Arctic Machine Help

I need help with ARctic machine …
I used the metasploit exploit

Is something has changed in metasploit? …by setting 100 to httpclienttimeout i am getting a windows shell …
when i background the sesion is its showing as linux shell instead of a windows
Local exploit suggester is also considering it as linux shelll and MS10-092 also considers as linux shell … not able to privesc

I am not able to open powershell from the low privileged windows shell

Is there any issue with this machine ?
