How to Install Windows 10 Technical Preview on Oracle VirtualBox Virtual Machine

I'm enjoy learning a new thing everyday. To learn more about Windows 10, I'm using Oracle VirtualBox Virtual Machine to install. Since VirtualBox 4.3.16 Oracle VM VirtualBox Extension Pack (VirtualBox Guest Addition) not work with Windows 10 yet, I cannot see a full screen and using a shared folder. Hope the next version of VirtualBox will work well with Windows 10

Java Vulnerability

After learning about Java vulnerability from the Department of Homeland Security's United States Computer Emergency Readiness Team (US-CERT), I checked all my browsers in all computers: Ubuntu Linux, Apple Mac OS X, and Microsoft Windows to make sure Java is disabled. To test whether Java is working on my computer, go to this URL http://java.com/en/download/testjava.jsp

Here are the screenshots from my Windows computer:

Java was disable on Google Chrome 23 on Microsoft Windows. Oops. I need to update Google Chrome to the latest version Google Chrome 24. Always keep your browser up to date.

'No working Java was detected on your system.' Good. Java was disabled on Mozilla Firefox 17. Again. I will update Firefox to version 18. On Ubuntu, it was 'Something is wrong. Java is not working'.

Java was disabled on Microsoft Internet Explorer 9.

Next, I went to Control Panel to update Java to the latest version Java 7 update 10 and unchecked the check box 'Enable Java content in the browser'.

 Before clicked the 'Apply' button

After clicked the 'Apply' button

Unchecked the 'Keep temporary files on my computer'

Internet Explorer after unchecked the check box 'Enable Java content in the browser'

Java was disabled on Opera ran on Ubuntu 12.10

Java was disabled on Safari ran on Mac OS X Lion 10.7.5
