The Microsoft Windows 10 May 2019 update (also known as 1903) may affect the performance of your ESET product depending on the version of your ESET product.
Version 10.1 and later: If your ESET product is version 10.1, 11, or 12, you do not need to make any changes. Your ESET product is fully compatible with the Windows update.
If you are not sure which ESET product version you are using, learn how to check it here.
As of April 11, 2017 Microsoft Vista customers stopped receiving security updates, hotfixes, etc. from Microsoft. If you are using an ESET product on a computer with Microsoft Vista, Microsoft will begin to enforce their End-Of-Life policy for Vista. Your ESET product will no longer be able to update the Detection engine or any product modules. To stay protected, you will need to upgrade your computer's operating system to a more recent version.
