Securing Windows

MS Windows has come a long way in terms of security. When it comes to Personal computers’ Operating System (OS), Windows (Windows XP, Vistas and Windows 7 put together) accounts for nearly 90 % according to the statistics published in W3Schools. The statistics for March,2011 show that Windows 7 has 34.1 %, Vista has 7.9 % while Windows XP has 42.9% of share. For the curious, Linux has just about 5.1% share whereas Mac has 8% at the same period.

Microsoft has worked hard on its latest avatar of Windows to make it not only more user friendly but also a lot more secure than other versions of windows. It offers an effective anti virus software – MS Security Essentials and a Malicious Sofware Removal tool too.

Windows 7 also offers a better firewall with complex inbound/outbound configurable ruleset. In other words, MS offers – better security straight out of the box than before. With that said, it still pays to be prudent and follow the suggested steps to enhance the security of your Windows computer. Windows 7 Firewall

1. Enable internal Firewall.
2. Set up ‘hard’ passwords for all accounts. In older Windows set up password for all accounts. Disable guest account while you are there.
3. Keep your patches and hot fixes current. This is not just for the OS alone – but also to your browsers and Email clients.
4. Disable Remote Desktop until you need it. When you are done, disable it promptly.
5. Create backup in an external device.
