Windows 7 Very Slow To Start AND To Shutdown?

I went to restart after installing updates, and system was very slow to shut down, and very slow to start. I did run house call, and came up clean, also ran this one you download, but I can't find the shortcut to it, it was about 100 MB, the name was Kaspersky Virus Removal Tool, but came up clean as well.I did not time the shutdown yet, but did time the start up. If it matters it was broken down like this. It said "press escape for start up screen" for 40 seconds. Then "starting Windows" for 3 minuets.Then it said "welcome" for 40 seconds, Then a Black screen for 3 minuets. Then I got my desktop and start up sound. I was reading on line, where after a up date, something sometimes gets changed in the registry, where you have to change the Value from "1" back to "0" But that was OK. It was already at "0".I am trying to find the name of it, but of course I can not right now. Think it was "clear page file "I just now went to msconfig and the only thing new that was added was McAfee to start up, but I took it out of start up. I also have it disabled in my add ons (Firefox).Don't know if that could have been an issue, have not tried to shut down/restart yet. I have not installed any new hardware. I did put new batteries in my wireless mouse, that I don't use often. I am going to try and run CC cleaner next I guess.
