Lightroom 6.7 extremly slow after last WIN 10 update

Hello!

I already noticed this was the issue in the past, but can't find solution for it.

I have LR 6.7 with Camera raw 9.7 and until yesterday everything worked perfect. LR was fast, no lag in between operations, nothing strange.

Yesterday I updated WIN 10 pro to newest build, so now I have Version 1703 and build 15063.413. And with this update, everything changed. Lightroom became slow as hell, can't work normally. There is lag between operations, when I copy/paste, it takes time....

I did not change anything anywhere, just updated windows. And now this.

Is there any known solution to this? Otherwise I am seriously thinking to go to alternative.
