Windows 10 Tortoise Commit Window Hangs (and Resolution)

Just encountered this issue on multiple dev machines that had been updated to Windows 10 from Windows 8. I wanted to let you know the error and the resolution we encountered in case it helps you, or in case you hear this error from others.

Our situation was that the commit dialog, and other dialogs that displayed file lists, would freeze between displaying the dialog and loading/populating the file list and would be unable to continue. A wait cursor would be displayed until we manually terminated the process.

After looking through previous posts, it seemed that a file icon handler was a likely culprit. With some research, we found that Windows 10, even when asked not to change default programs during install, still changes the default image viewer to it's new Windows Photo Viewer program. This of course changes the icon for image files to this program's icon. The icon handler for this program seems to behave in some unexpected way (perhaps it's own fault) and causes tortoise to freeze whenever it attempts to display an icon for an image file. Therefore all dialogs that included an image in the file list caused an unrecoverable hang.

For us, the solution was just to set a different program as the default program for opening image files (which is what we intended anyway, but the Windows 10 upgrade installer ignored this request). The problem was immediately resolved, although we do need to do this on each dev machine.

I'm not sure if this should or even could be fixed within tortoise, or if this fix needs to come from Microsoft since their Photo Viewer program seems to be responsible. Even if tortoise can't fix this, I hope this helps other users with the same tortoise issue on Windows 10 to resolve it.

We have already resolved this on our dev boxes, but if anyone needs more information from us about this I am happy to try to provide any answers I have or can work out.
