Creates a per-user virtual upgrade status registry value that will be written to the destination OS, only if the source OS is Windows Vista. If that destination OS is Windows 7, the Sticky Notes tool will read the upgrade value when first started and convert any existing sticky notes to the newer format. Has no effect on Vista to Vista migrations. Used in conjunction with TABLETPCSTICKYNOTES-REPLACEMENT.MAN, which migrates the actual settings (see Sticky Notes 2 ). There is no UI for this setting.
