What mean OEM SLP?

OEM SLP stands for Original Equipment Manufacturer System Locked Preinstallation. It refers to a version of the Windows operating system that is pre-installed by the OEM on a computer or device, often with a specific key tied to that hardware. This version is typically locked to the device it was installed on, meaning it cannot be transferred to another machine. OEM SLP versions are designed to streamline the installation process for manufacturers and ensure that users receive a genuine copy of Windows.
