Question Floating window of performance stats

[sargan]

In past week a floating transparent window has arrived on my desktop , giving real-time information on my PC hardware
I do not know what program is generating it ... there seems no option to close or move it
Anybody know what creates this (or how to remove it):

Do you have an application like GPU Tweak installed?
