RTX64 Support for Windows 10 Updates

Unlike previous Microsoft Operating Systems, Microsoft considers Windows 10 to be a service. Microsoft has modified its Windows 10 update practices and has restricted a user’s ability to prevent updates.

Windows 10 has two types of updates:

  • Feature updates add new features to Windows 10. These updates occur twice per year, typically around March and September, and typically have names like Fall Creators. Feature updates 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 10 update in-house on supported RTX64 product versions. See below for the results.

Windows 11 support

Support for Windows 11 in RTX64 4.2 was confirmed in February 2022. Full compatibility requires RTX64 4.2.1 or the Tools Update for RTX64 4.2, available from the Customer Center. For a listing of RTX64 compatibility testing with Windows 11 update versions, see RTX64 Support for Windows 11 Updates.

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.

 


Windows 10 Support

The tables below list the current RTX64 compatibility testing status for each Windows 10 update version by servicing option: Semi-Annual Channel and Enterprise and IoT Enterprise LTSB/LTSC editions.

There are three test status types:

  • Active – IntervalZero actively tests the update as new revisions are released (typically on a monthly basis). See Windows 10 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. See Windows 10 Updates No Longer Tested below for a listing of the KBs we tested.
  • Not supported – The update is not supported by any RTX64 product.

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.
