Why "Incorrect username and password when trying to run explorer as administrator"?

Question

System administration

Hello.
You need to run the explorer as Administrator, I tried everything, the only hope is this command:

runas /user:%computername%\administrator "explorer /separate"

I run cmd as administrator, enter it, press Enter, enter the password for my account (which I believe is the Administrator account), but the password is incorrect, although I entered it on the start window when logging in to my user in Windows 10
C :\Windows\system32>runas /user:%computername%\administrator "explorer /separate"
Enter password for EGORPC\administrator:
Attempting to run explorer /separate as user "EGORPC\administrator" ...
RUNAS ERROR: Unable to start - explorer /separate
1326: Invalid username or password.
What password should be entered if the password for the only created account is not suitable?

Answer 1

so according to the screenshot, Windows is Russian, maybe you have an "administrator" and not an "administrator"?

Answer 2

First, enter a command at the command prompt net userto find out what usernames are actually on the system.
Then, using what you learned in the previous step, compose a command to run explorer.exe with the correct administrator name.

Answer 3

runas /profile /user:%computername%\administrator "explorer /separate"

Answer 4

You can find out the username under which you are currently working using the command:
set USERNAME
By default, the standard user account Administrator (for Russian Windows) is blocked and cannot be used.
The only user of the system must have administrator rights, otherwise you could not install anything in Windows.
Since Windows has UAC, even if you run something under a user with administrator rights, you really don’t have these rights and you need to elevate privileges.
Using standard tools, you can increase the privileges of a program launched from a script using a powershell script (you can easily google it, it opens a window asking for privilege escalation) or using other third-party utilities (for example, nircmd, there are others).
