Even if someone chose not to user Windowblinds skins, WB 5's wallpaper changeover would be worth product's price. It produces near instantaneous changes, while the Windows XP mechanism using the Display control panel and the StyleXP mechanism, which seems to depend on the Windows mechanism. The Windowblinds 5 wallpaper function also lets the user access all the locations where wallpaper is stored, unlike the Windows mechanism that accesses only one location and the StyleXP approach which loses all differentiation between the different locations. Its sheer speed, however, is the real killer feature.
(Users should note, though, that if they want to change wallpaper and make no other changes, the fast way to do this is to select the wallpaper and double click it. Using the Save Changes command results in a more time-consuming refresh of the visual style.)
