Through your normal means (Add/Remove Programs), uninstall the following if you can:

WeatherBug
SuperRam
Askbar
Yahoo! Toolbar


You don't have to remove the last two if you don't want to. But I personally don't find much use for them and they usually install as part of some other software.

If you don't share any Apple equipment, like AppleTV and such, then you can get rid of Bonjour. iPods will still work for syncing. You can also get rid of Google Update.

I wouldn't bother with any RAM management programs like SuperRam. In my experience, those things tend to do more harm than good. Windows is pretty good about dealing with RAM on it's own.

As DemonBob asked, I would also like to know your PC's specs. Also, after you're done cleaning things up (run CCleaner too), run a defrag of your hard drive.
