GPT is short for GUID Partition Table; it is a standard for the layout of the
partition table on a physical hard disk. Compare with the Master Boot Record (MBR)
disk, GPT disk stands out in the following aspects:
Allows up to 128 primary partitions. MBR disk can only support four primary
partitions and an additional 124 partitions created in extended partitions
Allows the partition size greater than 2 terabytes (TB), which is the limit for
MBR disk
Provides greater reliability because of replication and cyclical redundancy
check (CRC) protection of the partition table
If using built-in Windows Disk Management to resize GPT disk partition we will get
some limitations. So, the latest AOMEI Partition Assistant provides
enhanced GPT disk management like resizing GPT disk partition,
extending/shrinking partition on GPT disk.
Step1. Download AOMEI Partition Assistant Demo
Step2. Install AOMEI
Partition Assistant Demo to follow
Launch AOMEI Partition Assistant to get the general GPT disk partition map:

In the new pop out window, drag the boundary (Both sides) rightwards or leftwards.
(P.S. For the better data protection or saving time, we do not recommend you to drag
the system partition left boundary rightwards)

All done, with AOMEI Partition Assistant, resize GPT disk partition is
not impossible but very easy and efficient. You also could resize partition, fix low disk space,partition hard
drive, merge partitions,split partition, create
partition and so on, it provides the straight operating wizards to accomplish all the
tasks.
