Intel® Optane™ Memory and Storage Management Extension Driver:

Intel® Optane™ Memory is a high-performance memory technology that works in conjunction with your PC's storage system to accelerate data access and improve overall system responsiveness. It uses Intel's 3D NAND memory and a special type of software (driver and utility) to store frequently accessed data, providing faster access to that data, which helps improve the speed and performance of your system, particularly in cases where your primary storage is a slower hard drive (HDD).

The Intel® Optane™ Memory and Storage Management Extension is a Windows driver that enables the proper functioning of Optane memory and integrates with Intel® Rapid Storage Technology (RST). This extension is responsible for managing the acceleration of your system's storage, ensuring that data is cached correctly and improving overall performance for tasks like booting up, launching applications, and loading files.
