Microsoft is releasing a security update on January 9, 2018 for all supported operating systems versions (Windows 7-10, Windows Server 2008-2016). This update has compatibility issues with the following Kaspersky Lab solutions:
- Kaspersky Endpoint Security 10 for Windows version 10.3.0.6294 (SP2), including Kaspersky Endpoint Security Cloud.
- All supported versions of Kaspersky Small Office Security.
- All supported versions of Kaspersky Anti-Ransomware Tool.
Other Windows based endpoint solutions for business (KSV, KSWS, KESS, KICS) are not affected.
To fix this issue:
- On December 18, 2017 Kaspersky Lab released the fix which is distributed through the database update. Solutions with this update installed will not have compatibility issues with the Microsoft update.
- Microsoft will apply the update only to machines compatible with it. Update will not be installed on a machine unless readiness flag is set in the registry by protection solution or manually by admin. That means currently all versions of our solutions are protected from incompatibility problems (regardless of databases update date).
- The update will not be installed on machines without this compatibility flag even if the device has no antivirus solutions installed. Installation of Kaspersky Lab solutions without a patch on new computers will not lead to compatibility issues.
- On December 28, 2017 Kaspersky Lab released database update that will enable readiness flag. Solutions with this databases update and later will not have compatibility issues and will allow Microsoft update to install.
- Before January 9, 2018, we will release the patch and update the installers on the website and in the Kaspersky Endpoint Security Cloud console so that Kaspersky Lab applications are installed correctly on computers with the January 9 Microsoft Security update installed.
