Q7 is for Windows 7 only. There are no substyles for Vista or XP.
Unfortunately this will most likely be my last submission to DeviantArt due to health reasons that have developed over the past 6 months. I have been working on another skin inspired by this one but have doubts about being able to finish it. But I will do my best.
In any case I want to thank all the members here that have faved any of my work and/or left such wonderful comments. It's nice to know that with all the fantastic art on this site that even a mediocre icon maker can acquire a few fans. Thanks for that.
