Windows 7: picture viewer is insanley slow

seperated to own thread from - Windows Photo Viewer is insanely SLOW!

Ok old thread but hey at least I search!

I have the same problem, picture viewer is insanley slow. I followed these steps but under my default profiles there are none to "remove". I use a Nvidia 9800gt video card if that has anything to do with it.
Whats weird in my problem it seems to be only the photos I've been scanning from my printer that open slow. I'm doing them at max quality and they're bigger files...about 600mb some of them. Maybe being that big it wouldn't matter what viewer I use. Smaller files open up nice and fast though.

Welcome to Seven Forums qwiksilvertrav. I suspect the enormous size of the pix files is causing them to open slowly since smaller ones open fine. That is a lot of data to bring together and display. Make sure you have Windows' defrag set to run automatically.
