This reply is a bit confusing so I will chop it into bits

I misread the tutorial .
I thought I had to click on the default entry itself to get the delete menu.
I did not do it..
I decided to ask if ok. before I went that far.

I had Disk Cleanup on my list of things I must do.
While I was waiting I did the first option of that tutorial.
Steps 4 and 5 - ie one user plus Systems cleanup

Read your message re netplwiz
Investigated netplwiz and registry again.
Default User Granny C,,, had disappeared from Registry
Default value 0 had either only just appeared or I had only just noticed it.
Advised you accordingly

Meanwhile: TODAY
M...C....my full name appeared again on switch list of User Accounts on sign on to laptop page, instead of alias....
Checked Control Panel - M...C... was there as well linked to the alias.. email address.
Assume because my Microsoft main account is in that name.
Took fright in case it brought back the old problems.
Found I could rename myself on the main Microsoft Account so I did
Main name is now EM...SHUNT.... sort of anagram of my names.

My 2 new accounts were both Local when I first created them.
I found I needed a Microsoft Account so I had already changed alias to Microsoft User Account
I still have 4 User Accounts. The 2 belonging to my sons and 2 new onesThe new Local Account is called FUNF.The new Microsoft Account appears on the directory as alias...So far on sign on page I have all 4 of them.
The ghost of Granny does appear to have been laid but I am not holding my breath !
