<#
.SYNOPSIS
This is a modification of Microsoft's "Decline-SupersededUpdatesWithExclusionPeriod.ps1" script.
.DESCRIPTION
The problem with Microsoft's script is it tries to retrieve all updates at once. If you have a large amount of updates in your WSUS databse this may cause a timeout.
This script allows you to decline superseded updates by date and time, down to the millisecond if necessary.
.PARAMETER computerName
The hostname of your WSUS Server.
.PARAMETER startDate
The start datetime to start excluding updates. e.g. '2017-05-08 23:21:00'
.PARAMETER endDate
The end datetime to finish excluding updates. e.g. '2017-05-08 23:25:00'.
This datetime should be after the startDate
.PARAMETER steps
The amount of iterations to run, used with interval.
.PARAMETER interval
The amount of time in seconds the script should add to the startDate and endDate
.EXAMPLE
.\Remove-BADWSUSUpdates.ps1 -computerName 'WSUSServer01' -startDate '2017-05-08 23:21:00' -endDate '2017-05-08 23:25:00' -steps 2 -interval 20
This would pull all updates between 2017-05-08 23:21:00 and 2017-05-08 23:25:00 and then decline them. Because there are two steps and the interval is 20, it would then
add 20 seconds to both dates, pull the updates again, then decline them
e.g. Step 1. (updates between 2017-05-08 23:21:20 and 2017-05-08 23:25:20)
e.g. Step 2. (updates between 2017-05-08 23:21:40 and 2017-05-08 23:25:40)
