How to reset "Remaining Windows rearm count"?

I have build my Windows 7 Enterprise reference image but unfortunately did sysprep multiple times so therefore now remaining Windows rearm count are left 0 and I know, if I run sysprep, it will ruin the whole image.

I have spent many hours on my reference image, I can't rebuild it?

Is there any way to reset this count?
