You could run a batch file with a setlocal

or on cmd line start another cmd.exe which inherits the current environment but changes are volatile.

cmd /c "SET MYVAR=1&myprogram.exe"

Try this command:

set Foo=bar & abc.exe & set Foo=

This command does:

Set Foo variable with bar value.
Run abc.execommand.
Unset Foo variable by adding blank value.
