TIA.

I personally prefer gflags.exe and use regedit to double check :-) Agree. I personally prefer gflags.exe and use regedit to double check :-)

This is actually a wrong way of doing that. You need to use either 32bit version of gflags.exe just like you have mentioned or 32bit version of regedit/reg without Wow6432Node in the path. Try it in Windows 7 x64 and you will see the difference. :-) > HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\…
