wsappx

The wsappx service is a core Windows component responsible for managing the installation, update, and removal of Microsoft Store apps. On WindowsForum.com, users frequently report high CPU usage and disk space issues related to wsappx, particularly after major updates like Windows 10 version 1803. Common problems include the service consuming excessive CPU resources and the temp folder filling with appxdeployment server.evtx log files, which can quickly occupy tens of gigabytes. These issues often persist even after disabling Store updates. Discussions focus on troubleshooting wsappx performance, identifying causes such as update failures or corrupted app packages, and finding effective solutions to reduce resource usage and prevent disk space exhaustion.
