Windows Server 2012 RDS (Remote Desktop Services) with 50 user connections is a version of Windows Server specifically designed to support up to 50 simultaneous remote user connections. This makes it suitable for businesses or organizations that need to provide remote access to applications, desktops, or remote desktop sessions for a larger number of users. However, it's important to note that Windows Server 2012 R2 is an improved version of Windows Server 2012 and is recommended for better performance, security, and features. Mainstream support for Windows Server 2012 R2 ended on October 9, 2018, and its extended support is set to end on October 10, 2023. Given the end-of-life status of these versions, it's advisable to consider upgrading to a more recent and supported version of Windows Server, such as Windows Server 2019 or Windows Server 2022, to ensure security and access to the latest enhancements and features.
