Well, for an installation that old it would probably be quite helpful if you did a clean fresh install. A 32bit Windows can deal just fine with 4GB of memory (not so much with larger memory), you can make about 3GB of that available to user processes with a boot option (at the expense of memory reserved for the kernel space). > I'll be following the steps outlined in this post or a similar one: > > https://www.howtogeek.com/228042/how-to-switch-from-32-bit-windows-10-to-64-bit-windows-10/ > > It's somehow clear I thankfully won't need to upgrade to cygwin64 > until later, I mean it seems I'll be able to still use my 32 bit > cygwin after I upgrade to 64 bit Windows 10, I just don't know what > I'll need to tweak / migrate so that the new Windows installation > installed on top of the same drive that currently holds the 32 bit > cygwin knows it's there.

You can keep using a 32bit Cygwin on any Windows 64bit desktop version in existence so far, they all come with the WoW64 subsystem that is necessary to run 32bit Windows applications. > I might also be wrong and need to install cygwin64 as I upgrade > Windows. Fingers are crossed. However, I'd still recommend you make the switch to a 64bit Cygwin if you have the option.
