A critical bug has appeared with x64 apps &Windows 10 x64. (Not sure exactly when the Windows 10 problem originated, butit definitely is broken in the November Update.) The "My PC" folderin the tree view cannot be expanded, which means that nothing on the C:, D:,etc. drives can be accessed through the tree control. Clicking on "My PC" shows the contentsin the list view window, but the tree/folder view window will not expand it by clicking on the >, double clicking, pressing enter, etc.

Other entries in the tree view (external drives,Libraries, users, control panel, etc.) work as expected. Everything also worksas expected with 32-bit in Windows 10, and with 32-bit or 64-bit inWindows 7.

I thought at first the problem was with my app, but yoursample app "GUI_Explorer" (16.4.0) has the same problem. I triedGUI_Explorer in 17.0.0, but it was even worse -- it won't display anythingat all in the Folder view.

I don't know if this is a Codejock issue or a Windows 10bug, but I've got several thousand users beating on me to come up with a fix.I've been debugging XTPShellTreeBase.cpp and can see that the GetName method isreturning an empty string for the child names of "My PC", but I haven'tyet been able to determine why it happens.

Can you please take a look ASAP and let me know if youhave a fix or workaround?  (If not, I need to switch to an alternative toolkit as quickly as possible, as my appis dead in the water now.)

Thanks for your help.
