[1803] almost unuseable with one core processors

At least my customer was quite satisfied.

That is the most important thing, after all.

If they ever get frustrated by the speed you could upgrade them to an SSD. A 32-bit system would only be able to see about 2.9GB of useable RAM even if you upgraded them to 4GB, so I'd suggest an HDD to SSD upgrade would be more effective.

As a postscript, I've just dropped the HDD I originally used to test a clean install of 32-bit 1709 Home back into the AMD V120 PC. But I'd forgotten that I'd subsequently used it to test a clean install of 64-bit 1803 Pro on another machine.

Surprisingly it worked quite well, despite only having 2GB to play with. The biggest surprise of all was that my V120 supports virtualisation, so I got it to successfully run a Hyper-V virtual machine (albeit a little on the slow side) before I swapped the drive out again.

All of this hearkens me back to MS-DOS 5 OS running the Win3.1 GUI on an AMD 80386SX/40MHz computer. A noticeable improvement for the GUI was the addition of an optional math coprocessor chip. More money could have gotten the 80386DX chip which included the math coprocessor. That was a pretty common understanding with the difference between Celeron and Pentium chips and AMD Athlon vs. Sempron whether factually completely accurate or not.
