Windows 7: BCDEDIT settings

If one has activated the /3G switch at a command prompt using the command: BCDEDIT.EXE /SET INCREASEUSERVA 3072, how would I go about returning this setting to original settings?

Thanks PolishPaul. I also read on another forum that one can enter "bcdedit.exe /delete increaseuserva" at the command prompt. This supposedly removes the line entirely, back to system default which is I guess 2048 anyway.

I typed this in and got the message that the instruction was completed succesfully, guessing it also works.
