Windows 11 left and empty 93GB partition?

When I installed Windows 11, it was on a blank 1TB NVME drive with no partitions. After the installation I am left with four partitions.

 

 

Disk Manager shows the following:
#1 = 100 mb EFI partition
#2 - 837 gb C:
#3 - 93 gb unallocated partition
#4 - 749 mb unknown partition (recovery? Does Windows user this space when doing a reset?)

I opened Diskpart to try to assign a letter to partition #3, but Diskpart does not agree with Disk Manager. There is no 93gb partition listed.

 

Why would windows leave a 93 gb unallocated space on my drive? Why doesn't Diskpart and Disk Manager agree with each other? Can I grow my 837 gb partition using the 93 gb space?

    Go to the disk management app, format the unallocated partition and assign a new drive letter to it.

    Open Disk Management:

    Right-click on the Start menu and select Disk Management.
    Here, you can see all the drives and partitions available on your system.

    Identify the Partition:

    Find the 93GB partition in the Disk Management window. Look at its status—if it’s labeled as "Unallocated," it hasn’t been formatted yet. If it has a drive letter but appears empty, it may not have been used properly.

    Options for Unallocated Space:

    If the partition is unallocated, you can create a new partition in that space:
    Right-click on the unallocated space and select New Simple Volume.
    Follow the wizard to format the partition and assign it a drive letter.

      When you install Windows 11 on a blank drive, it automatically creates four partitions: the EFI System Partition (for booting), a Microsoft Reserved Partition, the Windows partition (for your OS and files), and a Recovery Partition (for system recovery).

    You can format the partition to take advantage of the unallocated free space. After that, the space will be available for saving data.

    Do not delete or mess with the system or recovery partitions, as they are crucial for booting and recovering your Windows installation.

    If you want to increase the size of your main (C:) partition, you can right-click on the C: drive and select "Extend Volume." Follow the prompts to incorporate the unallocated space into the C: drive.

    After installing Windows 11 on a blank 1TB NVMe drive, it's common for the operating system to create multiple partitions for various purposes, including recovery, system files, and user data. It sounds like you have a partition that is left empty, which can be confusing.
