Extend C Drive in Windows 10 via Disk Management

To extend the C drive in Windows 10 using Disk Management, follow these steps:

1. Press Win + X keys on your keyboard to open the Power User menu and select “Disk Management” from the list.
2. In the Disk Management window, you will see a list of all your drives and their partitions. Locate the C drive partition. It will typically be the one labeled “C:” and have the “Boot” and “System” flags.
3. If there is unallocated space next to the C drive, you can simply right-click on the C drive partition and select “Extend Volume.” If there is no unallocated space, you’ll need to create some by shrinking an existing partition.
   • To shrink a partition, right-click on a partition with available space, and choose “Shrink Volume.” Enter the amount of space to shrink in megabytes.
4. Once you have unallocated space, right-click on the C drive partition and select “Extend Volume.”
5. The “Extend Volume Wizard” will open. Click “Next” to proceed.
6. In the “Select Disk” window, you will see the available space. Ensure that the unallocated space is selected and click “Next.”
7. Click “Finish” to confirm your selections and complete the process.

Disk Management will now extend the C drive using the unallocated space, and the process should be relatively quick.

Please note that if the unallocated space is not next to the C drive, you may need to use third-party partition management tools like EaseUS Partition Master or MiniTool Partition Wizard to move the partition and make the unallocated space contiguous with the C drive before extending it. Always be cautious when making changes to disk partitions, and make sure to back up important data before performing such operations.
