Project Xodus Brings Native Xbox PC and Game Pass Games to Linux

Project Xodus is an open-source initiative focused on reverse-engineering Xbox PC and Game Pass titles to enable their use on Linux and Mac systems. The project has made significant progress in Microsoft authentication and package decryption, allowing Linux users to download and process Xbox subscription games locally. The team has successfully reverse-engineered Microsoft’s identity services and license verification systems, unlocking encrypted MSIXVC game files and enabling the verification of game licenses and decryption of installation packages on non-Windows operating systems. Xodus serves as a translation bridge for Microsoft’s proprietary ecosystem services, providing custom proxy libraries for games to function as if they are running in a native Windows environment. It specifically targets modern games built on Microsoft’s GDK framework, excluding older titles using the Universal Windows Platform and those dependent on kernel-level anti-cheat mechanisms. The project aims to improve access to Xbox Game Pass on devices like the Steam Deck by facilitating direct local hardware execution, reducing reliance on cloud streaming and enhancing portable gaming experiences. Community feedback has been positive, with developers actively sharing updates and engaging with inquiries.

ClamAV Setup: Linux Antivirus in 12 Steps [2026]

Malware can threaten Linux systems, which are often mistakenly believed to be immune to viruses. It can be introduced through email attachments, infected files, or compromised plugins, especially when Linux servers interact with Windows clients or handle internet uploads. ClamAV is an open-source antivirus engine maintained by Cisco Talos, designed for scanning mail traffic and file uploads. As of mid-2026, the stable release is ClamAV 1.5.x, with version 1.5.2 being the latest patch. To deploy ClamAV, users need root or sudo access on a compatible Linux machine, at least 2 vCPUs and 2GB of RAM, 5GB of free disk space, and outbound HTTPS access to ClamAV’s signature mirrors. The installation process involves several steps, including configuring freshclam for automatic updates, validating detection with the EICAR test file, and setting up cron jobs for regular scans. ClamAV can also be integrated with mail servers and a SIEM for enhanced security. Common pitfalls in deployment include skipping the initial freshclam run and using clamscan instead of clamdscan for repeated scans. ClamAV is free for commercial use and can also scan Windows systems, although it does not replace comprehensive endpoint protection solutions.

Classic Xbox 360 exclusives may be coming to PC in the future

Recent datamines indicate that Xbox 360 games may soon be available on PC as part of Xbox's backwards compatibility update. Jason Ronald from Xbox announced the introduction of Xbox Backward Compatibility on PC, allowing players to enjoy classic Xbox games, including four currently available titles: BLiNX: The Time Sweeper, Conker: Live and Reloaded, Crimson Skies: High Road to Revenge, and Fuzion Frenzy. The datamine findings suggest that Xbox 360 titles could be included in this initiative, with an emulator running within another emulator to facilitate compatibility. The Xbox One translation layer software, XWine1, has already successfully run several Xbox 360 games on PC. Although Microsoft has not officially confirmed the inclusion of Xbox 360 games for PC, the release of original Xbox titles may signal a broader initiative to bring more classic games to the platform.

Enable BitLocker on Windows 11: 11 Steps, 45 Min [2026]

A stolen laptop can lead to a significant data breach, particularly when taken from public places. Windows 11 has introduced BitLocker, a full-disk encryption feature that became mandatory for Australian businesses in 2026. The Office of the Australian Information Commissioner reported 766 notifiable data breaches in the latter half of 2024, with unauthorized access to devices being a major cause. Full-disk encryption is crucial for compliance with the Essential Eight framework, which mandates data protection on portable devices. BitLocker ensures that data on an encrypted drive becomes unreadable if the drive is removed and connected to another computer. It aligns with the Essential Eight framework, requiring evidence of encryption rather than just claims of protection. There are three types of encryption on Windows 11: Device Encryption, BitLocker Drive Encryption, and File-Level Encryption. BitLocker is available only on Windows 11 Pro and higher editions. To use BitLocker, certain prerequisites must be met, including having Windows 11 Pro or higher, a Trusted Platform Module (TPM) 2.0, UEFI firmware with Secure Boot enabled, and local administrator rights. The process to enable BitLocker involves confirming the edition, checking TPM status, enabling BitLocker through Windows Settings or PowerShell, and backing up the recovery key. Organizations can deploy BitLocker fleet-wide using Microsoft Intune, and additional security measures like TPM+PIN can be implemented for pre-boot authentication. Common pitfalls during BitLocker rollout include skipping recovery key backup and assuming that Home edition machines are covered. Troubleshooting common BitLocker issues involves identifying symptoms and applying appropriate fixes. Advanced tips for enhancing security include suspending BitLocker before maintenance and auditing compliance at the fleet level. BitLocker is integral to protecting data on portable devices, and compliance documentation is essential for proving that every device has an active recovery key.

Steam Machine compatibility checks are here, though not every game on the store enjoys a rating

Steam users can now check a game's compatibility with Steam Machine and SteamOS directly from the store page. This feature was introduced after the Steam Machine's June release. Players can click 'learn more' next to the Steam Deck compatibility rating for an overview of compatibility across Valve's hardware and software. The game Black Myth: Wukong has an 'unknown' compatibility status with the Steam Machine, while it runs successfully on SteamOS. Valve is investigating compatibility for titles like Dragon’s Dogma 2 and Elden Ring Nightreign. Some games, like 007: First Light, can achieve a 'Verified' rating on the Steam Machine. Currently, the Steam store does not allow filtering by Steam Machine or SteamOS compatibility, but this feature is expected soon.
