Call of Duty: WWII Returns to Microsoft Store After Security Fix

After more than a month of absence, Call of Duty: WWII has officially reappeared in the Microsoft Store and PC Game Pass. The 2017 Sledgehammer Games title was pulled from the storefront just days after its Game Pass debut when a serious security issue was discovered on Windows PCs.

In late June, WWII launched on Game Pass. Within days, reports started to surface from PC players. Many said their computers were being taken over while the game was running.

The problem turned out to be a Remote Code Execution (RCE) exploit. In simple terms, this allowed hackers to run programs on another player’s PC without permission. Some clips on social media showed desktops opening strange windows and even malware being installed.

Because of the risk, Activision and Microsoft pulled the game’s Windows version from the Microsoft Store. Xbox players were safe, since the console uses a secure, custom Windows kernel. Versions on Steam and Battle.net also remained unaffected.

Now, the game is live again. Activision says the exploit has been fixed, though the company hasn’t gone into detail about the patch. For most players, the main thing is simple: WWII is once again playable through Game Pass.

The pause also shows the challenge of bringing older Call of Duty titles to the Microsoft Store. Many were first built for Battle.net, and moving them across requires extra work. Sometimes that process can introduce new problems, as we saw here.

This wasn’t just a small bug. RCE vulnerabilities are among the most dangerous in gaming because they give attackers deep control of a system. Even though it only affected one store version, the risk was high enough to warrant a full removal.

For Microsoft and Activision, the return is a relief. Game Pass now includes one of the most requested Call of Duty campaigns. For players, it’s a reminder to keep automatic updates on and stay alert when older titles make their way onto new platforms.
