api-ms-win-core-memory-l1-1-6.dll is a system file in Windows that acts as an "API Set" to manage advanced memory operations
. It is primarily a redirection layer that allows applications to access memory functions without needing to know exactly where they are stored in the system's core files (like kernelbase.dll Key Features & Functions
This specific version (l1-1-6) introduced and manages several critical memory management functions: Virtual Memory Allocation : Includes functions like VirtualAlloc2 VirtualAlloc2FromApp
, which allow developers to reserve, commit, or change the state of memory regions with extended parameters. File Mapping : Provides MapViewOfFile3 MapViewOfFile3FromApp
, enabling applications to map a portion of a file into their memory space for high-speed access. Memory Resource Notifications
: Allows programs to query the state of system memory—such as low or high memory alerts—so they can scale their usage accordingly. Modern App Support api-ms-win-core-memory-l1-1-6.dll
: Many of the "FromApp" functions in this DLL are specifically designed to allow Universal Windows Platform (UWP) apps to perform memory tasks securely. Microsoft Learn Common Issues
