[PATCH 0/1] MR6667: explorer: Support the NoDesktop registry setting.

[Alex Henrie (＠alexhenrie)]

Setting NoDesktop to a nonzero value hides all desktop icons on Windows.
(It also disables the context menu on the desktop, but since Wine
doesn't have one, that doesn't matter.) Supporting the same option on
Wine would be useful in controlled environments that have a virtual
desktop but the user is not supposed to interact with it.

Strangely, although HKCU overrides HKLM for NoTrayItemsDisplay on
Windows, the reverse is true of NoDesktop.

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:
