To root Andy download this rootkit, extract the archive and run AndyRootkit30.exe. It comes with frequently installed root applications that can be installed in the process and also allows unrooting Andy.
Pro Easy to get started
As long as virtualization is enabled in BIOS, the setup is straightforward. Simply download, install, run. First time the software runs it will ask to either log in with a Google account or create one allowing it to download software directly from the Play Store.

Pro The virtual machine Andy runs in is highly customizable
With some tinkering, Andy can be set up to run with up to 3GB of RAM, the current Android 32bit RAM limit. It allows for a smooth experience and offers enough power to have multiple apps running simultaneously. The VM can even add more virtual CPU cores to Andy, doubling it's processing power or more.
Pro Use of Genymotion VHD allows Andy to be very fast
Andy is built on top of the powerful Genymotion VHD. It takes advantage of OpenGL capable graphics cards allowing it to be one of the fastest Android emulators.

Andy comes with a custom clever implementation of ADW. It is theme-able, while functions very well without any modifications. The app sorting is a nice touch. Andy is compatible with most Android launchers.

Pro Great application compatibility and stability

Pro Great Clash of Clans gameplay experience
The new launcher provided for, it seems, limitless number of Andy tablets. Have a Andy just for CoC with 3GB and 4CPUs to maximize your CoC play to the next level. Then make a full copy of that machine for a full backup. Have an Andy for the children, be able to lock each Andy with a password lock-screen. And manage all this with less only 7 buttons ;) Again, Simple and powerful.

Andy's Installer has been reported to drop a bitcoin miner on users computer which causes significant drop in PC performance.

KitKat version is planned.

Which is where windows is installed. What's more, it does not let you change the installation path.
Con Quite resource intensive

From my experience, TeraCopy does not do well in conjunction with 7zips.
It seems to error on some systems when you do a drag-and-drop extract.
