ERROR_STATE_COMPOSITE_SETTING_VALUE_SIZE_LIMIT_EXCEEDED - 15815 (0x3DC7)
The size of the state manager composite setting value has exceeded the limit.
Updated: Feb 21, 2026
Technical Meaning
This error code indicates that the size of a composite setting value managed by the state manager has exceeded the predefined limit. The state manager is responsible for managing and persisting application settings across system restarts.
Error Details
The state manager enforces limits on the size of composite settings to ensure efficient storage and retrieval operations. When an attempt is made to set a composite setting value that exceeds this limit, the error ERROR_STATE_COMPOSITE_SETTING_VALUE_SIZE_LIMIT_EXCEEDED (15815) is returned.
Usage Context
This error typically occurs when attempting to modify or create a composite setting with a value that surpasses the maximum allowed size. Composite settings are used for storing complex data structures, such as arrays or nested objects, which can be larger than simple scalar values like strings or integers.
Developer Interpretation
Developers should ensure that any composite setting values they intend to set do not exceed the specified limit. This is particularly important when dealing with large data structures or when integrating third-party libraries that may generate such settings.
Related Errors
ERROR_STATE_SETTING_VALUE_SIZE_LIMIT_EXCEEDED(15809) - Indicates a similar issue but for individual settings rather than composite ones.ERROR_STATE_SETTING_NOT_FOUND(2746) - Occurs when attempting to access a setting that does not exist, which might be unrelated to the size limit issue.
FAQ
Q: What is a composite setting?
A: A composite setting in Windows refers to a complex data structure stored by the state manager. It can contain multiple values or nested objects and is used for storing more intricate application configurations.
Q: How do I check if my settings are within size limits?
A: Review the documentation provided with your application or library to understand the maximum allowed sizes for composite settings. You may also use debugging tools to monitor setting operations and their outcomes.
Summary
The ERROR_STATE_COMPOSITE_SETTING_VALUE_SIZE_LIMIT_EXCEEDED error code is a specific technical issue related to resource limits in Windows state management. Developers should ensure that any composite setting values they intend to set do not exceed the predefined size limit to avoid this error.
