the changes to take effect, restart your computer before continuing.

You can now download and run  Windows Setup Assistant from Microsoft’s website to upgrade your computer to Windows 11 as if it had a supported CPU or TPM 2.0. You just need to agree with the warning first.

PC without TPM, no UEFI or other major issues

If the above tips and registry hack are not enough for your PC, things are now risky. For example, if your computer doesn’t have TPM at all, then it really isn’t supported.

What does this mean? Well, Microsoft provides an official way to install Windows 11, for example with older CPUs and TPM 1.2 chips. You just need to flip the registry setting. It’s not supported, but Microsoft is helping you with that.

It is reported that there are ways to install Windows 11 even if you don’t have TPM 1.2 or UEFI. But this is not actually supported – you are even more likely to run into bugs and not receive security updates in the future if you bypass even these basic requirements.

We’ve also seen mixed reports of success from people following these tricks. Even if it works for you, updating after a few months could cause your PC to show up as a blue screen, break your operating system, and force you to reinstall Windows 10.

We recommend that you do not follow any of these extreme tricks – you get yourself into trouble. Windows 10 will work fine until October 2025, and by then you will probably need a new computer if your current computer is too old even for TPM 1.2.
