Hi @Jamal Talibi
Windows 10 Enterprise LTSC Evaluation is a version of Windows 10 for enterprise users that provides a longer support cycle and fewer feature updates to ensure system stability and security. However, this version also has some limitations, such as:
You can only use it for 90 days, after which the system will automatically shut down every hour and prompt you to activate or upgrade Windows.
You cannot activate it with a digital license or product key because it is an evaluation version, not a full version.
You can't upgrade to other editions directly from Windows Settings because it's a Long Term Servicing Channel (LTSC ) edition that doesn't support getting feature updates from Windows Update.
Therefore, if you want to continue using Windows 10 Enterprise LTSC after the trial period, you will need to obtain a product key to activate the system.
Hope the information is helpful.
Best Regards,
Hania Lian
