Sets the registry view used by RegRead, RegWrite, RegDelete and registry loops.
Specify 32 to view the registry as a 32-bit application would, or 64 to view the registry as a 64-bit application would.
Specify the word Default to restore normal behaviour.
This command is only useful on Windows 64-bit. It has no effect on Windows 32-bit.
On 64-bit systems, 32-bit applications run on a subsystem of Windows called WOW64. By default, the system redirects certain registry keys to prevent conflicts. For example, in a 32-bit script,
HKLM\SOFTWARE\AutoHotkey is redirected to
HKLM\SOFTWARE\Wow6432Node\AutoHotkey. SetRegView allows the registry commands in a 32-bit script to access redirected keys in the 64-bit registry view and vice versa.
The built-in variable A_RegView contains the current setting. Every newly launched thread (such as a hotkey, custom menu item, or timed subroutine) starts off fresh with the default setting for this command. That default may be changed by using this command in the auto-execute section (top part of the script).
