Hello. i use UI++ now for my W10 upgrade task sequences as well The "Preeflight" check is great for that!  Is there a WMI query with which I can determine the free space on the system partition ? Greetings, Mario |

Adding these two lines after a DefaultValues action where OS is specified as a ValueType will place the free space (in GB) in the variable YSystemDiskFreeSpaceGB:
<Action Type="WMIRead" Namespace="root\cimv2" Class="Win32_LogicalDisk" Property="FreeSpace" KeyQualifier="DeviceID='%XOSSystemDrive%'" Variable="YSystemDiskFreeSpaceBytes"/>
<Action Type="TSVar" Name="YSystemDiskFreeSpaceGB">Round(%YSystemDiskFreeSpaceBytes% / 1024 / 1024 / 1024, 2)</Action>
From there, you can add a preflight check like the following:
<Check Text="30GB System Disk Free Space" CheckCondition='%YSystemDiskFreeSpaceGB% > 30' Description="Only systems with at least 30GB of free space can be upgraded to Windows 10."
ErrorDescription="This system only has %YSystemDiskFreeSpaceGB%GB of free space and thus cannot be upgraded to Windows 10."/>
I will be adding a built-in DefaultValues variable for system disk free space in the next version so that will eliminate the need for the first two lines in the future.

Sorry, I don't quite understand your reply.
Single quotes or double-quotes are valid for XML attributes so either should work. For conditions, I often use single quotes because these conditions themselves include double-quotes.

Hi Jason, thats how it works <Check Text="30GB System Disk Free Space" CheckCondition='"%YSystemDiskFreeSpaceGB%" > 30' ErrorDescription="This system only has %YSystemDiskFreeSpaceGB%GB of free space and thus cannot be upgraded to Windows 10."/>
 So it does not work <Check Text="30GB System Disk Free Space" CheckCondition='%YSystemDiskFreeSpaceGB% > 30' ErrorDescription="This system only has %YSystemDiskFreeSpaceGB%GB of free space and thus cannot be upgraded to Windows 10."/>

Sorry, not sure what you are doing wrong, but copied exactly as I posted above works in my testing. Without seeing your log, I can't guess what's different but there is no need for the double-quotes around %YSystemDiskFreeSpaceGB%.

Any way to work with percentage of disk, instead of size? This would perhaps change which task sequence they run. Have 1 with usmt to the local drive, then if over 50% of disk used it would use task seq with server storage for usmt.

Sure, just use another TSVar action to gather the total space from Win32_Logical Disk and then in the check simply divide the free space by the total space and compare that to whatever percentage you desire.
