Retrieves SQL Server installation dates by querying system tables for compliance auditing and infrastructure tracking.
Queries system tables (sys.server_principals or sysservers) to determine when SQL Server was originally installed on each target instance. This information is essential for compliance auditing, license management, and tracking hardware refresh cycles. The function automatically handles different SQL Server versions using the appropriate system table, and can optionally retrieve the Windows OS installation date through WMI for complete infrastructure documentation. Returns structured data including computer name, instance name, and precise installation timestamps.

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
