Upgrade ConfigMgr Client Outside Maintenance Windows

A friend reached out to me recently about his environment as he was wondering why it was taking so long to upgrade the ConfigMgr clients when he set a 14-day window for the auto-upgrade function. In talking to him I learned he had many maintenance windows, even for workstation use case due to his companies work with some windows being once a month or even quarterly.

I pointed him to this uservoice as client upgrades honor maintenance windows and it is a request to allow upgrade outside of the maintenance windows. As a workaround, I shared an app we created to address for 1E Nomad in task sequences but which would work fine as it allows the client to be treated like any other application/package and pushed accordingly.

Create an application pointing to the stock source path located at

 \\MYSCCMSERVER.mydomain.com\SMS_SITECODE\Client\  

For the install program set to your defaults

 ccmsetup.exe /skipprereq:scepinstall.exe;silverlight.exe /forceinstall SMSCACHESIZE=10240 SMSMP=MYSCCMMP.mydomain.com SMSSITECODE=SITECODE  

Finally, for the detection method use a PowerShell script with the following.

 $VersionCheck = "5.00.8740.1024"  
 $CurrentVersion = $(Get-WMIObject -Namespace root\ccm -Class SMS_Client).ClientVersion  
 if ( $CurrentVersion -ge $VersionCheck ) {  
   Write-Host $CurrentVersion  
 }  

Note you need to update the version variable as you manage your environment. Super simple application. Just advertise to the relevant collection. Below is a query for what is not current. Need to modify the version portion to your environment as this is a not like 1810, including both rollups.

 select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System where SMS_R_System.ClientVersion not like "5.00.8740.1%"
