Unable to Extend C Drive on Windows Server 2016

If you have been using the Windows Server 2016 for a while now, you may have noticed the unreasonable space that it allocates to the system partition. Windows Server 2016 and its newer version up to 2019, no doubt, features amazing updates and unique options but these system utilities start to consume significant GBS after few updates. Additionally, the ability to resize or extend the c-drive is not available in the Windows Server 2016 at the time of installation. Low disk space can cause your computer to slow down, cause errors while performing operations, and may accumulate it with viruses. Therefore, it is necessary to find ways to extend c-drive on windows server 2016.

Before getting to the actual solution, you can also use the following built-in utilities to free up space in the c-drive.

  • Disk cleanup
  • Deleting unnecessary system and application programs
  • Deleting temporary files

If the following solutions do not work for you and the disk space problem remains, follow the complete article below.
