Windows 8 partition resize allows you to resize hard drive partitions under Windows 32 bit and 64 bit OS. Three methods here you can apply to resize Windows 8/10 partition: Partition Magic, disk management, and partition management software.

1. Resize with Partition Magic 

Partition Magic is a software utility for hard disk drive partitioning originally made by the Power Quest Corporation but owned by Symantec in 2003. The software runs on Microsoft Windows 98, Me, NT, 2000 and XP (Windows Server 2003, Windows Vista, Windows 7, Windows Server 2008. But Windows 8/10 is not supported by Norton Partition Magic), or cannot be boot from a bootable CD/DVD. Partition Magic has the capability of resizing, creating different drives (partitions) and other modifications to hard disk drives without losing any information on the hard disk drive.

You may still use Partition Magic. But it is so unstable that you will have great chance to encounter problems or system crash when resizing Windows 8 partition.

2. Resize with built-in Disk Management 

Yes! Windows 8 built-in Disk Management can shrink volume and extend volume.

Step1. Right click on "My Computer", choose "Manage", and you will get a popup window, choose "Disk Management" in the left navigation bar. And then, your hard disk condition will show as follow.

Step 2. Right click on the partition which you want to shrink, and choose "Shrink Volume", then type a number how much disk space you want to free up.

Step 3. Right-click the partition that you want to extend, choose "Extend Volume", and type the number of that unallocated space. Then the partition resize is done.

Although there is some improvement of the Disk Management Tool on Windows, it still has many limitations in partition management. (Please refer to the comparison table below). Because some advanced partition management in Windows 8 is still unavailable when you find your system partition is out of space which will be in red as below:

In this condition, people have to seek the best partition manager software. EaseUS Partition Master, a comprehensive free hard disk partition manager, and system optimization software for Windows-based administration works well with Windows 8.
