Bugs

 * It is currently impossible to upgrade.
 * Sometimes the mouse in WinPE will be disabled.
 * The theming service can malfunction.
 * While using MILExplorer you may ecounter these bugs:
 * When using any visual style (except Windows Classic), that explorer window doesn't show up.
 * When using Windows Classic, opening that explorer window causes an  restart.
 * Aero and DWM are extremely unstable and can cause the following issues:
 * Performance might suffer greatly when DWM is running, even on fast computers.
 * Sometimes, the Aero Explorer may display the text overlapped.
 * TWIWMTB Aero theme is rendered incorrectly, leaving the bottom part without a frame when maximized.
 * This theme is incorrectly scaled when using a Windows Classic color scheme with large fonts and Aero.
 * Upon choosing a wallpaper, the desktop will glitch out if Aero is on.
 * Windows Media Player 9's automatic hiding of the system frame does not work with Aero. The user will not be able to open or close the player or click on any menu until the user presses CTRL+M key to show menu bar and then reopen Windows Media Player.
 * If the sidebar is disabled, the taskbar is not transparent.
 * The title bar text will not update when under normal use in the Aero theme unless you maximize or restore down the window.
 * The Basket sidebar tile leads to an Explorer crash loop if Aero is enabled. The only solution is to remove the tile from the registry.
 * Using Aero increases the chance of Explorer crashing under normal use. There is a chance that Explorer won't load properly and instead the system would suffer tremendous lag requiring the user to hard reset the machine.
 * Sometimes, folders can't be creating using the "New" entry. You may try to use the  /   command or to fix the registry.
 * There are massive memory leaks, usually caused by  and WinFS.
 * If WinFS is not running, you won't be able to open Outlook Express.
 * may crash in a loop in Safe Mode. To fix this, use  to disable Sidebar, which causes this issue.
