1 Install and use CCleaner (Crap Cleaner-it deletes cookies and browsing history, temp files etc, and is also an excellent light registry cleaner) - run it daily or so. Free Version 2.Have a look at what items are in your start menu - many can be deleted. Look up Start Menu in Google.3. Others will add more suggestions. I assume you have anti malware scanners and use them. I like free Superantispyware and Malawarebytes, plus Spywareblaster to try to stop malware.
