I recently upgraded from Windows 7 Ultimate to Windows 10 pro. Every file and folder is now read only. When I click on a folder's property and uncheck read only and tell it to make the changes to all sub folders and files it says access denied and that I have to click continue as administrator to complete the action. I am the administrator and do so, but it doesn't work. So, how do I fix this? (Also, the read only box is that square looking mark, not the check mark if that is relevant). Edit: Also, less important but for some reason many of my live tiles are grey. They are still usable, but grey instead of the colors that they should be. And my lock screen is grey instead of showing the picture like it is supposed to.
