Microsoft releases KB5007262 to fix installer-related app issues in Windows 11

Windows 11 magnifying glass

Just yesterday we wrote about an issue with the Microsoft Installer which is causing problems with various apps.

The MSI issue affects a wide range of versions of Windows and Windows Server, and in the case of Windows 11 Microsoft has been fast to act. The company has issued KB5007262 as a cumulative update to fix the recently acknowledged problem with, among other software titles, Kaspersky Endpoint Security for Windows .

Kaspersky warns users of its Endpoint Security app: "After the installation of a Windows update Kaspersky Endpoint Security for Windows keeps functioning correctly and the security of the system remains intact. However errors may occur at attempts to upgrade the application, install a private patch or change the scope of the application components".

For the time being, Microsoft's KB5007262 update is only available to Windows Insiders who are participating in the Beta or Release Preview channels. Assuming there are no major issues with the patch, it will make its way to non-Insider builds of Windows 11, but at the moment it is hard to say just when this will be.

Microsoft says of the update:

Hello Windows Insiders, today we’re releasing Windows 11 Build 22000.348 (KB5007262)to Windows Insiders in the Beta and Release Preview Channels.

This update includes all the improvements previously noted here plus this additional fix:

- We fixed a known issue that might prevent apps, such as Kaspersky apps, from opening after you attempt to repair or update the apps using the Microsoft Installer (MSI).

The Windows Insider Program Team

For non-Insiders and anyone running an older version of Windows the advice from Kaspersky is to "to temporarily refrain from installing the Windows updates" known to be problematic. The company shares a list of updates to be aware of:
