I noticed on rebooting today that the admin name was changed in the startup screen as well as under Accounts. In computer management I do not have a local user groups with an arrow next to it. How can I correct my admin name to what it was ?

I think I recall setting this machine up as a local account using a gmail address. I was able to use lusrmgr.exe to make the change in the start up screen but it hasn't changed in the upper left portion of the settings / system screen. I always wonder how these changes occur without being prompted.

Your Gmail Address in your account name IS your Microsoft Account, not a Local Account.
A Local Account is just a name you made up, with no Email address attached to the name. Please follow the instructions in Post #2 to change to a local account, if that is what you want.

Thank YOu. With a local account will I need to enter a password when I boot up ? Sorry for such a basic question but I am not at all familiar with this.

A local account is allowed to have a blank password, as mine does. At boot up it should go straight to the desktop, the most it will ever ask you is to click a 'sign in' button if you sign out and back in again, or lock the PC while you're away.

    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

That can happen, so I've heard. One of the reasons I prefer to have local accounts only. To benefit from having a Microsoft account as well I use this 'hybrid account' method.

Add Microsoft account to Local account for Hybrid account in Windows 11

A Microsoft account (MSA) is a good choice if a user wants to use the same account on multiple devices, or wants to make it easy to use all / any Microsoft services. Setting up a preinstalled Windows 10 on a new device, after a clean install, or creating a new user on existing Windows...
