#Requires -Version 4.0 # https://github.com/AngleSharp/AngleSharp # https://github.com/AngleSharp/AngleSharp/blob/master/doc/Basics.md function Get-SQLServerUpdate { <# .Synopsis Returns available update list for SQl Server .DESCRIPTION Returns available updates list (cumulatvie update, service pack) for SQL Server. Source for updates list - http://sqlserverupdates.com/ Additional information. When I wrote this script I had a problem with Exception 0x800A01B6, some tips for me were at this site: https://www.sepago.com/blog/2016/05/03/powershell-exception-0x800a01b6-while-using-getelementsbytagname-getelementsbyname. In the script I use IHTMLDocument3_getElementsByTagName instead of method getElementsByTagName. I recommend to use the script at client stations, but I encourage to make a test at servers alternatively.
