Is this a new PC? Did this work at some point in time?
You might be running "Windows S".
Can you open a Powershell prompt and run these commands? (Copy and paste.)
Get-ComputerInfo | fl -Property WindowsProductName, OSDisplayVersion, OsName, OsVersion, OsBuildNumber
Get-LocalUser
If you can't run Powershell, then you probably have "S". Check the Edition.
