Hello everyone, I do not often ask in the forum because I find it often, but rapunzel in the forum or in the explanations of moonnique which are very well done, I have a problem for several months when I want to change the icons and the action center icons in c: \ windows \ explorer.exe \ .... When I restart my PC, it starts up and then it spins, but i have black screen, it spins, but I can't do it than a black screen !!!
I have another question for you i think i found it but i am not sure i am looking for the location of windows 10 pro dialog windows in French if anyone could tell me where it is located in the windows, it will be super cool.
