Hi, StefVR1!
My name is Caio. I'm an Independent Advisor and I'll be glad to help you today.
This program is nothing more than one of hundreds of similar programs that promise to improve Windows performance in a very advanced or surprising way, but that end up doing nothing beyond what can already be done natively by Windows and can still damage your computer.
It is worth mentioning that, in addition to the low cost benefit, they can also end up damaging the computer with changes in the registry that of them some make.
Here's a free (and ad-free) guide on how to improve your Windows 10 performance: https://support.microsoft.com/en-us/windows/tip...
You can also perform a reset, keeping your personal data, to make your Windows cleaner (also for free) https://support.microsoft.com/en-us/windows/how...
I hope this helps you! Please let me know if I can assist you more.
Best regards,
Caio G.
