Hi, I am at my wits end. Firstly Skype came and went, some days I had it , some days I hadn't , now , despite two copies in the app files , it isn't there as a tile. Then the store, I click on it , it flashes upon the screen , then goes back to being a tile. I click on the cog to look at the pc settings. It takes me back to the tiles. I can't change the settings. I have done the dos commands to re set , all that , I even called msoft and spoke to somebody I could not understand . This is my second surface. The last one died. This is the last chance for this surface before I urinate on it and throw it in the bin.
