Hi all, just wanted to share a small discovery I have made in the hope that it will helpful.
Windows 7 Build 6801 seems to to use the least RAM of any "standard" (Unedited, official release) Windows 7 version there is. Disabling the Windows Update and Defender services brings RAM usage down to <330mb average. For comparison, 7 Starter with the same two services disabled is somewhere above 400mbs usage consistently.
