Works like a charm. Duly noted in my review. OK of course to close this ticket.
Many thanks for your quick reply. I had assumed from the initial log entry that the progam did just the one lookup when starting. You have clearly done your homework. Initial tests are promising indeed.
Correction: "As such..."
Question about functionality
Used the program to rename a Windows 10 Pro boot/OS partition with corrupted name. A cloud backup program (N-Able) was throwing errors. Tech Support said that this was the probable cause of the errors. Used GPT fdisk to rename the partition, rebooted without incident, and the N-Able backup then worked without error. Note: partition name is different than the partition/volume label in Disk Manager.
