When SQL Server was Restarted ?????

Generally we use the following commands to find out when SQL Server was restarted

SELECT create_date  FROM sys.databases
WHERE database_id = 2 -- (TempDb)

SELECT start_time  FROM sys.dm_exec_requests
WHERE (session_id = 1)

SELECT login_time FROM sys.sysprocesses
WHERE (spid = 1)

SELECT MIN(login_time)  FROM sys.sysprocesses

From Now Onwards

SELECT sqlserver_start_time  FROM sys.dm_os_sys_info
