Starting with Windows 10 and Windows Server , the operating system automatically reduces the size of the WinSxS folder by using methods similar to the ones described in this topic. Windows also uses internal processes to reduce the size of the WinSxS folder, such as uninstalling and deleting packages with components that have been replaced by other components with newer versions.

Previous versions of some components are kept on the system for a period of time, allowing you to rollback if necessary. After a period of time, these older components are automatically removed from the installation. You can also reduce the size of a Windows image using some of the same techniques, as discussed in Reduce the Size of the Component Store in an Offline Windows Image.

Deleting files from the WinSxS folder or deleting the entire WinSxS folder may severely damage your system so that your PC might not boot and make it impossible to update. In Windows 10 and Windows Server , you have a number of ways to start the cleanup of the component store, which use a combination of package deletion and component compression to clean up the WinSxS folder:.

The StartComponentCleanup task automatically cleans up components when the system isn't in use. When run automatically, the task will wait at least 30 days after an updated component has been installed before uninstalling the previous versions of the component.

If you choose to run this task, the task will have a 1 hour timeout and may not completely clean up all files.
