'Get base WMI object, "." means computer name (local)
Set oWMI = GetObject("WINMGMTS:\\.\ROOT\cimv2")

Do
  'Get the instance of Win32_DiskQuota 
  Set Instance = oWMI.Get("Win32_DiskQuota.QuotaVolume=""Path to Win32_LogicalDisk"",User=""Path to Win32_Account""")
                    
  'Do something with the instance
  Wscript.Echo Instance.DiskSpaceUsed 'or other property name

  'Wait for some time to get next value
  Wscript.Sleep 1000
Loop While True  
  

WMI query - sample windows WQL

'http://wutils.com/wmi/
Dim oWMI, WQL, Instances, Instance

'Get base WMI object, "." means computer name (local)
Set oWMI = GetObject("WINMGMTS:\\.\ROOT\cimv2")

'Create a WMI query text 
WQL = "Select * from Win32_DiskQuota"

'Get instances of Win32_DiskQuota 
Set Instances = oWMI.ExecQuery(WQL)
                    
'Enumerate instances  
For Each Instance In Instances 
  'Do something with the instance
  Wscript.Echo Instance.DiskSpaceUsed 'or other property name
Next 'Instance

InstancesOf

List of all instances, wmi class Win32_DiskQuota.

'http://wutils.com/wmi/
Dim oWMI, Instances, Instance

'Get base WMI object, "." means computer name (local)
Set oWMI = GetObject("WINMGMTS:\\.\ROOT\cimv2")

'Get instances of Win32_DiskQuota 
Set Instances = oWMI.InstancesOf("Win32_DiskQuota")


'Enumerate instances  
For Each Instance In Instances 
  'Do something with the instance
  Wscript.Echo Instance.DiskSpaceUsed 'or other property name
Next 'Instance

WMI remote scripting - Locator, Connect
