This machine was for a relative who is not PC savvy.
She has had it a while now & everything has been fine, she has the desktop, start menu with no problem
She switched the laptop on a few hours ago & once loaded this window appeared on the desktop.

Her desktop is there but it is blanketed by what looks like a configuration file for skip metro suite. Ignore the small dialogue box, that was me taking a snapshot through team viewer.
The red close tab is not active & therefore will not close, right clicking on the task bar to close that window, that is not active either.
The only solution I found was for her to go into task manager & kill that window which worked.
Restarting her machine the window appeared yet again.
Can anyone help me please, I don't have Windows 8 so I cannot replicate the problem.
Thank you
