1°) Cool to see that lots of things are done for XP ... 
2°) not speaking about features but updating: if by any chance, WindowBlinds is running when you update, at he next boot there's systematicly an error message that "WindowBlinds is missing a core dll file WBLIN.DLL. Please reinstall WindowBlinds"
As Impulse is not proposing to download and archive the new version (like SDC did), the only way to do it, is to go back to re install previous version, then to don't get the same error message, unable WindowBlinds to start with Windows by activating "Windows Classic", then reboot, then update, then reboot again ... With the time needed by Impulse to load and verify everything's, the update has taken about ½ hour for me
. Should it be possible to fix that ? (it's not a trouble relative to the last version, it's something which came with Impulse ...)
3°) SDC gave the opportunity to "Prompt to select where Start Menu shortcuts are created" . It would be a minimum that impulse would do the same ... (not specific to WindowBlinds but to any of apps)
