How to Extend Windows 10 Partition to Free up Space

  • Contents:

    Question: since Windows 10 Technical Preview was available, I downloaded the 64 bit version and dual boot it in Windows 7. Nevertheless, the partition which saves Windows 10 now does not have much free space left (I just allocated it with 25GB capacity at the beginning of time), and I even could not take space from its neighboring partitions to enlarge it in disk management. Who can give me an easy way to extend Windows 10 partition? Much appreciate.

    Answer: since Windows built-in disk management tool and the diskpart utility extend a primary partition only with contiguous unallocated space on the right side (logical partition with free space), users need to download a partitioning tool which can be compatible with Windows 10 well. Here, MiniTool Partition Wizard is recommended, because we have used it to partition hard disk under Windows 10 for many times. It extends Windows 10 partition by taking free space from any other existing partitions or unallocated spaces on the same disk and will not bring any damage to the original data. Let’s see detailed steps.

    How to Extend Windows 10 Partition with MiniTool Partition Wizard


    Firstly, download and install the partitioning tool on Windows 10. Then, launch the program to get the interface below:



    Here, please select the Windows 10 partition and choose “Extend Partition” function from the left pane.



    Then, choose a partition or unallocated space to take free space and drag the sliding handle to decide how much free space to take. After that, click “OK” to go back to the main interface:



    Now we can see the Windows 10 partition is enlarged, but this effect has not been applied to computer, so users need to click on “Apply” button to execute all changes. Once the application is completed, to extend Windows 10 partition will be done.

    Therefore, when your partition which saves Windows 10 or other Windows operating systems is short of free space, try using MiniTool Partition Wizard to extend it.

    Note: if the Windows 10 partition is being used (Windows 10 is running), users will be asked to restart computer, and then the partitioning tool will perform changes in boot mode.
