Thank you.

Windows Home vista 32 premium
Hey Stella-50,
How slow is slow? For example, my machine (e-machine E4264 2.2 ghz with 2 GB RAM) boots in 95 seconds. For me, I call it, in the average. I am currently in the process of looking for a new machine because it is already 3 years old, so maybe that OEN will be slightly faster to start.
What you can 'turn off' will depend on which in fact initially launches upward and, unfortunately, you have not told us that at this moment. Is that you should not disable your anti software anti-virus (updater). nothing to do with your mouse and your keyboard etc.
Perhaps, if you made a list of what application are actually being run at startup (via the msconfig Startup tab) can someone take a look at them and see if, or what can be disabled.
Otherwise, you might take a glance at Startup Delayer http://www.r2.com.au/software.php?page=2&show=startdelay to see if you can delay the time different applications load to allow windows to start up more quickly. I haven't used so I can't say how good/bad it is. It's a freeware.
