About this tag
The appxsvc tag covers discussions about the AppX Deployment Service (AppXSVC) on Windows 11 and Server 2025, particularly following the December 2025 cumulative update KB5072033. This update changed AppXSVC from a trigger-start to an automatic startup type, leading to reported slowdowns, longer boot times, and increased background resource usage. Users and IT administrators share mitigation steps, such as reverting the startup type, and discuss performance tradeoffs. The tag also includes related issues with Delivery Optimization (DoSvc) memory growth, which some users link to the AppXSVC change. Content focuses on troubleshooting, performance impacts, and practical guidance for managing these service behaviors.
