How to check what Version & Build of Windows you are running (source:http://www.howtogeek.com/236195/how-to-find-out-which-build-and-version-of-windows-10-you-have):



Use the Settings App


The new Settings application also offers this information in a user-friendly form. To launch it, click or tap the Start button and select Settings.



Navigate to System > About and scroll down. You’ll see the “Version” and “Build” numbers here.

  • Edition: The “Edition” line tells you which edition of Windows 10 you’re using — Windows 10 Home, Professional, Enterprise, or Education. 

  • Build Number: Look at the “Version” and “OS Build” lines. If you have the original version of Windows 10, you’ll just see “OS Build 10240”. This was the initial release of Windows 10. If you have the “November Update” version of Windows 10 — Windows 10’s first big update— you’ll see a new version number scheme here. It’ll say “Version 1511 (OS Build 10576.29)”.
    The “1511” is the key. This number identifies that you’re using the build of Windows 10 released in November (the 11th month) of 2015. If Microsoft were to release a build of Windows 10 in April (the 4th month) of 2016, its version number would be “Version 1604”.

  • 64-bit or 32-bit: The “System type” line tells you whether you’re using the 32-bit version of Windows 10 or the 64-bit version. It also tells you whether your PC is compatible with the 64-bit version or not.
    For example, “64-bit operating system, x64-based processor” indicates you’re using a 64-bit version of Windows 10 on a 64-bit processor. “32-bit operating system, x64-based processor” indicates you’re using a 32-bit version of Windows 10, but you could install the 64-bit version on your hardware if you preferred.


If no version number is presented it means that you are only running a Windows 10 Insider Preview Build.

Windows 10 Insider Preview Program builds are not supported by ESET Smart Security and ESET NOD32 Antivirus version 9 - 

This means that you will either need to upgrade your Windows build or if you have purchased your ESET license within the last 30 days you may be entitled to a refund. 


Please advise the Build & Version number and we will continue the support.
