Sometimes it's Mission Impossible.
Many tools can let you install Windows 11 if the hardware is not supported and monthly updates might work fine.
However yearly feature updates will fail to install if hardware requirements are not met.
This is why IoT (24H2/2024) editions are mentioned so that you can get official support on future feature upgrades.
Upgrade Windows 10 Home, Pro, etc editions to Windows 11 IoT Enterprise (GAC/LTSC) 2024 while keeping files and apps.
You can install the officially supported Windows 11 24H2 IoT editions on a system without a TPM, Secure Boot, and UEFI.
Please click here for more information.
Download any Windows 11 24H2 (For GAC) or Enterprise LTSC 2024 (For LTSC) Links below.
Right-click on the downloaded ISO file, Open With > Windows Explorer
A new DVD drive will appear in Windows Explorer, which means the installation image has been mounted successfully.
Next make a text file call it PID.txt insert the version below.
For GAC version
[PID]
Value=XQQYW-NFFMW-XJPBH-K8732-CKFFD
For LTSC version
[PID]
Value=CGK42-GYN6Y-VD22B-BX98W-J8JXD
Insert this file into the sources folder.
Now open the command prompt as admin and enter,
For GAC
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v EditionID /d IoTEnterprise /f
For LTSC
reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v EditionID /d IoTEnterpriseS /f
Now quickly go into that DVD drive and run setup.exe, and continue until you reach the final confirmation screen.
Don't delay at this step, otherwise it won't show an option to keep files and apps.
Make sure it says "Keep personal files and apps" on the final screen.
Then you can continue the process and wait until it is done.
