Find SQL Server Install Date

,

This script is compatible for both SQL 2000 and SQL 2005. This is handy script which could be used to find the SQL Instance install date. For SQL 2005 it lists out the individual install date like SQL Server, Integration Services.

 

Note : if there exists problem copying the code directly to Query Analyzer or SSMS. Please copy it to wordpad/Word, from there copy to your query window.
