Windows 10: how do I know if a copy of Windows 10 Enterprise LTSC has been previously activated or if...

I recently purchased a copy of Windows 10 Enterprise loT LSTC key and they sent the wrong product key and will not take a return. How do I find out if the key is actually legit and if it has already been activated? The company I purchased it from will not take it back because they claim it has already been activated but I haven't even installed it much less activated it. This company is a little on the questionable side so it is very difficult for me to deal with them and I paid $200 for the key!! I was trying to keep Windows 10 for a few more years and I heard the Enterprise LSTC version

Windows 10 Enterprise to Windows 10 LTSC - MAK Activation

Hello,

Our software group is investigating changing our Window 10 Enterprise laptops to Windows 10 LTSC. We are considering this change because of the remote location of the laptops and the increasing issues with upgrading Windows in order to receive service/quality/security
updates. These laptops are not connected to the Internet at any time. We activate by using another computer connected to the Internet using the VAMT tool (IID and CID files). We have a MAK license with the Windows 10 Enterprise version. When I load the LTSC
over the Window 10 Enterprise 1809, the Product Keys are not valid. We thought that the same Product Keys would work with LTSC. Is this not the case, or is there another step that needs to take place?

Thanks in advance,

MJ

 

[Urgent] Activate Windows 10 Enterprise 2019 LTSC OS

Hi,

I have existing virtual machines loading Windows 10 Enterprise 2019 LTSC created from ISO file and I need to activate them.

I was told that I have to buy both Windows 10 Pro licenses and upgraded licenses to Enterprise LTSC. I was also told that I have to rebuild my VMs with Win 10 Pro first and activate, then install Win 10 Enterprise LTSC and activate again, after all software and libraries have been installed and configured.

So my questions is how to correctly and easily license existing Windows 10 Enterprise 2019 LTSC OS?

 

How to upgrade Windows 10 Enterprise version 1809 LTSC to the latest version of Enterprise LTSC

Hi,

I wanted to upgrade from Windows 10 Enterprise LTSC version 1809 to the latest version of Enterprise.

Tried to upgrade by downloading the latest copy of enterprise LTSC from MS. Mounted and ran the setup but it says you can't keep anything.

My question is how to keep apps & data while upgrading enterprise LTSC to the latest version. Is there any other way to upgrade Windows 10 enterprise LTSC to the latest version?
