Microsoft Help Desk Left Me With Too Many User accounts.

My laptop, with Windows 10, is 17 months old and for some reason, was still on v1803 which was installed in July 2018. A couple of months ago, a notice appeared in Windows Update saying "Feature update to Windows 10, version 1930.The Windows 10 May 2019 Update is on its way. We're offering this update to compatible devices, but your device isn't quite ready for it. Once your device is ready, you'll see the update available on this page. There's nothing you need to do at this time."

A couple of weeks ago, I noticed that the message had disappeared. I checked my history and it was showing two failed attempts to install v1903. I run Windows Update often but never was given the option to install v1903. Did some trouble shooting but nothing I did would enable me to install v1903. I phoned Microsoft and they remote accessed in and tried to fix the problem. The person (I will call him 'He') said that he could not find the reason for what was happening and he would need to reinstall Windows. I had taken an Image Backup before phoning them.

When it came to choose one of three install option, which are: 1. Keep personal files, apps and Windows settings. 2. Keep personal files only. 3. Nothing.
Option (1) was greyed out and could not be chosen. He did option 2.

At the end of it all, I have been left a bit puzzled. I realized today that my documents, music, etc, that I keep on a second internal drive (D:) were not showing up when I used Search. Looking at the Indexer, I see that it only listed " Internet Explorer History, Start menu & Users". I know that under "Modify", I can select the D drive and it will index it. That is no problem.The problem is that when I choose, from the Search box options, index/choose which files and folders are indexed, I scroll down and find these accounts are showing (I will try to embed a Screen Snip):



C:\Users\adair\
C:\Users\Administrator\
C:\Users\Default\
C:\Users\Trevor

I look in C:\Users and find listed: Administrator, Public & Trevor. Trevor is what I use on this laptop, with Administrator rights. All my files are under that name.
On two other Window 10 laptops, I find on (1) C:\Users Bren and Public (2) C:\Users adairs and Public.

Under the indexing options of (1), under "choose which files and folders are indexed", is shown C:\Users\bren\
(2) C:\Users\adairs & Public.

I have no idea what he did to mine, so can I have some advice on what I need to do & how to do it, to get rid of the Users I don't need?

As there has been no answer to my question, I left things as they are. Slowly reinstalling my programs and find that I need to get the "Lenovo Vantage" app from the Microsoft Store. The laptop had it installed from new. I find that I cannot login to the store. I can log in to my Microsoft account online but not the store. I am currently following the advice from Greg Carmack-Windows MVP from a post of his on the Answers.Microsoft support site. I think I will end up having to do a reinstall but hope something in his post will fix the problem. https://answers.microsoft.com/en-us/...d-59ec8527edff

In case anyone is interested, I ended up doing a Custom Install, which fixed my problems. I am rather disappointed that there has been no support from this forum. This is a first for me as I have had excellent support in the past.
