Perhaps the easiest way to tell whether or not you need Java is to first disable it entirely. If you regularly use an application or visit a Web site that requires Java, your system or the site will prompt you that you need to install or re-enable Java. You may find that you don't need it and don't miss it. On the other hand, if you do use applications that require Java — such as programs in the Adobe Creative Suite like Photoshop, Illustrator or InDesign — "responsible" use of Java will let you use them without putting your computer at risk.
First, always keep Java up to date. Whenever you're prompted to update it, install the patch as soon as possible. The smallest delay can expose you to malware. Second, set aside one browser for websites that absolutely require Java, and disable the Java plug-in on all other browsers. Use the other browsers for everything else, for example checking your email or reading the news.
This way, if you land on a compromised website that's trying to exploit a Java flaw, odds are you'll be protected.

Some people have reported that the User Account Control feature gets in the way of installing Java. If you suspect that the User Account Control feature is causing your problem, you can temporarily disable it until after the installation is complete. The method for doing so depends on the version of Windows you're using.
If Internet Explorer is configured to use a higher-than-default security level or if it is running a custom security level, there is a possibility that Java may be blocked. You can set Internet Explorer to the default security level by opening your browser and selecting the Internet Options command from the Tools menu. When the Internet Options dialog box appears, click on the Security tab and click the Default Level button. Click OK to save your changes.
