When moving an item to the recycle bin in older versions of Windows you were asked to confirm that step - this dialog was removed in Windows 8 but can be brought back with a simple tweak:

Hibernation is disabled on Ubuntu 12.04 and Mint 13 by default - you can only access it with the command line. To have it as an option in the shutdown menu again, open a terminal and enter the following:
sudo gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
By that you create a new text file. Paste the following into it:
Save the file afterwards and reboot. Hibernation should now be an option in the shutdown menu again.
One of the more useful Aero features of Windows 7 was that you could just hover your mouse over the bottom right corner where the Peek rectangle was positioned and all the windows would become fully transparent so you had a better overview of the desktop.
In the Windows 8 Consumer Preview the only default option to do this is to right-click the taskbar and to select Show the desktop - which is done with two clicks more than before.
To save those two clicks there is an easy way to re-enable Peek preview by right-clicking the space in the bottom right corner where the rectangle used to be and to activate Peek at desktop.
The space will then have the same functions as in Windows 7. If you move the mouse to the very corner however, it will still trigger the Windows 8 Charms menu.
Enabling USB Support in Virtualbox means to be able to access USB drives plugged into your physical machine on your virtual machines. To accomplish this, you first need to download the newest version of Virtualbox (4.1.8 at the time of this writing), which is not available in the Ubuntu repositories but on the Virtualbox homepage:
Uninstall any previously installed version if present and then install the downloaded Debian package with a package installer taking care of dependencies, such as gdebi.
Next, head back to the homepage and install the Virtualbox Extension pack which supports USB 2.0.
Now you have to make yourself member of the vboxusers group. Go to the Users and Groups Settings in your Control Panel and hit Manage Groups. Scroll down to the vboxusers group and hit Properties. Check the box next to your username and click OK.
Last but not least you have to enable USB for the virtual machine. Close it if it is running and enter the Settings window. On the left panel, select USB. Check Enable USB Controller as well as Enable USB 2.0 (EHCI) Controller. Then click the button with the small green plus-symbol and add the USB device you need:
If you run the machine a USB symbol will indicate that USB is enabled and a device is running on virtual machine:
