If you’re not aware, you can manage your SCCM maintenance Windows using PowerShell.
Here’s a simple example but you can get creative.
#Import SCCM Module
$SiteCode = Get-PSDrive -PSProvider CMSITE
# Set Location to SCCM
#Occurs Fourth day of every 3 months effective the time you create it at 3:00 AM
$Schedule = New-CMSchedule -DurationCount 1 -DurationInterval Hours -RecurCount 3 -DayOfMonth 4 -Start ([Datetime]”3:00″)
$Collection = Get-CMDeviceCollection -Name “Your Collection Name”
New-CMMaintenanceWindow -CollectionID $Collection.CollectionID -Schedule $Schedule -Name “Your Schedule Name”

You can also verify if your maintenance windows has been configured properly in your collections with the report Configuration Manager – Collections.
Simply sort by the maintenance windows column.
