First step is always to do it within the realms of your computer, meaning no internet usage.
You should first close running background applications (see taskbar). Currently, the only 3rd party software running on my Vista is AVG Free Edition Anti-virus software. That's it.
Next, you should try deleting prefetch (its like refreshing Vista). Go to My Computer > C: > Windows > Prefetch. Delete all the files except for the folder. Confirm deleting. Some files may pop-back instantly, that's fine. You don't have to delete it again and again.
Now empty the contents of the folder in Prefetch.
Next, you should right click on your drive letter (e.g C:) and properties. Then use Disk Cleanup. Select all the boxes and then on OK. You can free hundreds of megabytes just by doing so.
Next is a step that some strongly do not believe is necessary. But I do believe. Vista may defragment your drive automatically, but its best to do it yourself. Just like the above step. Right-click on your drive letter and then on Properties. Then on Tools > Defragmenter.
Next is a step that I have done before, but due to overcomplications of which one to turn off, you can definitely go here:
