Just to let you know that recently I'm having problem to edit some WMI Definitions (Menu - Options - Remote WMI). Some of them open, others never and just hang in there. Then the only way out is through task manager kill option.
Andrew here the Remote WMI definitions where NS is hanging:
1)
Checked=False
ItemName=DiskDrive_Caption_InterfaceType_USB
WQLStatement=SELECT Caption FROM Win32_DiskDrive WHERE InterfaceType = 'USB'
NameSpace=CIMV2
2)
Checked=False
ItemName=IEProxy
WQLStatement=SELECT IEProxy FROM NetDiagnostics
NameSpace=CIMV2
3)
Checked=False
ItemName=Process_Name
WQLStatement=SELECT Name FROM Win32_Process Where Name = 'TWebCamera.exe'
NameSpace=CIMV2
4)
Checked=False
ItemName=USBHub_Caption
WQLStatement=SELECT Caption FROM Win32_USBHub WHERE NOT Caption LIKE '%root hub%' AND NOT Caption LIKE '%generic%' AND NOT Caption LIKE '%composite device%' AND NOT Caption LIKE '%usb mass%' AND NOT Caption LIKE '%usb printing%'
NameSpace=CIMV2
Sorry it doesn't happen here. I tried on several different versions of Windows. It could be something the WMI sub-system is waiting for, interference from antivirus or something else.
I can only recommend to try to wait longer or try this on a different computer.
