Microsoft works constantly to release updates to Windows and other Microsoft products, including Office. At Microsoft Update, you can find and install all these updates—not just the critical ones. Often, these updates will improve your computer's performance.
You can make life easier by automating Microsoft Update so your computer downloads and installs all the updates without you having to worry about them.
To automate Microsoft Update:
In your Start menu, click Control Panel.
In the Automatic Updates dialog box, check the Automatic (Recommended) check box. You can define the time of day when your computer checks for updates. If the computer finds any updates, it will download and install them automatically for you.
Automate Microsoft Update to keep your computer up to date.
Install antivirus and antispyware programs
Computer viruses and spyware (hidden software that gathers information about you without your knowledge or consent when you're using a computer) both reduce system performance. Computer viruses can not only reduce performance, but they can also destroy data. Any computer that accesses the Internet should have antivirus and antispyware programs installed.
Follow these steps and you'll have your computer purring like a vintage Porsche (or whatever your dream car of choice is). And the best part? Maintaining your computer is a lot less messy than an automobile. You don't even have to roll up your sleeves
