Win10 How to disable screen autorotation (programmaticaly or in a batch command)

Question

I´m writing a Windows 10 application using C++/CLI. The application is going to run on a portable computer (that runs standard Win10 SO, not the tablet version).

This portable computer has autorotation, but I need to keep my application only in Portrait configuration.

I want to disable screen autorotation when the application comes up. Is there a C++/CLI command, a C# command or a batch command that I can do it programatically (the batch would be called from my app) ?

Answer 1

Use regini.exe, with a parameter file specifying the key to set:

AutorotateOff.reg:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation Enable = REG_DWORD 0DWORD

Command to issue on command line with elevated right: c:\>regini AutorotateOff.reg

Been a while, but this should do the job:

RegistryKey regKey = Registry.LocalMachine.OpenSubKey("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AutoRotation", true);

if(regKey != null)
{
   regKey.SetValue("Enable", "0", RegistryValueKind.DWord);
   regKey.Close();
}
