Hi Arden,

Thank you for your note. If you would like to disable this shortcut, you
can do so by editing the Windows system registry.

Please note that editing the Windows registry is an advanced process. You
may prefer to contact your system administrator.

That said, you should be able to solve the problem by editing the
following registry keys:

In "HKEY_CURRENT_USER\Software\Google\Google Desktop\Preferences" create a
DWORD value named "hot_key_flags".

Setting this value to:

 - "0" disables both Ctrl-Alt-G and Windows-G

 - "1" disables Windows-G, but leaves Ctrl-Alt-G enabled

 - "2" disables Ctrl-Alt-G, but leaves Windows-G enabled

 - Removing the key or setting the value to "3" or higher will enable
both keys.

Once disabled, please restart your computer for the changes to take
effect.

Regards,
The Google Team
