I'm not certain you really mean "window comparator".Make a sketch of what you want, please.
Go google about synchronous rectification if meaning high efficiency power rectification or precision rectifier if you need a signal itself.https://en.wikipedia.org/wiki/Active_rectificationhttps://en.wikipedia.org/wiki/Precision_rectifierAs of what you described is weird. And comparator has only 2 states on it's output, what linear signal?
Am I wronh in thinking that this circuit: https://upload.wikimedia.org/wikipedia/commons/c/ca/Op-Amp_Precision_Rectifier_%28Improved%29.svgonly is a half-bridge rectifier?And combined with the comparator, it gets to be a full bridge rectifier?Hmm does it not loose a lot power in that configuration?
I have only seen something that is called window comparator, where it detects if peak voltage is above or below trigger voltage and have that voltage stored
So my thought was to let the "window" be configured so that it only triggers with max voltage i.e. 5V and send these 5V to the opamp.
Your opamps have no part number and no power supply voltage so they will not work.The second opamp has positive feedback so if there is a tiny positive input to it then its output will go as high as it can and stay like that (even if the input signal stops) until the power supply is turned off.I guess the supply is +15V and the opamp is "rail to rail" allowing its output to go as high as +15V.

Add another diode and opamp and you will have full wave rectifier.
