Windows 10: Microsoft corrects graphics problems after faulty updates

After releasing the security updates KB5001330 and KB5001337 for Windows 10 from 13. April 2021 had some users of the operating system of different unavoidable "Side effects" reported. Especially in the gaming sector, the updates caused performance losses with jerking graphics to bluescreens and other errors. On some computers, the problems had already passed since Marz, as long as the (also faulty) preview update KB5000842 for Windows 10 V2004 / 20h2 of 29. Marz had been installed.

After the graphics card manufacturer nvidia had also recommended the uninstallation of the relevant updates, Microsoft has now reacted. The company confirmed the complications, on the Our Site last week, has reported, confirmed – or at least those in terms of the game area. Over, there was the problems meanwhile with the help of the function "Known IE Rollback" (KIR) have corrected from a distance, so that it should no longer occur on the originally affected systems.

Supporting and limitation by Microsoft

The error support by Microsoft in the status area of Windows 10 Version 2004 / 20h2 took place last Friday, the 23. April. Redmond wrote that a small subgroup of users after installing KB5000842 (Preview Update for Windows 10 V2004 / 20h2 from 29.3.) or later updates – which were meant by the Preview Update KB5001330 and KB5001337 – a lower performance than expected in games reported.

Most users who have been affected by this problem led according to Microsoft Games in full screen mode or in borderless window mode and used two or more monitors. It is noteworthy in this context that both clients with Windows 10 version 2004 and 20h2 and with Windows Server version 2004 / 20h2 are specified as affected.

Graphic problems via known IE rollback eliminated

The Function Known IE Rollback (KIR), from which Microsoft made use in the current case for remote error correction, had only been presented at the beginning of Marz 2021 in a TechCommunity post. Originally, KIR is therefore developed in user mode processes in order to automatically resolve problems occurring at runtime. In the course of the year 2020, the Microsoft developers then have gradually improved improvements in the operating system core and the bootloader to support the Kir function in kernel mode. Known IE Rollback (KIR) is only available from Windows 10 version 2004 for full use, as only there updates are installed so that the previous code of a bug fix can be maintained and reactivated.

With Known IE Rollback (KIR), Microsoft has an instrument on the hand to make malfunctions by bug fixes in Windows 10 clients and the server counterparts specifically to a previous state when a critical regression is discovered. From Microsoft, without active intervention of the user, can be fully totally totled as long as the systems can communicate with the services for Windows Update or Windows Update for Business. The affected Windows 10 clients will then be returned within 24 hours to the state before rolling out the faulty fix. Microsoft writes that a restart of the client can initiate the rollback function under circumstances even before completing this 24 hours.

No KIR in the business environment

But it is important to know that Microsoft Known IE Rollback (KIR) applies to your own information only for problems caused by non-security-relevant correction updates. Specifically, the code for a particular bugfix is deactivated and not the entire update can be accessed or controlled. uninstalled. In addition, the automatic correction mentioned here is available for non-managed Windows 10 systems in the Consumer area for unauthorized Windows 10 systems. This also takes small companies with single systems. In the business environment, where systems with Windows 10 Enterprise are used and the updates are managed for about WSUS, SCCM or Intune, however, special group policies are used.

The Rollback Via KIR apparently does not help in all traps against the current graphics ies, it’s upgrading in some useful feedback messages. What the (certainly multilayer) reason for this fact is in detail remains open; Requests and discussions in the forum are welcome.
