After four years of designing and development, Microsoft released the server operating system-Windows Server 2012 on September 4, 2012. Windows Server 2012 is not just a mediocre upgrade product.

According to Microsoft marketing statement, “With Windows Server 2012 you can scale to run your most important workloads with robust recovery options. You’ll achieve value quickly with a wide range of cost-effective, high-performance storage options and simplified delivery of multi-tenant IT services. You can build, deploy, operate, and monitor applications on-premises and in the cloud. Empower users with secure access to corporate resources on the devices they choose.”

So we said Windows Server 2012 is great. However, all of its great functions must base on its disk. So disk optimization is important. Now there is a great freeware can perform very well of optimizing partitions on Windows Server 2012 such as partition extending.

The great Server partition management software is named AOMEI Partition Assistant Server Edition. Developed by AOMEI Tech Co., Ltd, it is compatible with Windows Server 2003, 2008 (R2), 2012 (R2), 2016, 2019.

Why do we say it is great? Because it made up for the weakness of Windows Server 2012 built-in disk manager. For example, the built-in one can’t resize and move partition. If we want to extend a partition there must be contiguous space behind it. But We can use AOMEI Partition Assistant Lite resize and move partitions, which is a shortcut to extend partition in Windows server 2012.

Now let’s see the operational details. Install and run it. Our purpose is to extend partition C by getting free space from D drive .
