Unknown original administrator name and password

Linda,

You'll stop being lost after you have logged back in to your normal account.

Just complete the recovery steps first.

Step 3 - Log into one of the new admin accounts
- This is just to test it & to use it for Step 4

Step 4 - Disable the built-in admin account [same tutorial as Step 1]
... Disable Built-In Administrator account - TenForumsTutorials
- You can now use any of the Options to do this. Option 1 is probably simplest because you can just copy what you need from the tutorial.
- You can now log out of the admin account and back into Bob or Linda.

Best of luck,
Denis

Linda,

So "the" problem has been resolved.
- You are back to signing in to your own user account.
- If you try to do something that needs Admin permission, a dialog pops up telling you to put in the name & password for one of your new Admin accounts.

We have several USB 'thingys'

- "Something with the flash drives"
I was just going to suggest that you run File explorer & select ThisPC then work though connecting each USB wotsit in turn to check how big it is and how much space you have used up. You can also check what 'filing system' is on each one. The most common filing systems are NTFS and Fat32.

This is one of my USB sticks.
- You can see the size 7.45GB [nominally, this is "8GB"]
- You can see how much space has been used [Size minus 'Free', so about 5.9GB]
- Over on the bottom-right, you can see that this one has the exFAT filing system [for particular reasons that are not common or at all interesting].

The point of checking is
- to see if you already have an 8GB USB with nothing on it [or nothing important] so I can guide you through making your own updated installation USB [later on, next month, next year, whenever you are interested, there's no point at the moment].
- to give me an excuse to nag you about backups.

Linda,

And if you do decide in the future that you want to make an installation USB of your own [after, say, the imminent Version 21H2 update] then just post in this thread again and I'll help.
- An installation USB is not just an installation tool; it can also be used as a useful repair tool.

Repair Install - TenForumsTutorials ***
Startup Repair - TenForumsTutorials
And a host of other minor tasks since it has a Command prompt and can run most of the normal Windows commands [old "DOS" commands].

*** Repair install notes
- A Repair install is also called an InPlace upgrade and is how many of us do the twice yearly Windows 10 Version updates.
- A Repair install is a repair task not a reinstallation. Your installed applications and data should never be affected even though backups would still be advisable.
