Best way seems to be via a .reg
file.
Which allows for a simple syntax of declaring Registry Changes, which can then be run via the command line.
Example File:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\0949b555-c22c-56b7-873a-a960bdefa81f]
"ShortcutName"="Pulsar Cool"
; Comment Comment
Then run via:
reg.exe import test.reg
Then we can check current values via:
Get-ItemPropertyValue "HKCU:\Software\0949b555-c22c-56b7-873a-a960bdefa81f" "ShortcutName"
If this is all done for HKCU
or Current User only values, then no admin perms are ever required
