Introduction

Ubisoft has recently addressed significant compatibility issues affecting its flagship Assassin’s Creed titles on systems running Windows 11 version 24H2. This development comes after numerous reports from players experiencing crashes, freezes, and performance degradation following the operating system's latest feature update.

Background

In November 2024, Microsoft rolled out the Windows 11 24H2 update, introducing various enhancements and new features. However, shortly after its release, gamers began reporting problems with several Ubisoft titles, notably Assassin’s Creed Valhalla, Assassin’s Creed Origins, and Assassin’s Creed Odyssey.

Ubisoft's Response

Acknowledging the widespread issues, Ubisoft initiated investigations and, by mid-January 2025, released patches aimed at resolving these compatibility problems. The updates, approximately 230 MB for Assassin’s Creed Origins (version 1.62) and 500 MB for Assassin’s Creed Valhalla (version 1.7.0), were designed to fix the crashes and freezes that players were experiencing.

Microsoft's Involvement

In response to the reported issues, Microsoft implemented a compatibility hold, preventing devices with the affected Ubisoft games from receiving the Windows 11 24H2 update. This measure aimed to safeguard users from the known problems until a resolution was available. Following the deployment of Ubisoft's patches, Microsoft lifted the upgrade blocks, allowing users to update their systems without encountering the previous disruptions. (bleepingcomputer.com)

Ubisoft's patches addressed these conflicts by updating game files to ensure compatibility with the new OS version. Additionally, Microsoft resolved related issues, such as problems with Auto HDR causing games to stop responding or display incorrect colors, through subsequent updates. (learn.microsoft.com)
