as its name implies, svchost is a process that handles multiple services - these services are grouped into each of several host processes, so you may see 5 or 6 svchost processes running. in task manager you can see which partic host is running hot.. and that is all. you need more software to go deeper to see which service is causing the problem - just stopping that partic svchost can cause all sorts of mayhem. So [i gotta stop pushing this software...] go to sysinternals [don't be surprised to see it is now part of M$] and get ProcessExplorer. Unzip it into its own folder and run it by dclicking the exe. Read the webpage, the help file and then go to it and find the bad service. it may be corrupted or just locked in a loop cos it cannot complete. Stop it and see what happens. tell us what you find. Please.
