I modified the PATH system variable, PATH variable can be displayed correctly in cmd, but the cmder doesn't work
How to reload the system variable in cmder, I restart cmder, it still doesn't work
Restarting computer can work, is there a better way of doing it? Please help me, thank you

I've tried messing with user and system env properties for HTTP_PROXY and to be honest I've never found a good way to do it and guarantee they change.

I tried a powershell function with these [environment]::SetEnvironmentVariable("http_proxy", $proxy, "User") and to unset "http_proxy", $null, "User"

but like I say, seemed unreliable to take effect.

I found cmder can reload system variables when it launched
