Steps to repeat:
  - Press F2

Behaviour:
  - The explorer opens and an error message pops up

Expected behaviour:
  - The explorer opens without any error message

The behaviour is the same in both 0.9.8 and 0.9.9-7930.

Extract from error log:
  16:07:49: Can't read value of 'HKCR\Folder\shell\explore\command' (error 2:
the system cannot find the file specified.)
  16:07:49: Can't read value of 'HKCR\Folder\shell\opennewprocess\command'
(error 2: the system cannot find the file specified.)
  16:07:49: Can't read value of 'HKCR\Folder\shell\opennewwindow\command' (error
2: the system cannot find the file specified.)

The cause seems to be that the registry structure for the default explorer has
been changed in Windows 7.

The 'HKCR\Folder\shell\explore\command' does not have a value. Instead there is
a string, 'HKCR\Folder\shell\explore\command\DelegateExecute' containing a GUID
which resides in 'HKCT\CLSID\{GUID}' and contains:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\CLSID\{11dbb47c-a525-400b-9e80-a54615a090c0}]

------------

I cannot see any useful information that can be extracted here, so my suggestion
is to use the command

  "%SystemRoot%\explorer.exe" "%1"

if the 'HKCR\Folder\shell\explore\command' key has an unset value.

Used software:
  Windows 7 RC 64-bit version
