Upgrade to Windows 11 on Unsupported Hardware (24H2)

Though Windows 11 is largely identical to Windows 10 internally, Microsoft changed the hardware requirements and will block the upgrade on many PCs that run Windows 10 successfully. We discuss these requirements in Windows 11 and Copilot+ PC Hardware Requirements and Recommendations. In this chapter, we will focus on how you can circumvent Microsoft's blockers.
To be fair, some of the requirements are reasonable. For example, we don't believe you should install Windows 11 on a PC with a very old Intel, AMD, or Qualcomm microprocessor, or less than 8 GB of RAM or 256 GB of storage. But some other requirements are controversial because they seem largely arbitrary and designed solely to convince users to purchase new Windows 11-based PCs.
Consider the potential downsides
You should also consider the potential downsides to bypassing the hardware requirements. They are:

It's unsupported. You can't turn to Microsoft or your PC maker if you have software issues.
Microsoft might stop delivering updates. Microsoft warns that "if you proceed with installing Windows 11 [on unsupported hardware], your PC won't be entitled to receive updates." This is almost certainly a hollow threat. And years into the Windows 11 era, this has never happened.
Potential security issues. Microsoft argues that its processor and TPM requirements are for security reasons, but that's only partially true. If your PC has a TPM 1.2 or TPM 2.0 chip and an unsupported microprocessor, it will be no less secure than Windows 11 running on fully supported hardware.
Annoying desktop watermark. Microsoft says it might display a watermark overlay on the desktop when you use Windows 11 on an unsupported PC. And while it did test displaying such a watermark years ago, it has never done this to its customers, at least not yet. If it does, no worries: You will be able to work around it, and we will document how to do so in this book.

Upgrade to Windows 11 on an unsupported PC
Since your PC is unsupported, you will not be offered the Windows 11 upgrade normally via Windows Update. So you will need to download the latest Windows 11 installation disc image file (in ISO format) and use that to manually upgrade your PC instead.

You obtain this file from the Microsoft website.

To download the ISO:

Scroll down to "Download Windows 11 Disk Image (ISO) for x64 devices" and expand the "Select Download" drop-down list.
Select the "Windows 11 (multi-edition ISO for x64 devices)" option and then click "Download Now."
After Microsoft validates your request, expand the "Choose one" drop-down list under the new "Select the product language" section, and select your language ("English (United States)" in our case).
Click "Confirm."
After Microsoft validates this request, a new "Download - Windows 11 English" (or similar) section appears. Click "64-bit Download" to finally download the 5.4 GB Windows 11 installation disc image file. Be sure to save the ISO file to a...
