Configuration Manager Module - modify expanded property?

Question

I am playing around with the Configuration Manager module  - specifically I am trying to modify properties of a maintenance window. 
If I run: get-CMMaintenanceWindow -collectionID xxxxxxxx
It pulls back the collection by the ID and displays some other properties (duration, name, description, etc). I am interested in modifying the property called "IsEnabled". I can narrow down to this property by piping into:  | select -expandproperty
"isenabled"
How can I modify this expanded property? Currently the value is $true but I want to set it to $false (then eventually back to $true)
I don't think I am getting creative enough. Any suggestions?

Answer 1

I am stuck.
I can query via cmdlets and acquire a collection's maintenance window and view all the properties - but cannot modify the IsEnabled (or haven't discovered how yet)
Get-CMDeviceCollection -name "sccm-mw-prod - 1we*" | select -expandproperty collectionid | foreach-obj
ect {Get-CMMaintenanceWindow -CollectionId $_ } | select *
As suggested, I started digging into WMI. I was able to pull collections by name and get their members
query for collections with "1we" in the name
gwmi -class sms_collection -namespace "root\sms\site_xxx" | where name -like "*1we*" | select name,collectionid
If I put the above line into variable $test and pipe it like so, I can get the members of each collection
$test | foreach-object {gwmi -class sms_collectionmember -namespace "root\sms\site_xxx" | where classpath -lik
e "*$_" | select name | sort}
NOW, if I take $test and change the query so it selects * instead of just name and collectionID - I can't find any properties that indicates maintenance/service window. All I see is one that says 'ServiceWindowsCount' which is useless.
$test = gwmi -class sms_collection -namespace "root\sms\site_xxx" | where name -like "*1we*" | select *
I then started playing around with a different WMI class called "sms_servicewindow". 
$test2 = gwmi -list -namespace "root\sms\site_xxx" | where name -like "sms_servicewindow"
If I type: $test2.properties I get a list of properties but they seem like a generic list; aka, they don't pertain to a specific maintenance/service window. I do see familiar properties like IsEnabled, description, duration, etc. I could be wrong though.
*Ultimately, I would like to have a script that I could pass certain collections to and it would set the "isenabled" field for their maintenance windows to $false instead of $true. If we need to delay patches for a specific weekend, I don't want
to have to manually go in to each window and disable it by hand - I can just run the script. This doesn't seem possible unless I am missing something. 
Any help is appreciated!
EDIT: and of course, if there was an easier way in the GUI to select multiple collections and disable all of the maintenance windows I would use that too - doesn't have to be a script. But I haven't found any other way to do this in the GUI besides manually
doing it to each collection > MW.
