C drive name change

[LEO31]

I upgraded my computer from Windows 7 to 10 about 6 months ago. It is partitioned with 10 on C drive and XP on D drive.
but it still shows C Drive as windows 7, although it is running 10 .How can I change the title to Windows 10 without upsetting anything?

Whether it's the right way or not. I just click on the desktop icon "This PC" right click on the drive you wish to change and select rename (not the assigned drive letters) and rename XP to Win 10 click OK that's it.
