1. Open winecfg
2. Select Windows 7
3. OK to close
4. Open winecfg

2008R2 is selected.

The problem appears to be that winecfg is pulling the build version from the
registry - but different versions of Windows can use the same kernel and hence
have the same build number (such as 7 and 2008R2).

build_str = get_reg_key( HKEY_LOCAL_MACHINE, szKeyNT, "CurrentBuildNumber",
NULL );

isn't enough information for winecfg to know which version you selected last
time.

A +winecfg trace shows this happening.

This has only become obvious now 2008R2 has been added, but XP x64 SP2 and 2008
SP2 will suffer the same fate (when added).

What I can make out from the code it seems to store szVersion but doesn't
retrieve it.  Obviously, I have no idea how to fix it or I would have sent a
patch.
