Thank you so much for all this info. I have a Dell Inspiron N5110 laptop, and have been getting this pop up for days now. The DSD is followed by 4-digit numbers (today it was DSD_3002). I thought maybe I had deleted a program that was used by an existing program. But I went into my Programs and Features like you instructed, and choose uninstall. It gave me an option to fix it, but I chose an uninstall. I look forward to my next boot up, to see if it's gone. Thanks so much. I'm glad I selected the first entry that came up when I searched for this problem on Bing!
