Sorry, I don't know what happened!!!All my purchased Stardock products are on my personal laptop only. My son is now gone off to school and has a new desktop computer and I plan on taking over his old one. I'd like to put my software on his old desktop and I know that's allowed as long as only one system is used at a time. I plan on keeping his stuff on it so that he can play his games and go on the internet when he's visiting. I have two questions... Can I have Windowblinds and other programs installed and only used and seen by one user (me) and when he signs in to his, he only sees Windows XP and none of the customization that I use? And if he's visiting and using the desktop signed into his while I'm on my laptop, is that still kosher as far as licensing goes?
