[@Gioantonnello] They want us to try out the program and are generous enough to not stop it from functioning after 30 or 90 days or even a year. They want us to tell our friends if we like it. If we grow to depend on it, then they hope we will purchase an upgrade or lifetime license once new features are added that we want, or once Windows changes enough that our old version quits working, or once our HDD or SSD fails. They can get more sales, we get something helpful. Good deal for everyone.
And yes, Windows lets you control what starts, but it’s not so helpful in finding which programs delay startup the most, or having some start on after a delay (so you can get other work started sooner). BootRacer does these things well. I have been fortunate to get a new version free on SOS several times now. Thank you SOS and BootRacer team!
