Thanks for all your help and replies. MS-support helped me out with remote control. It turned out that my login profile was somehow corrupted and I had to create new one. Case Solved

Unfortunately it doesn't matter which tiles you move first :(

Thank you for tips, but I still cant move those tiles to left. And I have plenty of tiles so that's not the problem. Here's video: https://www.youtube.com/watch?v=hKWQMPPuqao&feature=youtu.be

I have very annoying problem with the start menu. When I expand the menu horizontally, the tiles wont move in to the empty space. I have tried everything. Cant move them manually either by dragging....
