[Bug 10040] New: Steam crashes during the startup

http://bugs.winehq.org/show_bug.cgi?id=10040

Summary: Steam crashes during the startup
           Product: Wine
           Version: 0.9.47.
          Platform: PC
               URL: http://steampowered.com/
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: minor
          Priority: P2
         Component: wine-crypt32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

While starting steam crashes and writes the crash log. However it continues on
and starts. It seems it allows some parts to fail start up but still be usable
to say play games.

Here is a snipped from the +relay:
-----
0017:Call advapi32.RegOpenKeyExA(80000002,0e76a2a8
"SOFTWARE\Microsoft\Cryptography",00000000,00020019,7b6428c4) ret=0e702b59
0017:Ret  advapi32.RegOpenKeyExA() retval=00000000 ret=0e702b59
0017:Call advapi32.RegQueryValueExA(00001910,0e76a2c8
"machineguid",00000000,7b6428cc,7b642ae0,7b6428c8) ret=0e702b87
0017:Ret  advapi32.RegQueryValueExA() retval=00000002 ret=0e702b87
......
0017:Call KERNEL32.OutputDebugStringA(7b6414c0 "hardware.cpp (590) : Assertion
Failed: bRet\n") ret=1002129f

So it's looking for 
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography]
machineguid

Which Wine does not have. Creating this value fixes the crash.
