Anti-virus: Not only do viruses cause harm to your PC, some can even slow it down. So its advantageous to install a good anti-virus and to update it regularly for keeping your computer malware-free. If you're short on cash (which we all are), AVG is a great free anti-virus, but it can't repair infected files.
As Ubuntu users would know, Ubuntu (Like Mac OS) is almost virus-free. But those who still feel insecure, go check this out.
ReadyBoost: If your computer is really low-spec, then one can use an inbuilt service (in Vista and W7) known as ReadyBoost. It borrows memory from external USB devices (pen drive, external HDD) and uses it to speed up your PC. However, if you have a decent RAM (>512 MB), the effect of this tool is negligible. They wouldn’t really need it, but Ubuntu users can also take advantage of this technology. Ubuntu can also create a partition in the hard drive, commonly called the 'Swap'. This area is used as a virtual memory as and when the system needs some extra resources.

Registry: The Windows Registry can be thought of as a log book that keeps a log of all the processes that are taking place, say, installation/uninstallation of programs, changes is system configurations etc. These registry keys can over time become corrupt or redundant and hence need rectification. Software’s like Registry Mechanic can be used to go about these tasks.
WARNING: Making changes in the registry can be dangerous and should only be made if you know 100% about its outcomes. Always back-up your system before making any such changes.
