I'd recommend CCleaner:

CCleaner is a freeware system optimization, privacy and cleaning tool. It removes unused files from your system - allowing Windows to run faster and freeing up valuable hard disk space. It also cleans traces of your online activities such as your Internet history. Additionally it contains a fully featured registry cleaner.

While CCleaner that Sathya mentions is good for cleaning up trash and such, I think you will get the most space from uninstalling software packages you no longer use (Photoshop for home use anyone?) and throwing away large, unused files.

I would recommend TreeSize (or anything similar) to help you detect sometimes very large files hidden deep within your system, which you have long since forgotten about. It will also tell you which applications take up way too much space, so you could consider uninstalling!

Every hard disk is too small if you just wait long enough. TreeSize Free tells you where precious space has gone to. TreeSize Free can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. You can expand this folder in Explorer-like style and you will see the size of every subfolder. Scanning is done in a thread, so you can already see results while TreeSize Free is working. The space, which is wasted by the file system, can be displayed and the results can be printed in a report.

CCleaner is the best, plus with the command lines, you can have it scheduled to automatically keep your PC clean. This is what I do, I believe in automation of maintenance...
