RTX64 Support for Windows 11 Updates

Like Windows 10, Microsoft considers Windows 11 to be a service.

Windows 11 has two types of updates:

Feature updates add new features to Windows 11. These updates occur once per year and can be postponed for up to 365 days.
Quality updates deliver both security and non-security fixes for all supported Feature updates. Quality updates are released monthly and typically have names like KB12345. Quality updates are cumulative and can be postponed for up to 30 days.

To ensure the success of our customers, IntervalZero tests each new Windows 11 update in-house on supported RTX64 product versions. See below for the results.

RTX64 Runtime is incompatible with the Windows Memory integrity security feature

Windows updates might enable the Windows Memory integrity security feature, which is not compatible with RTX64 Runtime. This feature must be turned off to avoid issues with RTX64 Runtime. After Windows updates are applied, you can check the status of the Memory integrity feature — and turn it off if it’s enabled — in the Windows Security app under Device security / Core isolation / Core isolation details.

RTX64 does not currently support Windows 11 IoT Enterprise LTSC 2024 or the Windows 11 24H2 Feature Update. Support will be added in an update to RTX64 4.5, which is planned for release in December. If you have any questions, please contact Sales or Product Management.

Windows 11 Support

The tables below list the current RTX64 compatibility testing status for each Windows 11 update version.

There are three test status types:

Active – IntervalZero actively tests the update as new revisions are released (typically on a monthly basis). See Windows 11 Updates Actively Tested below for a listing of the KBs we tested.
Ended – The update has reached its End of service and is no longer actively updated by Microsoft. IntervalZero has stopped testing the update, since Microsoft will not be introducing breaking changes.
Not supported – The update is not supported by any RTX64 product.

All dates are listed in ISO 8601 format: YYYY-MM-DD

About Windows 10 Updates

For a listing of RTX64 compatibility testing status for Windows 10 update versions, visit RTX64 Support for Windows 10 Updates.

About Windows 7 Updates

We do not proactively test Windows 7 (64-bit) monthly updates since such updates can be disabled. As far as we are aware, there are no known issues since the initial Meltdown-Spectre issue which was fixed in Update 1 for RTX64 3.3. If you encounter an issue with a Windows 7 (64-bit) monthly update, please notify IntervalZero Support so that the issue can be investigated.
