Renaming folder in Windows 10

[Clive]

It's a bit embarrassing asking such a simple question but I'm trying to rename a folder and there doesn't seem any provision to do so!  I made a new folder in which to transfer the contents of my netbook.  Normally I would right click on the folder and click rename.

I've unpinned it and the option to rename it appears, but it says the folder is open.

A reboot cures everything!

Glad to see you found our self-help group, Clive.

I was always told that talking to oneself is the first sign of madness.  I passed that stage years ago.
