FOR /F loop runs within a temporary instance of cmd.exe

This is probably well-known to batch gurus

C:\Users\Andrew>tasklist /FI "username eq %username%" | findstr /I cmd.exe
cmd.exe                      14836 Console                    1      3,020 K

C:\Users\Andrew>for /F "delims=" %A in ('tasklist /FI "username eq %username%" ^| findstr /I cmd.exe') do @echo %A
cmd.exe                      14836 Console                    1      3,068 K
cmd.exe                       8084 Console                    1      2,660 K

Re: FOR /F loop runs within a temporary instance of cmd.exe

Also that second copy of CMD will inherit any variables you have set, so I think it is a COPY of the current CMD instance rather than a completely fresh instantiation.
