Hi, I wrote the integrated terminal. The advice mentioned will open 32-bit version of Powershell, for 64-bit you need to use a different path:

"terminal.integrated.shell.windows": "C:\\WINDOWS\\sysnative\\WindowsPowerShell\\v1.0\\powershell.exe"

C:\WINDOWS\sysnative should be a symlink to C:\Windows\SysWOW64, see https://github.com/Microsoft/vscode/issues/7095#issue-157913... for more info
