For a faster boot up enter your Bios, by clicking the Delete, F2, or F12 key or whatever flashes on the screen when you turn on the computer. Next choose boot order, and remove all entries except the first one which you should set to your hard drive.
This will stop the most of the time useless seeking of a floppy disk at boot time. If you need to reinstall Windows or some other operation, you can always go back and change this entry to floppy or CD. Also there should be a setting in your BIOS to make the boot, quick.
Patch Your Computer To Keep It Updated Go to Windows update on the top of your start menu and download all the patches for your operating system, whether they are optional or critical.
Better yet, go into the Control Panel, choose Automatic Updates, Choose Automatic (your screen might look different with a different version of Windows). Make it Every Day at a time when you are not using your computer.
Generally if you have cable or DSL, despite the risk of infection, computers should be kept on and attached to the Internet. This is to allow antivirus and security patches downloading at off-peak hours.Link to Original Source
