Although Windows 11 has been released for many years, many people still use Windows 10 on their desktops or laptops. To manage disk partitions and maximize disk performance, you need a reliable partition manager for Windows 10, no matter whether you use a mechanical HDD, an SSD (Solid State Drive), or even RAID arrays. There are two types of free partition managers for Windows 10/11 computers.
If you just want to initialize a brand new hard disk, create, delete, and format partitions, Windows 10/11 has a built-in Disk Management utility to help you. If you want to resize, move, merge, clone, convert, defrag, wipe, or hide partitions, third-party partition manager software is needed. This article introduces both the native free partition manager in Windows 10/11 and the best free partition software for Windows 10/11 computers.

Native Free Partition Manager in Windows 10/11
As with previous versions, there is a native free partition manager in Windows 10/11 - Disk Management. It is able to create, delete, and format partitions, set Active, and change drive letters. For advanced users, it has Shrink Volume and Extend Volume functions to help change partition size.
However, if you want to extend the C: drive by shrinking D or another volume, Disk Management cannot help you, because the unallocated space shrunk from any volume is non-adjacent to the C: drive, so Extend Volume is greyed out. If you want to do that, disk partition software is needed.
To open Disk Management in Windows 10/11:
- Press Windows + X together on your keyboard and then click it from the list.
- Press the Windows + R keys together, input diskmgmt.msc, and press Enter.
Windows 10/11 Disk Management can convert a disk between MBR and GPT, but you must delete all partitions on this disk in advance. Right-click each partition or the front of a disk in Disk Management, and you will see all options; unavailable operations are grayed out.
Best Free Partition Software for Windows 10/11
There are many free partition software options for Windows 10/11 on the market; both their designs and functions are similar, so how do you select the right tool for your own computer? The most important aspect is data protection ability, because there is a potential risk of system and data damage while repartitioning a hard disk drive. The second aspect is speed; nobody likes a tool that takes a long time to resize, move, copy, or perform other operations.
Among these disk partition managers for Windows 10/11, NIUBI Partition Editor is recommended by many editors and end users. It has a free edition for Windows 11, 10, 8, 7, Vista, and XP (32 & 64-bit) home computer users. It is 100% clean without any bundled plugins or advertisements.
