Windows 10 will be EOL (End-Of-Life) in exactly one month on October 14th. Microsoft says you need a modern PC with TPM chip to run Windows 11, but this is not true. In this post I'll explain how to upgrade to Windows 11 without a TPM chip (or any other hardware requirement). As a bonus I'll help you setup Windows 11 in a more privacy friendly way using the "O&O ShutUp10++" software package.
Disclaimer: Make sure to backup your PC before you upgrade to Windows 11.
On the following link you can download the Windows 11 ISO for x64 in your favorite language:
https://www.microsoft.com/nl-nl/software-download/windows11
It will download a file named "Win11_24H2_EnglishInternational_x64.iso". You can right-click and mount this image to make it appear as a new disk in your PC. Then you can run the "setup.exe" from the disk to start the Windows 11 installer.
You can run the following batch script to bypass the Windows 11 (24H2) hardware checks. Open "notepad.exe" and paste the following:
Subscribe@echo off
reg delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\CompatMarkers" /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Shared" /f
reg delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\TargetVersionUpgradeExperienceIndicators" /f
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\HwReqChk" /v "HwReqChkVars" /t REG_MULTI_SZ /s "," /d "SQ_SecureBootCapable=TRUE,SQ_SecureBootEnabled=TRUE,SQ_TpmVersion=2,SQ_RamMB=8192" /f
reg add "HKLM\SYSTEM\Setup\MoSetup" /v "AllowUpgradesWithUnsupportedTPMOrCPU" /t REG_DWORD /d 1 /f
pause
Save this as the file "regfix.bat" on your desktop and right-click and "Run as Administrator", after confirmation the script is executed. After running this registry modification you can run the "setup.exe" from the Windows 11 ISO and it will skip the hardware compatibility test.
Rufus is a great tool that allows you to write the Windows 11 install media to a bootable USB drive. While doing this it can also apply many "fixes" to the installer, such as allowing to install without TPM. These fixes can be found in the "Windows User Experience" pop-up that it shows before writing the ISO to the disk.

NB: The bootable USB drive with Windows 11 that Rufus creates can also be used to upgrade Windows 10 PCs without TPM.
If you are booting directly from the ISO (in a VM for instance), then you can apply the procedure below to get a similar result.
During the installation press Shift-F10 and a Command Prompt window will appear. You can type the following commands:
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassTPMCheck /d 1 /t reg_dword /f
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassSecureBootCheck /d 1 /t reg_dword /f
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassRAMCheck /d 1 /t reg_dword /f
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassStorageCheck /d 1 /t reg_dword /f
reg add HKLM\SYSTEM\Setup\LabConfig /v BypassCPUCheck /d 1 /t reg_dword /f
Now the installer will install Windows 11 without hardware checks. When it asks to connect to a network type the following command:
start ms-cxh:localonly
You can now enter only a username and leave the password field(s) empty.
Windows 11 is not very privacy friendly, but this can be improved with a tool called "O&O ShutUp10++". Download and install "O&O ShutUp10++" and choose "Apply only recommended settings" and manually click the option "Disable extension of Windows search with Bing". The (recommended) option "Disable Windows Copilot+ Recall" is the most important one. If you don't disable this Windows 11 will send constant screenshots to Microsoft to profile what you are doing on your PC.

If you are like me, then you are thrilled that you can remove almost all standard installed apps in Windows 11. You can even remove Edge and install Firefox (or even LibreWolf) as your default browser. I can recommend to remove all installed Apps except for "Quick Assist" (in case you want to let somebody help you on your PC) and "Remote Desktop Connection" as these are useful to receive and give support to other users when using Windows.
