Microsoft launched windows 10 as a game changer and almost different from earlier operating systems. It came out to rectify the flaws from older os. For example windows 8 application accessibility from start panel was kind of a mistake. Window 10 gives easy accessibility in beautiful manner. Windows 10 has beautiful and attractive user interface. But with its goodness it has s several issues. I used to run my projector on windows 7 without any issues but after upgradation to windows 10 I can not run it any more. Windows 10 doesn’t detect my projector. There is issue on alt + tab when u switch between window explorer and any browser then all opened window folders gets closed automatically. Another one is it ducks the laptop battery quickly.
