or someone can teach me how to make my windows back to 7?
I already updata it over 10 days. it said that i can return to windows7

Firstly make sure your graphics drivers are up-to-date.

Next, try deleting the files located at:

it already up to data
and i dont have " LocalLow "

i use nvidia 441.87
GeForce GTX 1050Ti

When you update Windows via their update tools it generally keeps all your settings. It's odd you don't have that folder.

The only other advice I have, if you're definitely sure your graphics are up-to-date, is to delete the folder where the Cubik exes are and redownload them.

Cubik works fine on Windows 10, so the issue is with your computer, and I can't really give you much more information.

i already try delete all the cubik file and redownload,but it still keep black screen
I will try to make it back to windows 7, thanks.
