Windows 7 explorer refuses to open files in the same window

[UnworthyBean]

I've tried googling this to no avail, All the fixes seem to do nothing. And yes, I have the correct option ticked in folder options

Also ran Malware bytes and it found nothing, 'SFC /Scannow' also didn't do anything.

Anyone got any ideas?

Yeah, thought the same and tried every fix on the first page of google, Nothing worked and a couple broke it even further.

Just had to do a repair install, fixed it but was a pain.
