========================================================================== In the folder C:\Program Files\Dell\SupportAssistAgent\bin\Resources\  rename New-Dell-Logo-White-Small.png to  New-Dell-Logo-White.png (just remove the -Small from the end of the file name) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ THIS WORKS!! Found this solution here. Spread the word!

I still get the notification to run support assist, but when I do it pops up the window and stops responding right away.  You can see a screenshot here: [URL]
