[USERINIT]
- Use explicit unicode functions where possible.
- Use ARRAYSIZE(foo) instead of sizeof(foo)/sizeof(foo[0]).
- Don't hardcode some buffer sizes.
- Try reducing level of code indentation in some functions.
- Make StartShell and StartInstaller return a boolean (TRUE: success; FALSE: failure). Will be needed in the next commit.
- Remove a useless "#pragma warning".
