Windows 10: Windows 10 photo viewer slowing down

Hello

A while ago i downloaded IrfanView and since then the default windows photo viewer takes a very long time to open my pictures and even if it does open, it will open with a white screen which means nothing will happen or it will open with black which means it will take a bit. I only used Irfan to open some files that windows couldnt, I dont remember setting it to default nor anything among those lines. If i delete Irfan will it fix my issue, or is it something else?
Thanks for reading.

:)

 

Windows 10 Photo Viewer - SLOW - SLOW - SLOW

My Windows 10 (and Windows Photo Viewer) was running fine for the past 10 months until the late Sept 2016 updates. Then "poof" - welcome to SLOW, SLOW Photo Viewer. Thanks Windows 10 update. Several people have suggested fixes in the registry under:

HKEY_CURRENT_USER\Software\Microsoft\Windows Photo Viewer\Viewer

or

HKEY_CURRENT_USER\Software\Microsoft\Windows Live\ Photo Viewer\Viewer

The problem is that I have NO folder named "Windows Photo Viewer" or "Windows Live" or their sub-folders. So I have to assume that the Windows 10 update wiped them out.

So I can tinker with the registry (risky) or find another default photo viewer. Or maybe it is time to become an Apple user.

 

How to get rid of raw file support in windows photo viewer?




I have downloaded this, and it did not work; photo viewer is not in the list of programs in Open With or Default App. I used option 2 step 3, followed by step 5 to 9.

 

Replacement for photo viewer

Win ver 19041.388

Just do not like this "new" photo viewer, it is just cumbersome to operate, lot of extra steps etc. I like the older Win photo viewer, however since JPG files are saved as "unhandled Extension handler finder", *Confused I need something else. Appreciate any suggestions that is not overly optioned, just a simple viewer. Tx
