Switched PC on this morning and got to the main windows tiled screen but then the screen has just frozen. I can't use any of the on screen commands using the mouse and the only thing I can get is the options from pressing ctrl alt delete. I've tried shutting down and restarting and leaving the PC for a couple of hours but no change?
Does the mouse cursor work in the Start screen? If it does try hovering over the desktop app then press the Windows key then left click. See if you can get to the desktop. There's a weather app that causes this, I've read, can't remember the name but remember it starts with 'A' I think.
In the desktop right click the task bar and select task manager. Select File, then Run New Task. Type cmd and check the box to give admin privilege. In the command prompt type sfc /scannow and let it run. See if it corrects some errors. You might need to run it a few times. See if that helps.
