I just wanted to make a couple of corrections because I noticed some incorrect terminology used a few times that could lead to confusion:
There is more than one partition some are referring to as a "reserved" partition so it's important to differentiate between them.
The System Reserved partition is typically about 500 MB in size with Win 10+. The size can vary a bit, that's a typical value. Note that only an MBR disk has a System Reserved partition. On a GPT disk, this partition is known as the Recovery Partition which holds the Recovery Environment (Windows RE).
The MSR or![Smile :-) :-)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
The EFI partition on a GPT disk is 100 MB except in the case of an Advanced Format 4K drive because the minimum FAT32 partition size on this type of disk is 260 MB. For use with scripts or unattended installs I always specify a size of 260 MB to guarantee that it will work on any disk.
With all that said, the real question in my mind is this: On a system with so much available free space in the primary partition, why would a 16 MB partition (one sixty-fourth of a GB) even concern you? I would be far more inclined to leave it alone unless I was somehow desperate for space, but that's just my opinion![Smile :-) :-)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)

eserved partition is the 16 MB partition on a GPT OS drive and is unformatted. On non-OS GPT disks, the MSR is 128 MB for disks larger than 16 GB, 32 MB for disks smaller than 16 GB. You can typically delete this partition, it's considered "Reserved for Future Use", so if you prefer upgrades installs rather than clean installs, there is a possibility that you may one day find Microsoft using this partition, but who knows what they will do ![Smile :-) :-)](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f642.png)
