Change name of GPT Partition (not label) under Windows from command line

Question

I need to change the name of a GPT partition (not a filesystem label), and I haven't found any way to do it under Windows, except for this tool.

The problem is that it's interactive and doesn't support being called from the command line, so no scripting is possible.

How else can I do it?

What do you mean by GPT "Name"? The UID of the volume? – bjoster Jun 13 '18 at 14:13 — bjoster, Jun 13 '18 at 14:13
@bjoster Yes. In Gparted it shows "name". – SuperJMN Jun 13 '18 at 16:22 — SuperJMN, Jun 13 '18 at 16:22

A partition name is a name given in the GPT; it's external to the partition itself. It is set when the GPT is created (automatically under Windows). A partition label is a string stored inside the filesystem; for example with ext-family filesystems, NTFS or FAT; this is the label you can manipulate with label/e2label etc.

The is no (supported) way to manipulated the GPT name under windows (directly). Under Linux it's done with

tune2fs -L vmguest_root /dev/sda1

tune2fs for Windows does not support changing the GPT name; it just supports chaning the feature bits of ext partitions.

Windows supports changing the label, not the name. Normally, the name of created GPT partitions should match the volume GUID.

So, there's no tool able to do (under Windows) that can be scripted? :( — SuperJMN, Jun 14 '18 at 18:42
No official supported ones, no. As far as I know there is a Win32 port of gdisk, but I don't know how good it is. Sorry. — bjoster, Jun 15 '18 at 10:09
