Microsoft released Patch Tuesday updates for the month of December 2025 last week under KB5072033 for Windows 11 25H2 and 24H2, and Server 2025 and today Neowin noticed that the tech giant updated the release notes for the C.U. (cumulative update) to include this system process change. It writes:
"December 15, 2025 Update: This feature is included in the December 2025 non-security update (KB5072033).
- [System Components] The AppX Deployment Service (Appxsvc) has moved to Automatic startup type to improve reliability in some isolated scenarios."
A quick Google search for the Appxsvc service leads to various forum posts and results online where users are seen complaining about this system process. This ranges from issues related to high CPU usage, memory usage, or disk impacts. Hence, the process could be a major potential resource and performance hog depending on how it could affect a user's PC.
By default the Startup type for the service was previously set to "Manual(Triggered)" so that it could be launched on demand when a Store app needed to be accessed; but now Microsoft is making it "Automatic", which means low-spec and less powerful PCs running the newer versions of Windows 11 could be in for a bad surprise as the process will continue running in the background as soon as the system boots up.
