Hi Willy2,
ok- I applied tweaks as I see fit and all is good.
I might just say that it might be a bit confusing that, when still working in the first stage / system tweaks, the following 3 are also checked by default. I did not see that - my fault.
So I completely unchecked visual tweaks and a couple of other, single ones and all is good.
Yes - I ALWAYS make a reg. backup, even though with windows, but I guess the tool does as well. I also made a system image before applying the changes (with Macrium Reflect)
I left all visual effects "ON" since I like them and my machine has the resources to handle them and is not slowing down.(16GB Ram, SSD solely for OS)
Actually, the Performance index went even higher from 7.6 to 7.7 - so happy camper.
Thanks for your help and I can highly reommend the tool
Cheers
