I don't know what programme you are trying to save from, but see if you can select:
"C:\Users\this is me\Desktop"
Where "this is me" is what ever user name you are using to log on.

Thanks, Bree. That works.

Thanks for your reply, Bree.
Post update I have Windows 10, Ver 1709 build 16299.175
Previously I had not updated since late last year, and if it were not for security worries, I would not update,...

After major update to Windows 10, I can no longer find the wifi status window which shows bytes sent and received.
Thanks for any assistance.
