How to Increase EFI System Partition Size in Windows 10

I do not want to remove the Windows Recovery Partition, and I want to increase the size of the EFI System Partition to 500MB. But, I don't know how to move the unallocated space right behind the EFI system partition as the 'extend volume' button is greyed out now.

Due to the Windows system limitation, users can't increase the EFI system partition size unless there is adjacent free space after it. Luckily, EaseUS Partition Master Professional will help you enlarge the EFI partition no matter if there is any continuous unallocated space. It offers three options for various scenarios:

Option 1. Increase EFI Partition with Unallocated Space

To apply its "Resize&Move" feature, ensure you have unallocated space on the hard drive(it doesn't have to be next to the EFI partition.)

Step 1: In the Partition Master tab of this tool, right-click on the EFI system partition and select "Resize/Move."

Step 2: To add space to the EFI partition, drag the system partition end into unallocated space and select "OK."

Step 3: Pick "Execute Task" > "Apply" to extend the Windows recovery partition.

Option 2. Increase EFI Partition without Unallocated Space

Its "Allocate Space" function is for users who don't have free space on the system disk:

Step 1. Right-click on any of the other partitions with enough free space and select "Allocate Space."

Step 2. Select the EFI partition and drag its panel rightward to add the free space from another partition. Then click "OK" to verify.

Step 3. Press "Apply" after selecting "Execute 1 Task" to transfer free space from another partition to the EFI system partition.

If there is enough unallocated space on your system disk, you can follow this tutorial to extend the EFI partition using EaseUS Partition Master, Disk Management, and Diskpart:
