Windows 10 (IoT) Enterprise LTSC 2021
Microsoft releases Windows 10/11 in two servicing channels.
1- GAC (General Availability Channel) (i.e. Home, Pro, Enterprise). It will reach the end of support on October 14, 2025.
2- LTSC (Long-Term Servicing Channel) (i.e. Enterprise LTSC, IoT Enterprise LTSC). Windows 10 Enterprise LTSC 2021 will reach the end of support on Jan 12, 2027 and Windows 10 IoT Enterprise LTSC 2021 will reach the end of support on Jan 13, 2032
The solution is simple. You can just use the Official Windows 10 IoT Enterprise LTSC 2021 edition to get updates till Jan 13, 2032.

Upgrade Windows 10 Home, Pro, etc editions to Windows 10 IoT Enterprise LTSC 2021 while keeping files and apps
Download Windows 10 Enterprise LTSC ISO from here in the same Windows language and architecture.
To check the installed Windows architecture, open Powershell as admin and enter,
Get-WmiObject -Class Win32_OperatingSystem | Format-List OSArchitecture
x64 means 64 Bit, x86 means 32 Bit
To check the installed Windows Language, open Powershell as admin and enter,
dism /english /online /get-intl | find /i "Default system UI language"
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.
Now open the command prompt as admin and enter,
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 take time at this step, otherwise it won't show an option to keep files and apps)
Make sure it says "Keep all files and apps" on the final screen. Then you can continue the process and wait until it is done.
That's all.
Notes
Windows 10 ESU updates
Microsoft announced Extended Security Updates (ESU) where users can buy the ESU subscription to receive Windows updates. These updates will begin to roll out in November 2025.
We will update this post in the future on how you can easily get these updates for free (if you don't want to use LTSC editions).
Windows 11 IoT Enterprise 24H2 / IoT Enterprise LTSC 2024
Many users choose not to use Windows 11 due to hardware limitations, such as a lack of TPM, Secure Boot, or UEFI support. While it is possible to bypass these limitations, doing so is officially unsupported and may lead to issues with future updates.
There is good news.
In 2024, Microsoft released Windows 11 IoT Enterprise 24H2 (GAC) / IoT Enterprise LTSC 2024 (LTSC) which has relaxed hardware requirements. You can officially install these Windows 11 editions without meeting the usual hardware requirements, such as TPM, Secure Boot, and UEFI, while still receiving continued support in the future.
