Upgrade TPM from 1.2 to 2.0 on HP ProBook 450 G2: A Guide

Select Language:

If you’re looking to upgrade your notebook to Windows 11 but have run into some obstacles, don’t worry; you’ve got options. First, let’s clarify the hardware requirements. Your existing notebook may not support the TPM firmware upgrade from version 1.2 to 2.0 unless it’s a model like the 450 G3 or newer. Even if you manage to upgrade the TPM, if your processor isn’t at least an Intel 8th generation core, you won’t meet Microsoft’s minimum requirements for running Windows 11.

However, if you’re content with your current PC and want to upgrade from Windows 10 to Windows 11 (24H2), here’s a simple, step-by-step guide that can help you achieve that smoothly.

Start by checking out a helpful video tutorial that guides you on how to install Windows 11 on unsupported PCs. It’s straightforward and effective, making it my recommended method after trying various approaches over the years. Here’s the link you’ll need:

Next, you’re going to need the Windows 11 24H2 ISO file. You can download it directly from Microsoft using this link:

To handle the ISO file, I recommend downloading the free file utility called 7-Zip. Here is the link for that; just grab the top option for 64-bit systems:

Keep in mind that if you use this method, you’ll need to repeat the steps each time Microsoft releases a new Windows 11 build. Since these updates are typically rolled out each October, be prepared for that. However, your PC will still receive monthly cumulative updates and other support, so not all is lost.

The minor inconvenience of not receiving automatic updates shouldn’t be a deal-breaker. Plus, if you experience any issues with Windows 11 after upgrading, you have a 10-day grace period to revert back to Windows 10 as long as you keep the upgrade files intact. For guidance on how to do that, check this video:

In summary, even if your notebook has limitations, you can still move forward with an upgrade to Windows 11. Just follow these steps, and you’ll be on your way to enjoying the latest features without needing a brand-new computer. Happy upgrading!
