Microsoft Photo Viewer rotate issue

[g3mi 0]

Hi all, 
I installed Endpoint AV v6.6 on PC running Win 7 Pro 64bit

since when I have found that Windows Photo Viewer unable to rotate image on random files with error "Windows Photo Viewer can't save this picture because an unknown error occured"
but that it will sometimes behave normally for 2, 3 or 4 images...

Temporarily disabling protection results that rotate working well on all image.

 

many thanks in advance for your tips....

Does temporarily pausing real-time protection make a difference? It doesn't make much sense to me that an image viewer would save files automatically after rotating an image and that real-lite protection could somehow intervene in this. I'd suggest contacting customer care and creating a support ticket with step-by-step instructions to reproduce the issue enclosed. Also ELC logs as well as a Procmon log from the time of issue replication will be needed.
