File browser differences

I have an application (VideoReDo) that requires an older Windows version for
its file browser to work correctly.  When I install the prefix I set it to
WinXP.  Newer versions cause problems when trying to create project files
(possibly another bug).

Since v8 was released, every update that's been released in the devel tree
keeps resetting the prefix back to Win10, forcing me to go in to winecfg to
reset it back to WinXP.

I can understand setting new prefixes to Win10, but wine should not be
overriding OS version settings for an existing prefix when a new update is
installed.

From the attached image you will see the WinXP file browser on the left and the
Win10 (or any other version newer than XP) on the right, along with the error
that occurs when trying to save a project file on non XP versions.
