Windows 7: How do I fix "Superfetch"

How do I fix "Superfetch"

A Windows update was accidentally interrupted, resulting in Windows running extremely slow. I ran a diagnostic test/repair program from a Microsoft Support site. The results stated that several problems were repaired, but two problems remain. They are:
1. "SuperFetch" is not working properly
2. Several programs are running at the Startup
Windows is still running so slow that I can not use the laptop.
Any help fixing this would be much appreciated. Thank you.

Press Start and type services.msc
press Enter
Press continue on UAC window
When the services window opens scroll down to superfetch
Right click on it and select Properties
Under Startup Type select Automatic
Under Service Status press Start
Press Apply, Ok
Close the window

Try that to fix the superfetch.

You could also try disabling superfetch service, restart and then reenable it and set it to automatic.

Well I found this as I wasn't sure of whwere this was going Myth Busted: Why Disabling SuperFetch on Vista and Windows 7 Is a Bad Idea » TuneUp Blog about Windows

Now it mentions in the original post #1 an update was interrupted so what about as system restore to before then and redo the update?

You could try the Check for Performance issues troubleshooter in Control Panel
