#Enable Game Mode In Windows 10 Creators Edition Using PowerShell Commands
#Enable Game Mode in Windows 10 Creators Edition only. This does not work in previous or the latest version of Windows 10. Windows Key + G will toggle Game Mode once the changes have been made. This command appears to have no effect in 1909.
#Just the command
If (Test-Path HKCU:\Software\Microsoft\GameBar) {Get-Item HKCU:\Software\Microsoft\GameBar|Set-ItemProperty -Name AllowAutoGameMode -Value 1 -Verbose -Force}
#The Longer Story…
#The above command enables Game Mode. The command below disables Game Mode. Again this feature is only available in Windows 10 Creators Edition. These commands work in both PowerShell and PowerShell Direct.
If (Test-Path HKCU:\Software\Microsoft\GameBar) {Get-Item HKCU:\Software\Microsoft\GameBar|Set-ItemProperty -Name AllowAutoGameMode -Value 0 -Verbose -Force}
#Check Game Bar Registry Key And Existing Configuration (1=Enabled, 0=Disabled)
#If the GameBar registry key has no properties then Game Mode is disabled. If allow AllowAutoGameMode is set to 1 then Game Mode is enabled. If it is set to 0 then AllowAutoGameMode is disabled.
Get-Item -Path HKCU:\Software\Microsoft\GameBar -Verbose|ft -a
#▲Game Mode Disabled (Installation Default)
#▲Game Mode Enabled
#Enable Game Mode In Windows 10 For The First Time
#The -Force switch is used to a skip using New-Item or New-ItemProperty commands but specifying -Force will delete the key and recreate the key and you will lose all sub-keys.
If (Test-Path HKCU:\Software\Microsoft\GameBar) {Get-Item HKCU:\Software\Microsoft\GameBar|Set-ItemProperty -Name AllowAutoGameMode -Value 1 -Verbose -Force} #Enable Game Mode
#Disable Game Mode In Windows 10 Once Enabled Or To Manually Set Game Mode To Disabled
#If you just remove the registry key then Game Mode will stay enabled. Changing AllowAutoGameMode to 0 will disable Game Mode once it has been enabled.
If (Test-Path HKCU:\Software\Microsoft\GameBar) {Get-Item -Path HKCU:\Software\Microsoft\GameBar|Set-ItemProperty -Name AllowAutoGameMode -Value 0 -Verbose -Force}
#Check If AllowAutoGameMode Registry Property Is Enabled (1=Enabled, 0=Disabled)
#Is similar to the other command to check Game Mode status with more information about the registry key. This command will error if AllowAutoGameMode is not there but just means that Game Mode is disabled by default.
Get-ItemProperty -Path HKCU:\Software\Microsoft\GameBar\ -Name AllowAutoGameMode -Verbose|fl
