Bugs and quirks[edit | edit source]

Aero Lite transparency effects[edit | edit source]

When using the Windows Basic (Aero Lite) visual style, transparency effects can be enabled by means of a bug in the Personalization Control Panel (don't persist if you re-selected the theme created). To do so:

  1. Right-click the desktop and open up Personalization, then click on the "Window Color" link given at the bottom of the window. Keep the window open.
  2. Open a separate personalization window and apply the Windows Basic theme.
  3. Switch to the other personalization window that was opened at the start, uncheck and re-check the "Enable transparency" option and then click on the "Save changes" button. This will cause transparency effects to take effect.
