I still have the same problem, doing all that in PowerShell didnt really fix anything.
To run PowerShell as admin you can enable it by rightclicking the taskbar then properties, then go the navigation tab and mark the box so you use PowerShell instead of cmd. Now when you right click the starmenu or windows key + x there should be Windows PowerShell (Admin) available. And if you want cmd to be there instead just go into properties again and uncheck the box.
