You might also want to go into services.msc (via start/run) and disable un-needed windows services.
Do some research first though, as if you turn off the wrong one you could end up w/ a non-bootable computer. If unsure, just google the name of the service.
Regarding the above-mentioned "services", "Windows Search" is a big one. It is constantly indexing the contents of your Hard Drive, eating up resources. By disabling that, searching for a file is slower, but speed of the computer during general operation should improve.
Also, when is the last time you ran Ccleaner?
And lastly, whatever browser you're using, remove all those useless toolbars like bing, ask, google, etc...they are un-needed and only slow your pc down.
