With the low disk space problems on Windows Server 2003,2008, 2012 and so on, extending disk partition has become one of the biggest query related to SBS. The main reasons why Windows SBS faces the low disk space problems is its extra tools, features, and updates. As the SBS starts to update certain features after a few weeks of installation, the size of the operating system also starts to grow – thus occupying more storage space. To free up disk space, it is recommended to extend volume by resizing c-drive.
