Ok thanks both for the answer!
@LightStar, about the start bar, as i said, i prefer using Classic Shell, since it allows more manipulation. As an article sais:
For example, in Classic Shell I can drag and drop a program, moving it from one folder to another. Start10 doesn’t have that ability. In Classic Shell, I can right-click on a folder and create a new folder. Start10 can’t do that, either.
More than anything, in Classic Shell I can move a program from, say, the bottom of a folder’s list to the top -- very important with Word in the Microsoft Office folder, for example, which deserves to be near the top of the folder, instead of squirreled away at the bottom. In Start10, you can’t reorder items by drag and drop.
and i feel really comfortable with Classic Shell's way to do.
