When I'm in any app and hit the file tab in my fully updated Win 10 Pro, as soon as file explorer opens all of my desktop icons switch to the blank dog eared white rectangle and immediately back again. This only happens the first time I try it within the app. If I try to open the file browser a second time in the app, the icons stay stable. If I open a shortcut on my desktop to a folder, the icons stay stable. I've posted this on a bunch of different forums and gotten a lot of conflicting answers. Microsoft support spent 3 hours with me on the phone and couldn't figure it out. HP spent a lot of time updating drivers, etc and my preboot diag is clean. It also happens on another box I have but to a much lesser degree and stops after the first few times so I don't think it's hardware related as that system is completely different, soup to nuts.
Any help would be great. Thanks. Oh, and this windows was just installed Wednesday.
