Microsoft has confirmed a controversial change in its latest Windows 11 updates, enabling by default a system service that has long been criticised for consuming excessive resources.
The AppX Deployment Service (Appxsvc), which manages Microsoft Store apps and updates, has been switched from “Manual (Triggered)” to “Automatic” startup type in the December 2025 non-security cumulative update (KB5072033).
This means the service will now run continuously in the background from system boot, rather than activating only when required.
The change was noted in updated release notes for Windows 11 versions 25H2 and 24H2, as well as Server 2025. Microsoft explained the move was intended “to improve reliability in some isolated scenarios.”
However, users have frequently reported that Appxsvc can cause high CPU usage, memory consumption, and disk activity, raising concerns that the adjustment could negatively impact performance, particularly on lower-spec machines.
Previously, the service would only start when a Store app was launched or updated, minimising its impact on system resources.
Now, with the automatic setting, the process will remain active at all times. Microsoft has cautioned that disabling Appxsvc could prevent Store apps and updates from functioning properly.
The timing of the change appears linked to Microsoft’s broader strategy of integrating Store updates into the Windows Update channel.
By keeping Appxsvc permanently active, the company ensures Store-related processes are always ready to receive updates.
While the update also introduced a major performance boost for Server 2025 systems reportedly improving storage speeds by up to 80 percent the decision to enable Appxsvc by default has sparked debate among users.
Online forums have already seen renewed complaints about the service’s resource demands, with some warning that older or budget PCs could struggle under the additional load.
For now, Microsoft maintains that the change will enhance reliability, but the real-world impact on everyday users remains to be seen.
