Open each folder in the same window" not working

I'm not sure if this will help, but you can try:

    1.Click Start, and then type cmd in the Start Search box.

    2. Right-click cmd in the Programs list, and then click Run as administrator.

    3.If you are prompted for an administrator password or confirmation, type your password or click Continue

    4.At the command prompt, type the following line, and then press ENTER: sfc /scannow

    When the scan is complete, test to see whether the issue that you are experiencing is resolved.

If that link breaks or you just want a quick and dirty answer:

From a command-line prompt with admin privileges run these commands:

Then reboot your computer
