Im wondering how i send powershell the variable 'asset' from my batch file.

Here is my .bat file content

@Echo off  
cls
Color E
cls

@echo Enter asset below
set /p asset=

@echo.
@echo your asset is %asset%
@echo.
goto startusmt

:startusmt
@echo.
@echo executing psexec ...
@echo.

SET ThisScriptsDirectory=%~dp0
SET PowerShellScriptPath=%ThisScriptsDirectory%RemoteUSMT.ps1
PowerShell -NoProfile -ExecutionPolicy Bypass -file %PowerShellScriptPath% %asset%
psexec \\%asset% -u domain\username -p password cmd 

goto EOF

:EOF 
PAUSE

You can use $env:variable_name syntax to access curent cmd environment variables from powershell. To get hold of your variable you'd use $env:asset
To try, open cmd, do set "myvar=my value", start powershell, do $env:myvar (this will simply print it, but of course you can use it as any other ps variable)

Just as a sidenote, ps has good help system. If you do help env it will list two relevant topics which you can examine in turn to get detailed information.

Hope this helps
