How can anyone change the volume GUID as it is shown in mountvol system command?
For example, instead
\\?\Volume{fc00ffd7-33b7-48ba-bddf-0a645f93feac}\
C:\
I want to set it
\\?\Volume{e30f0393-0000-0000-0000-010000000000}\
Windows 10 Version Professional 2004
Thanks,

First, you don't really-really want to change it.
But if you really-really want to change it, I believe you cannot choose a "random" one, it must be a valid UUID v1, see:
http://reboot.pro/to...vices/?p=208998
uuid -d e30f0393-0000-0000-0000-010000000000
encode: STR: e30f0393-0000-0000-0000-010000000000
SIV: 301812711989822626115461059320802705408
decode: variant: reserved (NCS backward compatible)
version: 0 (unknown)
content: E3:0F:03:93:00:00:00:00:00:00:01:00:00:00:00:00
(not decipherable: unknown UUID version)
Then, it depends on whether the disk is MBR or GPT.
If the disk is MBR the UUID is stored in the Registry only, if it is GPT it is also stored on disk.
You can try changing it (in the given thread there are references to where the value in the Registry and in the GPT partition table) but I doubt it can work unless it is a valid, well formed UUID v1:
