--- Comment #10 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

I think the general consensus was to always use 64-bit regedit in 64-bit
WINEPREFIX to avoid user confusion w.r.t. Wine configuration settings
(overrides etc.). The current restart behaviour is indeed inconsistent.

Let's make this bug report useful and adapt builtin regedit restart behaviour
accordingly.

For an automated import 'reg.exe' should be preferred because that's how most
app/games/installers import registry snippets.

There is bug 44755 which aims support to switch between both views using
'/reg:32' and '/reg:64' command line parameters.

There is also "fun" bug 50308 ("Starting certain Wine builtin apps with
explicit SysWOW64 path in 64-bit WINEPREFIX causes infinite process restart
loop (wineboot, winecfg, ...)") ;-)
