Windows 10: Blue screen after trying to switch administrator account into guest account

I have to delete my Microsoft accounts from the computer which I decided to give to other person. I tried to delete an administrator account but at first I used netplwiz command to turn the Administrator account into a guest account and then I intended to delete it.

Currently I lost access to the system, Settings will not open and I see blue screen which flashes and closes.

How can I remove my accounts but save it functionality for further use?

Guest Account - Active but Can't Switch to or See in Users and Signon


I am running Windows 10 Home. I the cmd window I run "net user guest /active:yes" and the command completes successfully. I run "net user" and it shows 4 accounts---my account, administrator, guest and default account.
User folder has Guest sub-folder.

When I try to switch to Guest user from my profile picture in start, I get black screen, then login screen for my account. Guest does not show on my login screen, but is active. It is a fast login, like it is switching back to my account.

I cannot get at Guest account in login, switch user or in "Accounts" in settings.
I have tried all tutorials in Tenforums that deal with switching accounts Switch User in Windows 10. I have searched on the internet and tried all suggestions.

The only thing I have not tried is to illegally download gpedit.msc and run it to add "Group policies" in "Windows Features." That was offered as a solution, but I don't want to take the chance to try it (malware on download.)

Guest account worked fine in Vista, Win 8 and 8.1. Why is this such a mystery in Win 10? Anybody got a fix that works?
