Microsoft Windows XP support ends: How to update? If you’re still running Windows XP — what do you do now? This doesn’t mean that computers running the operating system will stop working, but it is likely that the computer will be attacked by hackers as the company stops providing security-updates and technical support for Windows XP.

Generally speaking, you have two new choices: Buy a new computer or update to Windows 7 or Windows 8.1. If you’re not ready to make a change, there are things you should do if you’ll still be on XP over the next couple of months.

Firstly, make sure the software you have is as up-to-date as possible. That means having any security fixes you can’t get from Microsoft’s website and make sure that you’ve got some (non-Microsoft) antivirus software installed(安装) from other websites. Of course, if you want to keep really safe then you’d better stay off the web altogether, though for many users this won’t even be a choice. Another choice is to change from using an administrator account to a limited account for tasks, like checking your e-mail. This means that if a hacker attacks your computer, at least they won’t have administrator-level access.

However, we have to stress that these steps are just temporary(临时的) measures and aren’t enough to protect your computer in the long run. Whether you’re buying a new computer or simply updating your present operating system depends on yourself. You’ll have to choose between Windows 7 and Windows 8.1. Whichever you go for, you’ll need to check that your computer meets the minimum system requirements for either system. For either Windows 7 or 8.1, you’ll need at least a computer with 1GB of RAM, 1GHz processor and 160GB of hard disk space. However, to run a better operating system, you’ll need a computer with over 4GB of RAM, a 2GHZ processor and 500GB of hard disk space. Buying a new computer with these functions, you may pay more than＄500.

If you’re still planning on updating, Microsoft offers some great guides on their own website, meaning that you can download your new operating system and copy all your old files without leaving your computer. Windows 7 is certainly better than Windows XP, but you should be aware that it is also an ‘old’ operating system. Microsoft Company will add more updates to Windows 8.1 over time, while Windows 7 will also come to an end before long — just like XP.
