vim, g++ logs and stuff

So I got vim for on a school computer (running windows of course), works fine and everything, except for any commands requiring an exclamation mark in front of it (like :!q or :!sav). Whenever I try to do :!q, I get the following message in a new command prompt:

C:\WINDOWS\system32\cmd.exe /c q
'q' was not recognized as an internal or external command, an application or a batch-file.
shell returned 1
Hit any key to close this window...

Any idea as to how to solve this?

And to finish off, I want to know if there's any way of telling g++ to print it's errors to a log file?
