How to get the current username in Windows Powershell?
Found it:
[Environment]::UserName
There is also:
[Environment]::UserDomainName
[Environment]::MachineName
When you use the Get-Credential cmdlet, you get a GUI dialog box to enter the credentials. This is the "Common Criteria Certified" way of handling credentials. It is also a pain in the butt at times. If you are an admin, you can alter this and request credentials via the command line as follows:
PS> $key = "HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds"
PS> Set-ItemProperty $key ConsolePrompting True
PS> Get-Credential
cmdlet Get-Credential at command pipeline position 1
Supply values for the following parameters:
Credential
User: ntdev\jsnover
Password for user ntdev\jsnover: ******
UserName Password -------- -------- ntdev\jsnover System.Security.SecureString
Enjoy!
[System.Security.Principal.WindowsIdentity]::GetCurrent().Name
