I have already JDK 1.6.0.0_25 on my computer with Windows 7 Professional.

How I can savety update current JDK to JDK 7.0 and tesing this update?

I suggest you install JDK 7 as well. You can have Java 6 installed as well and make this this default. You can uninstall one or other version later.

IMO a good way would be to download and install JDK 7 separately. If it works out fine for you, uninstall the previous one and update the environment variables accordingly (namely JAVA_HOME and PATH). You can download the latest stable release here.

Install Java 7. Uninstall Java 6 if it doesn't do that already. If there's an issue with Java 7, uninstall it, reinstall Java 6.

If you're really worried, make a backup. Or try installing it on a VM image of your machine first.
