I use Coowon browser. I was running Windows 8.1 Pro and downloaded Windows 10 when it was offered to me for free. It worked for about a week and now when I left click on the Start Menu Window in the lower left of my task bar nothing happens. If I right click I do get a very basic list, and I mean basic. No programs just things like task manager, run, search (that will not open), programs and features, etc. Also there are other icons on my task bar that do not work. I no longer have the Windows 8.1 desktop menu or the ability to swipe in that mini menu from the right side. My system does say I have Windows 10, but I have none of the features. Can anyone tell me how to fix this please. I tried to call MS and after being on hold for 4 hours I gave up. Thank you.
