Microsoft has confirmed that it will enable a Windows system service by default. This service is known to cause performance issues on users' computers from time to time, as it can consume CPU and memory blocks.

Microsoft released the December 2025 Patch Tuesday update last week with KB5072033 for Windows 11 25H2, 24H2, and Server 2025 , and updated the release notes for the CU (cumulative update) to include this specific change :

“December 15, 2025 Update: This feature is included in the update and is not part of the December 2025 security update (KB5072033).

[System Components] The AppX service (Appxsvc) has been moved to autostart type to improve reliability in some isolated scenarios.”

A quick Google search for the Appxsvc service leads to various posts and results online where users seem to be complaining about issues related to high CPU usage, memory usage, or disk impact. So the process could be a significant factor in reducing resources and performance.

By default, the startup type for the service was set to “Manual (Enabled),” so it could start on demand when a Store app needs to be accessed. But now Microsoft will make it “Automatic,” which means that low-end and less powerful computers running newer versions of Windows 11 could be in for some unpleasant surprises, as the process will continue to run in the background once the system boots.

For those wondering what the Appxsvc service is, this process essentially handles Microsoft Store apps and updates. If forcibly disabled, Microsoft warns that this could cause problems.

Why is Microsoft making the change?

The company recently revealed that it will soon distribute Microsoft Store updates via Windows Update, so all Store-related changes should always be enabled by default.
