How to Remove SMS Advanced Client using msiexec /x

We had meet one scenario from one of the customer, we are trying to remove SMS Advanced Client from one of the Windows XP machine using Ccmclean tool (Ccmclean tool can be found in SMS toolkit). But unfortunately, it failed to remove the client by using Ccmclean.There is another method to remove the SMS Advanced Client from the machine which is msiexec /x command.Before executing that command, you must know what is the GUID for the SMS Advanced Client, the GUID value can be found inside the Registry editor under following registry key:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\UninstallThe correct GUID has SMS Advanced Client as the Display Name value.After you get the SMS Advanced Client GUID value, execute the msiexec /x command at command prompt.Msiexec /x {D8EF2D11-47CF-45E5-B423-47B29706DE12}(the value behind Msiexec /x indicate the GUID of SMS Advanced Client)After you execute the Msiexec /x on the machine, you may need to manually remove the VPCache folder for SMS Advanced Client. Below is the step by step how to complete the task:1. Locate the following registry key in registry editor:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\VPCache2. The Path value for VPCache is the location of the VPCache folder on the system drive. For example, %Windir%\System32\VPCache.3. Locate the VPCache folder and then delete it from the hard drive.4. Lastly, delete VPCache registry key from the registry editor.Although this method need to spend more time to complete it, but it is a alternative for you to remove the SMS Advanced Client from the machine, no harm to have a try. :)P/S: Please use Registry Editor with extra careful, or else it may crash your system. :)
