Windows 7: Notes on Windows 7 Service Pack 1 - Installed Early This Morning

Win7SP1 came up as a Windows automatic update last night so I installed it and have done three restarts and one more "check for updates" now to insure it has settled down. For major updates it is a good idea to watch the CPU Usage History graph in the Performance Tab of Task Manager so you know when all processes and services are fully loaded. I keep a shortcut to C:\Windows\SysWOW64\taskmgr.exe in the Start Menu>All Programs>Startup Folder so it automatically opens whenever Windows restarts.

Windows7 Home Premium x64 took about 3 min 7 secs to fully load. It appears SP1 has added about a minute to that as the CPU Usage History graph doesn't flatline for 4 min 2 secs. I load 70 processes, but that will vary for each user based on the software installed.

It took a while to find the release notes and a list of the 796 hotfixes and security updates included in SP1. They can be downloaded at

So far everything seems to be working great.

Documentation plus other info is already posted here. Just for FYI.

The only problem I experienced since installing SP1 was that I got a loud audio feedback and a frozen mouse for several seconds a couple times a day. It occurred when I was listening to music or podcasts with the latest versions of iTunes and Realplayer.

To fix it I went to Realtek and updated the Realtek High-Definition Audio Driver to R2.57 dated Jan 25, 2011. Haven't had a recurrence since.
