No admin permissions

Welcome to TenForums @survivor51

The 'net user' command can be used in a standard command prompt, it doesn't need to be an admin command prompt. The results are just a list of all accounts on the PC, it doesn't tell you anything about them. For that, you need to type the command net user accountname substituting each name from your list for 'accountname'.

Look for 'Account active Yes' and 'Local Group Memberships *Administrators' to identify an administrator account you can use at the "enter an admin user name and password'' prompt. By default the built-in Administrator account is not active, so you can't use that one.

It is unusual for an administrator account to have a password expiry date, especially if it was the only administrator account. By default the first account, created when you set up Windows for the first time, is an administrator with no a account expiry date. Any further accounts you create yourself would also have no expiry date.

Have you been changing any registry settings? I can't think of any other reason an account may have been set to expire. The only other plausible explanation would be that this is a business computer and the company's IT admin have put policies in place, but I would expect such a machine to have had Pro installed, not Home.

If it is indeed asking for the password of Guest as you said in post #1 then it seems to think it's an administrator. That should not be the case. Guest is a built-in account with less rights than a standard user. It should also be disabled by default. What does net user Guest say? It should look like this...

Code:

C:\Users\owner>NET USER GUEST

User name                    Guest
Full Name

Without seeing that screen it's very difficult to diagnose anything. We need some facts to work on.

You said in post #3 that you could...

...open cmd prompt and the words ''net user '' brought up this response...

but when asked to do it again, because you say it is asking for the Guest a/c password, you reply...

...seems everything i try brings up the same page that requires a password

For all we know it could be a malware infection that's producing that page. If you can't take a screenshot, use a camera.
