How to transfer logins and passwords from one SQL Server to another?

Hello all.
I needed to transfer logins and passwords from one of my SQL instance to another one.
I used this script, and i wanted to share with you all.

Run this Script and use the result on the server you would like to transfer the logins to.

SQL Server Uptime.

Hello

Today i wanted to check when i last restarted my Servers
I ran into this nice little script i would like to share with you all

SET NOCOUNT ON
DECLARE @crdate DATETIME, @hr VARCHAR(50), @min VARCHAR(5)
SELECT @crdate=crdate FROM sysdatabases WHERE NAME='tempdb'
SELECT @hr=(DATEDIFF ( mi, @crdate,GETDATE()))/60
IF ((DATEDIFF ( mi, @crdate,GETDATE()))/60)=0
SELECT @min=(DATEDIFF ( mi, @crdate,GETDATE()))
ELSE
SELECT @min=(DATEDIFF ( mi, @crdate,GETDATE()))-((DATEDIFF( mi, @crdate,GETDATE()))/60)*60
PRINT 'SQL Server "' + CONVERT(VARCHAR(20),SERVERPROPERTY('SERVERNAME'))+'" is Online for the past '+@hr+' hours & '+@min+' minutes'
IF NOT EXISTS (SELECT 1 FROM master.dbo.sysprocesses WHERE program_name = N'SQLAgent - Generic Refresher')
BEGIN
PRINT 'SQL Server is running but SQL Server Agent <> running'
END
ELSE BEGIN
PRINT 'SQL Server and SQL Server Agent both are running'
END

As a result i got
SQL Server "LOD-LT-ITAYL" is Online for the past 0 hours & 8 minutesSQL Server and SQL Server Agent both are running
