Known issues with ESET products and Windows 10


  • Resolve common issues after upgrading to Windows 10 with ESET installed


The latest versions of ESET home and business products can be used with Windows 10. If you currently use ESET products and are planning to upgrade to Windows 10 from an earlier version of Windows, we recommend that you upgrade to the latest available version of your ESET product before installing Windows 10.

See our Knowledgebase article for detailed information about upgrading to Windows 10 with specific ESET product versions installed.

ESET consumer products version 9 and later and business products version 5 and later are compatible with the latest Windows 10 version. 

Information for those who plan to upgrade or have already upgraded to the latest Windows 10 version:

Microsoft has changed their rules for detection of compatible applications in Windows 10. As a result, ESET product versions considered compatible in the past may be disabled after upgrading to Windows 10.

Affected versions of ESET that will be automatically upgraded:

Consumer versions 

ESET NOD32 Antivirus 
(all languages)


ESET Smart Security 
(all languages)


Business versions 

ESET Endpoint Antivirus 
(all languages)


ESET Endpoint Security 
(all languages)


If you have already upgraded to Windows 10 with an affected version of your ESET product installed, you will be prompted to upgrade to the latest version of your ESET product. Full functionality will be restored after installing the latest version.

Known Issues with Windows 32-bit systems

After upgrading to Windows 10 version 1803 (April Update), some users running Windows 32-bit systems may receive one of the following ESET error messages:

  • Modules fail to load
  • "Antivirus Protection is Nonfunctional"


I. ESET Antivirus and Antispyware scanner module 1539.1 has been released. This module disables the "Protected service" on Windows 10 1803 (RS4) 32-bit systems as a temporary workaround for the failed modules issue.

For affected users, Protected services will be re-enabled by an ESET module update when Microsoft and ESET implement a permanent solution.

II. Upgrade to a 64-bit version of Windows.

We are working with Microsoft to permanently resolve this issue and will continue to update this content as additional information is available.

Known Issues with ESET Endpoint Security and ESET Endpoint Antivirus

  1. Incorrect priority of 'ESET: Computer shutdown after scan' window

    If you have enabled shutdown after running a Computer scan and you are running an application in the maximized mode (for example, Internet Explorer), the window is not displayed on the top. In this case, you will not be notified of the running application during the shutdown process.
  2. ecmd.exe is not recognized as a trusted app

    To run the ecmd.exe command line utility, click Yes in the Action Center dialog window.

  3. Issues with Windows Updates in Windows 10

    In Windows 10, Microsoft has introduced a revised Windows Update procedure. This new procedure involves more granular application of updates for individual components, and can cause your ESET program to indicate that updates are required after required updates have already been installed.
