Any button worked for me to continue, but the message box is just too annoying.
In other forums (with other versions of SQL Server) people reported that this issue can get worse ...
I have got exactly the same components and versions as yours.
Please excuse my silly question:
Did you replace the myname string in the path with your windows logon name?
Are you using a domain account? with roaming enabled?
We use domain accounts, but not roaming profiles.
I noticed that when I deleted both folders, after restarting SSMS the Shell folder in the Roaming tree got recreated immediately.
The corresponding folder in the Local tree got recreated only after some time - with the file CmdUI.PRF in it - Windows 7 recognises it as an Outlook preferences file (I suppose that is where "Office" in the caption of the error dialog comes from ...)
I hope my thoughts are helpful.
