So that the path returned by SHELL_FindExecutable would be fully qualified, otherwise CreateProcess will do its own path resolution which is not what we want. --- dlls/shell32/shlexec.c | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-)

For ShellExecute, if the specified file is found, we will try running it anyway, even if it doesn't have a "program" extension.
Windows associations will take precedence over this. --- dlls/shell32/shlexec.c | 23 ++++++++++++++++++++--- 1 file changed, 20 insertions(+), 3 deletions(-)
