The start menu features a Developer PowerShell for VS 2022 which defaults to x86:
PS C:\> (Get-Command link.exe).Source
C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.44.35207\bin\HostX86\x86\link.exe
How can I change it to x64/amd64?
Create a start menu entry by copying the original and adding -Arch amd64
cp "$env:ProgramData\Microsoft\Windows\Start Menu\Programs\Visual Studio 2022\Visual Studio Tools\Developer PowerShell for VS 2022.lnk" "$env:APPDATA\Microsoft\Windows\Start Menu\Programs\x64 PowerShell.lnk"
$wsshell = New-Object -ComObject WScript.Shell
$shortcut = $wsshell.CreateShortcut("$env:APPDATA\Microsoft\Windows\Start Menu\Programs\x64 PowerShell.lnk")
$shortcut.Arguments = $shortcut.Arguments -replace '(Enter-VsDevShell)', '$1 -Arch amd64'
$shortcut.Save()
Which will give you x64/amd64:
PS C:\> (Get-Command link.exe).Source
C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.44.35207\bin\HostX64\x64\link.exe
