Limitation: The volume size is displayed in megabytes (MB), which can be a tedious step for users to deal with.
1. Enter into the Windows 10 Disk Management interface.
To access the Disk Management tool in Windows, you can either use the search box and type "Disk management" to find the "Create and format hard disk partitions" option, or use the Power User menu by pressing the Windows key + X and selecting "Disk management" from the menu.
2. To create unallocated space on a hard drive, right-click the hard drive and select "Shrink Volume". This will free up space on the drive, which can then be used for other purposes.
3. Right-click on the unallocated space, select "New Simple Volume", click "Next" and specify volume size.

How to Do Disk Partition in Windows 11/10 with a Free Partition Manager
Qiling Partition Master allows you to create, resize, move, and merge partitions on a hard drive, either a new one or one you're currently using.
This software does not have the disadvantages of the previous two parts due to its simplicity and flexibility in allocating space.
If your computer has unallocated space on the disk, you can create new partitions directly. If it only has one C partition, you can adjust the C drive and then create a new partition on the free space.
Step 1. Check for free space
To divide a disk partition into multiple ones, ensure there is enough free space to allocate.
Step 2. Shrink a disk partition to create unallocated space
To resize a partition with a lot of free space, start by clicking on it and selecting the "Resize/Move" feature. This will allow you to adjust the partition's size.
To make room for more unallocated space, drag either end of the partition to the right or left, reducing its size as indicated by the red arrow, and then click "Proceed".
To finalize the disk shrink, check the warning message and click "OK" to confirm the changes. Then, go back to the main window and look for unallocated space under the same disk where the shrink occurred. This should now be visible.
Step 3. Create a new partition on unallocated space
To turn the unallocated space into a usable partition drive with a recognized file system, click on the unallocated space and choose "Create".
In the Advanced Settings, you can customize the partition information by selecting a drive letter, partition label, file system (such as NTFS, FAT32, EXT2/3/4, or exFAT), and configuring other settings.
To create a partition on unallocated space, select the unallocated space from the list, click "New" to create a new partition, choose the partition size, file system, and label, then click "Proceed" to confirm the partition creation. This process can be repeated to create multiple partitions on the hard drive.
