Add Guest Account in Windows 10  

The repair install also worked for me.I stated in an earlier post (#14) that I had succeeded in converting a Normal User account to a Guest account. That report was true - but misleading.

Here's what actually happened. I transferred a Macrium system image from an older Dell Vostro to my new Asus. That Vostro had an unused Normal account. So, as a quick experiment, I simply converted that account to a Guest account with no password.

There were no problems at login. So I deleted the experimental Guest account. (Rule: don't delete anything on a computer without thinking about it for at least a year.) I created a new Normal User account, then converted it to a Guest account as suggested earlier by Brink.

That account had the instantaneous logout problems as seen by several users of this thread. So I was then forced to do a Repair Install as suggested by Brink. That solved the problem

I now have a follow-up question on the same subject.
The visitor account has been set up with a US keyboard (there was no option to specify otherwise at set-up), but the visitor is unable to alter this, as admin rights are needed. How do I, as administrator, change the keyboard for the visitor account to the UK version?

@MikeinGrange,

A Guest account cannot open Settings, but it can open Control Panel. You can add an input method in Control Panel > Language. You won't even get a UAC prompt.

Many thank to both Brink & Bree for their rapid responses. Problem now solved.
