Long time ago I tried to boot Win3.11 on 4Mb on a PC XT that I had built (including soldering components). It booted but was horribly slow, so I doubt Win95 was usable on 4Mb.
Was that 4Mb or 4MB. We had Win 3.11 on 386 with 1MB RAM, which was running but slow. My father paid a large(3rd-world) sum to get it upgraded to 4MB after which it was fast enough for another 6 years including Office, Wordperfect, Visual Basic, Pagemaker etc.
With 8Mb the speed was OK for me and most PC XT at the time were not perceived as slow for office or industrial usage.
People used office software like Multiplan or Wordstar without complaining about speed even on Z80 machines. They complained much more about capabilities to connect their brand new printer, or the slowness and limitations of their floppy disks, etc.
