Thanks, Pedro! I found some groups and delete them. Also, I found an option "Start-up Group". If I will use groups, I will check not to use this option. But, may be problem was in this file: C:\Users\User\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\QTTabBar Desktop Extension StartUp.QTTabGroup I delete it, may be it will help.
Hi! Did you find any decision? I've updated Win7 to Win10 and start getting this message.
