Randomly can't run commands in PowerShell

i'm trying run ssh powershell , says ssh isn't recognized cmdlet, function, script file etc.

i knwo fact path ssh.exe in path can normal cmd prompt. can use other non powershell commands in powershell such, there other random commands don't work also.

ssh.exe in c:\program files (x86)\openssh\bin , 100% in path variable. can print out $env:path , see there. why be?

kyle

it might double quotes around

"c:\program files (x86)\openssh\bin"

that confusing powershell.

 

i don't see double quote wrappers in $env:path value:

 

c:> $env:path
