Steps to reproduce

URL:

Repro Steps:

Enable group policy at User Configuration -> Administrative Templates -> Windows Components -> Windows Explorer -> Disable Known Folders.
Start Internet Explorer, then observe the contents of C:\ and a new folder ought to appear.

Expected Results:

Obviously IE should not be trying to create paths based on uninitialized memory.
The group policy documentation states that disabling known folders can lead to compatibility issues with applications which assume that known folders are available, but that doesn’t mean such mistakes shouldn’t be fixed.

Actual Results:

Dev Channel specific:

No
