I got this problem after using the same installation of win10 for a long time. I think it was around summer/late Summer. The problem is I can't open programs after ive searched in the menu. Ex: i press Windows key and then Type paint to open mspaint. But it wont start. So instead i have to press Windows+R and Type mspaint for it to start. Very annoying in the Long run.
Ive tried searching Google. But i didnt fond a Good solution.
