For the last two years, we’ve just had workstations in our SCCM environment, and now we are starting to bring in the servers. The server teams have a patching schedule and there are quite a few of them. They also change every month, they always relative to Patch Tuesday and have different reboot times. As a solution, we’ve setup a folder to put all the collections in and use a naming convention of “Patch Day NN ???? Reboot HH:MM”
So, I have a script I use, I’m publishing it now, but I confess, I want to do some polishing. I’d like to make it a little more efficient, but in the meantime, here it is. You can download it from my bitbucket link, or copy and paste from below. I’ve tried to put as many comments in there as I could, when I update the script, I’ll repost.

<# .SYNOPSIS This script sets non-repeating maintenance windows for patches that are realtive to Patch Tuesday on collections in a folder based on their name for the current month. .DESCRIPTION This script will get all the collections in a folder, if they match a naming convention of "Patch Day NN ??? Reboot NN:NN AM" it will set a non-repeating maintenance window on the collection. Considerations: The maintenance window will ALWAYS start on the relative day, so if you put Patch Day 01, the maintenance window will start on Patch Tuesday. If the reboot time is at 3:00am and you are using a 4 hour MaintenanceWindowDurration, the window will start on the relative day and reboot at 3:00am on the FOLLOWING day. I confess I haven't tried every possible combination for the collection names, so errors could result, but if you follow the pattern shown here, you should be succesfull I log the setting of the maintenance windows as a warning, so if use the defaults, only the Maintenance window changes would be logged. When the maintenance window is set, any existing maintenance windows will be deleted.+ .PARAMETER SiteServer ConfigMGR site server. This is where the SMS Provider is installed to connect to the site database .PARAMETER MaintenanceWindowDuration Duration, in hours, to make the maintenance window. The default is 4, but can be from 1 to 6 hours .PARAMETER LogLevel Sets the minimum logging level, default is 1. 1 - Informational 2 - Warning 3 - Error .PARAMETER LogFileDir Directory where you want the log file. Defaults to C:\Temp\ .PARAMETER ClearLog This will clear the log if it exists .EXAMPLE Set-CMNSUMaintenanceWindow -SiteServer CMNSVR01 -MaintenanceWindowDuration 5 -ClearLog This would work on CMNSVR01 and set the maintenance windows that are 5 hours long. It would also clear the log file if it existed .NOTES .LINK http://configman-notes.com #> PARAM ( [Parameter(Mandatory=$true,HelpMessage='Site Server')] [ValidateScript({Test-Connection -ComputerName $_ -Count 1 -Quiet})] [String]$SiteServer, [Parameter(Mandatory=$true,HelpMessage='Container to set schedules in')] [String]$ContainerName, [Parameter(Mandatory=$false,HelpMessage='Duration of maintenance window in hours (1 to 6)')] [ValidateRange(1,6)] [Int32]$MaintenanceWindowDuration=4, #Parameters in script for New-LogEntry [Parameter(Mandatory=$false,HelpMessage="Sets the Log Level, 1 - Informational, 2 - Warning, 3 - Error")] [Int32]$LogLevel = 2, [Parameter(Mandatory=$false,HelpMessage="Log File Directory")] [String]$LogFileDir = 'C:\Temp\', [Parameter(Mandatory=$false,HelpMessage="Clear any existing log file")] [Switch]$ClearLog ) #Begin New-LogEntry Function Function New-LogEntry { # Writes to the log file Param ( [Parameter(Position=0,Mandatory=$true)] [String] $Entry, [Parameter(Position=1,Mandatory=$false)] [INT32] $type = 1, [Parameter(Position=2,Mandatory=$false)] [String] $component = $ScriptName ) Write-Verbose $Entry if ($type -ge $Script:LogLevel) { if ($Entry.Length -eq 0) { $Entry = 'N/A' } $TZOffset = ([TimeZoneInfo]::Local).BaseUTcOffset.TotalMinutes $TZOffset = "$(Get-Date -Format "HH:mm:ss.fff")+$(-$TZOffset)" $Entry = "<![LOG[{0}]LOG]!><time=""{2}"" date=""{1}"" component=""{5}"" context="""" type=""{4}"" thread=""{3}"">" -f $Entry, (Get-Date -Format "MM-dd-yyyy"), $TZOffset, $pid, $type, $component $Entry | Out-File $Script:LogFile -Append -Encoding ascii } } #End New-LogEntry Function Get-CMNMWStartTime { <# .SYNOPSIS This function will calculate the Maintenance Window Start Time .DESCRIPTION Using the collection name, it will start the Maintenance Window on the day relative to Patch Tuesday.

This can be from 1 to 6 hours, default is 4.
