How to disable the “Get Windows 10” icon in the notification area?

The “Get Windows 10” icon in the tray has been installed as part of the KB3035583 Windows update.

https://support.microsoft.com/en-us/kb/3035583

To remove that icon permanently uninstall this update in the windows software center. The Windows update function might offer this update again in future, so don't forget to hide it in Windows update so that it does not come back.

If you still see the icon after uninstalling and a reboot, then check if there are still files of the update in C:\Windows\System32\GWX. If that's the case, delete this directory.

Enable virtualization on Gigabyte Z77X-UDH3 motherboard BIOS

To enable virtualization on a machine with a Z77X-UDH3 motherboard run the BIOS by hitting Del while booting the computer.

Once inside click on the BIOS Features tab and look for the Intel Virtualization Technology entry. If it's set on Disabled, set it on Enabled. Afterwards save the changes made to your settings and quit the BIOS using the last tab from the main tab-line.

Virtualbox: VT-X is not available

In some cases when you try to get a virtual machine running with Virtualbox or similar virtualization software you will get an error stating that 'VT-X is not available'. This relates to BIOS settings which, depending on your processor, determine whether your computer is able to virtualize stuff. These settings are not set automatically however, so it's worth a look into your BIOS whether you can actually change the setting and if your processor allows it.

The keyword to look for in the settings is 'Virtualization', it's probably placed in some advanced tab if there are some of those in your BIOS.
