What is Windows Server?
Windows Server is a group of Microsoft operating systems (OSes) that utilize highly powerful hardware. Windows Server was first released in April 2003. It is frequently installed on highly trafficked servers, which provide as the backbone of the vast majority of IT enterprises, programs, and services. The server controls operations related to administrative groups on a network. It collects data from network-connected devices and organizes, stores, transmits, and receives it.
Versions of Windows Server
Windows Server is the industry standard for networking. During the past 16 years, Microsoft has released a major version of Windows Server every four years and a minor version every two years. The minor versions are signaled by the suffix R2. The Windows operating system is regularly updated with new features to satisfy the needs of contemporary consumers. The updates and modifications made to the server must be understood by the administrator.
List of every major and minor Windows Server release from Microsoft:

This edition's networking features supported the development of live server pages and supported XMP. This edition also generated tailored versions for server environments with the help of its Advanced Server and Datacenter editions.
- Windows Server 2003 - This version of Windows was developed by Microsoft as the founding member of the NT family of operating systems. With the release of Windows Server 2003, there was a discernible difference. The purpose of Windows Server 2003 was to reduce the number of times the system had to reboot. Updates could be installed without the need to restart the machine. Another feature of Windows Server 2003 that allowed IT firms to customize operating systems for certain purposes like DNS servers was the ability to create server roles. Among the choices were the Windows Server 2003 Standard, Advanced, and Datacenter editions.
- Windows Server 2008 - This server edition was the third iteration of the Windows Server operating system. It introduced the Windows Server operating system, which altered Active Directory as well as the network services and software support components of the OS (AD). One of the key advancements was the Microsoft Hyper-V technology. Because of the ability to create virtual machines (VMs), Windows users could more effectively compete in the market. This release also introduced new administration tools called Event Viewer and Server Manager to give administrators more control over important server activities.
- Windows Server 2008 R2 - Windows Server 2008 R2, an improved version of 2008, was launched in 2009. The significant modifications present in this edition were brought about by the changeover from Windows Vista to being based on Windows 7. This revision included a 64-bit environment conversion as well as further technical updates on auxiliary services. This version improved group policy execution, added new services, and made more AD modifications. Also, it increased server connectivity for users in remote locations thanks to BranchCache and DirectAccess.
- Windows Server 2012 - The current version of the Windows Server operating system is version six. This version, in contrast to its predecessor, has four editions: Foundation, Essentials, Standard, and Datacenter. These editions have a number of enhanced features, such as an IP address management role, a new version of Windows Task Management, an updated Hyper-V, a version of PowerShell, and Server Core. Microsoft enhanced Windows Server 2012 and labeled the upgraded version as Cloud OS in order to increase its competitiveness in the cloud. The enhanced capabilities made it simple for users to combine the Hyper-V architecture with other cutting-edge cloud technologies.
- Windows Server 2012 R2 - With Windows Server 2012 R2, an improved version of Windows 2012, was made available. It was released in 2013 with a number of changes and improvements to Windows 12's functionality to support the integration of cloud services. Among these changes were rewrites of security protocols and network services. Another improvement that will enhance network configuration management is the inclusion of PowerShell and Desired State Configuration systems. Another improvement improved file sharing, increased the capacity of the storage system, and improved distributed file replication.
- Windows Server 2016 - Windows Server 2016 is the name of the seventh iteration of the Windows Server operating system. It was developed concurrently with Windows 10 and served as Windows Server 2012's Windows 8-based replacement. This version added a brand-new server named Nano Server. For security reasons, this server had been shrunk and given a limited interface. This edition also included the introduction of Network Controller, which enables administrators to control both physical and virtual network devices from a single location. Moreover, the VM system was enhanced in this edition to support Hyper-V encryption and the utilization of containers, as well as to streamline Docker interaction. Windows Server 2016 comes in two editions: Standard and Datacenter.
- Windows Server 2019 - Windows Server 2019 is the most widely used version of Windows Server. It was released in October 2018 and had a wide range of capabilities to meet evolving networking requirements, including the following:
- Windows Admin Center - To consolidate server management, the Windows Admin Center was created. Additionally, it offers a range of tools that IT professionals may use regularly for tasks like managing services running across several servers, performance monitoring, and configuration management.
- Hyper Converged Infrastructure (HCI) - Microsoft switched to virtualization after integrating Hyper-V in Windows Server 2008. Better HCI features built into VMs in the most current version of Windows enable network managers to manage virtualized services.
- Microsoft Defender Advanced Threat Protection - Cybersecurity is a major problem for modern businesses, particularly in light of advanced persistent threats. When an attacker attempts to access a network, antivirus software can help prevent attacks like spear phishing, social media profiling, and whaling. This provides state-of-the-art threat protection against fresh cyberattacks. Microsoft introduced Microsoft Defender ATP together with Windows Server 2019. It automatically investigates attacks, maintains track of user activity, prohibits unauthorized changes, and keeps an eye out for suspicious behaviour. Alternatives for corrective action are also provided.
Most important performance metrics for Windows Server
- CPU utilization - Regular CPU monitoring can be crucial for determining CPU load and addressing performance concerns. CPU utilization and monitoring statistics assist in finding outages and other issues in order to better guarantee optimum performance. This helps locating the cause of downtime or CPU spikes simpler.
- Memory utilization - Memory usage monitoring assists in identifying overloaded and underutilized servers as well as unused servers in order to more effectively distribute loads.
- Processor queue length - The size of the processor queue can be determined by the number of threads that each processor handles. These processors can be continuously watched to see if they can effectively handle the amount of threads.
- Disk usage with a capacity plan - Keeping track of how much disk space is being utilized may be necessary for monitoring unforeseen or sudden surges in demand. By keeping an eye on these signs, you may plan ahead, monitor disk usage, and fix the problem before it gets worse and interferes with your server's general performance.
- Top process by CPU and memory - It is essential to look at the CPU consumption to determine how much pressure is being placed on the servers' processor at any one time. In order to address performance concerns, you can utilize this information to upgrade the hardware, add more CPUs, or turn down unnecessary services.
Windows Server Performance Monitoring Best Practices
- Define a baseline - It's a good idea to monitor your server's functioning. When performing a system-level analysis, be sure to carefully evaluate the entire system, not just one metric or component at a time, and to have baselines and measurements established.
- Monitor consistently - Regularly assessing Windows Server performance is crucial. Using monitoring techniques will allow you to keep an eye on crucial elements and their measurements. Monitoring processes can also be automated and scheduled to find problems and server downtime.
- Use tools - Monitoring relevant metrics and taking stock of certain performance metrics might be crucial for spotting problems. Organizations can automate the most challenging activities by implementing programs like patch management, which also keeps servers up to date by checking for failed updates and spotting issues as they appear.
Final Thoughts
Although having similar looks and sharing code, Windows Server and regular Windows are ultimately utilized for very different purposes.
The consumer editions of Windows 10 are designed for maximum usability and don't contain any business-oriented apps. On the other hand, Windows Server doesn't care about appearances. Its objective is to execute a range of services that business users need reliably.
