Microsoft’s change to Appxsvc may slow some Windows 11 PCs

Microsoft is modifying core system settings for Windows 11 versions 24H2 and 25H2 by enabling the AppX Deployment Service (Appxsvc) to launch automatically upon boot-up, transitioning from a manual trigger system. This change was confirmed in the December 2025 "Patch Tuesday" update (KB5072033) for both Windows 11 and Windows Server 2025. The Appxsvc will now remain active in the background from the moment the computer powers on, regardless of Microsoft Store access, to enhance system stability and minimize app installation failures or update glitches. Microsoft warns against manually reverting this setting, as it could lead to malfunctions in Store apps and essential services. Analysts suggest this move aligns with a strategy for updating Microsoft Store apps directly through Windows Update.

This hidden Windows 11 setting might be quietly draining your RAM — here’s a quick fix

Microsoft has concluded support for Windows 10 and introduced Windows 11 25H2, which has a feature called Delivery Optimization that is reportedly consuming excessive system memory, leading to sluggish performance on some PCs. A user on Reddit noted that Delivery Optimization may have a memory leak, as its memory consumption is disproportionately high even when not actively needed. This feature is designed to expedite the download of Windows updates and applications by sharing downloaded packages with other devices. However, a recent update has caused the AppX Deployment Service to activate automatically at startup, increasing CPU, memory, and disk usage. Users can disable Delivery Optimization to alleviate memory strain, though this may result in slower download speeds for updates. The steps to disable it involve accessing Windows Update in Settings, navigating to Delivery Optimization, and toggling off the option to allow downloads from other devices.

Microsoft now runs resource-hogging AppX Deployment Service at Windows 11 startup

Microsoft released a cumulative update for Windows 11, designated as KB5072033, which included a change to the AppX Deployment Service (Appxsvc), setting it to automatic startup to improve reliability. This change was not initially mentioned in the release notes but was later added, noting that it aims to enhance reliability in isolated scenarios. Users have expressed concerns about high resource consumption linked to this service, particularly on lower-spec machines. The update also introduced a standardized format for Windows Update titles to improve readability, announced that there will be no non-security preview update in the latter half of December 2025, and noted that Secure Boot certificates for most Windows devices will expire starting in June 2026. Additionally, Windows Updates will not include updates for Microsoft Store applications, with enterprise users advised to consult Configuration Manager for updates.
