How to change IGMP Version (IGMP v1/v2/v3) in Windows XP PC?

By default when the Windows XP host joins IGMP group it uses IGMP v3. If you want to change this behavior and want PC to generate IGMP v1 or v2 messages change the registry settings as follows:

1) Start -> Run -> regedit

2) Go to HKEY_LOCAL_MACHINE ->SYSTEM->CurrentControlSet->Services->Tcpip->Paramters

3) Right Click -> New-> DWORD Value-> Rename the field as  "IGMPVersion"

Set the Value according to the table below and reboot the PC.  

Value "2" ->  IGMP Version 1

        "3" -> IGMP Version 2

        "4" -> IGMP Version 3 ( Default)
