Why Windows XP takes so long to shut down

[bhxtyrant]

Hey guys,I was just wondering if anyone has had any trouble using MSN messenger 8 and skype after installing this?I installed it the other day because like others my XP takes a few minutes to shut down.After i installed i tryed to use both MSN and skype.When in skype calls i get kicked after a time that seems to vary from seconds to around 10 minutes i also notice that MSN seeems to kick me offline at the same moment.I uninstalled this service but the problem now plagues me.All was working fine before installing this service

I havent installed any new software other then 3 windows updates so i dont know what else could be causing the problem.

Just for reference the windows updates were-
MS06-036: A vulnerability in the DHCP Client Service could allow remote code execution
MS06-035: Vulnerability in Server service could allow remote code execution
Stop error message on a Windows XP-based computer: "STOP 0x000000D1"

I just did a system rewstore to the day before i installed hive cleanup but i notice the windows updates and other new updates i installed for skype yesterday and firefox yesterday remained.Hope it fixes the issue.
