I have a 2007 Sony notebook running Vista Business with all updates. After bootup, after about 2 minutes, the hard drive is accessed continuously for 30 to 45 minutes. I have "What is my computer Doing" installed, and it shows SVCHOST.exe is continously accessing the HD. I've turned off indexing. I searched for a solution, but the only thing I found applies to XP. I don't want to install it and cause further problems.
I tried locating WUAUENG.DLL but can't find it in Widows/system32/ or anywhere else on my hard drive.
