Surface Pro 2017, Win 10 Pro x64: Explorer crash (Windows.UI.XamlHost.dll)

And wait! I am listing what I can see from the crash dump below and it notes DropBox but I uninstalled it!!! How is this possible. I am really starting to dislike Windows 10 (and perhaps the Surface).

Check the location and see if the DropboxExt64.19.0.dll is there:

Nope. I put a screenshot below of the remaining DropBox folder: the Update folder is empty.

I have not rebooted since uninstalling so maybe somehow Dropbox is lingering.

I also just had an explorer crash and no crash dump was created. I think this one might have been a more serious one: the machine was on battery and in hibernation, when I turned it on for some reason it shifted from landscape to tablet (portrait mode) despite the Microsoft keyboard never being unattached. I am getting some Event Id 17 (local blue tooth adapter has failed for an undetermined manner) errors in the Event Viewer, though I think I get these pretty regularly. I will be shutting it down and seeing what I get after.

Seems like you've done everything but still keeps crashing. Make sure you have backed up all your files to avoid losing your important files. Try resetting your windows. here is the link from their website https://support.microsoft.com/en-us/help/12415/windows-10-recovery-options
