Creates tiles for any Windows 8.1 (Largely untested) and Windows 10 (Build 10586 and above) Start Menu icon.

Features:

Allows creation of Medium and Small tiles for your applications, modifying their current shortcut where possible.
Create custom shortcuts to Steam games, Chrome apps, Windows Store apps and explorer shortcuts, or any other shortcut target you wish using custom VBS script launchers.
Extract icons from the software EXE/DLL, without using any other external program.
Move and resize the image to where you want it within the tile, allowing more customisation than simply a full sized image.
Supported Languages: English, Russian (happy to add other languages if anyone can help with translation).

Basic tile creation usage:

Find the shortcut you wish to modify in the list
Choose an image by clicking the 'Change Image' button or double clicking one of the logo boxes. Move/resize it as required by clicking, dragging and scrolling to where required.
Hit 'Tile Iconify!' to apply the changes
To restore, hit 'Remove Iconify'
Custom shortcut creation:

Navigate to Utilities -> Custom Shortcut Manager
From here you can create a new shortcut or delete other custom created items
When creating a new shortcut, it will take a moment to populate your Steam, Chrome and Windows Store libraries.
Most items will get a default icon based on what you choose. At this stage, you can change the icon to what you want.
Choose the shortcut name and which users it should be available to.
Generate the shortcut item. It will be Iconified using the icon chosen, but you can amend this as required back in the main page.
Finally, navigate through your Start Menu to 'All Apps' -> 'TileIconify'. From here, you can pin your new shortcuts to your Start Menu
